President's Message
by Bonnie Angel, GCTM President

As I begin preparations for the next school year, I am reflecting on the changes that have taken place in mathematics classrooms in the seven years that I have been working with districts in the North Georgia RESA area and with educators across the State. During this time we have transitioned from the Georgia Performance Standards (GPS) to Common Core Georgia Performance Standards (CCGPS) and now to the Georgia Standards of Excellence (GSE). This has brought about changes to students' behavior in the classroom, teachers' instructional methods, and my own mathematical thinking. I often think about my middle school students and hope that I did not damage them or cause unnecessary anxiety for them. I know I am a much better teacher today because of my personal growth and many conversations with colleagues.

I now realize that I am not required to know all the answers. I blame this expectation on my nephew, Hunter. When he was in elementary and middle school, he would say, "My Aunt Bonnie is a teacher and she knows everything!" Talk about pressure! I understand that it is okay for teachers to say, "I don't know", "I am not sure", and "Let me think about this more."

Teachers' mindsets are moving from the idea that we must give students all the information they need up front and have them work independently. Students are now given problems to solve, expected to ask for the information they need, and allowed to work with other students to develop a solution instead of depending on the teacher for the one correct answer and strategy. We understand that constant assessment of students to adjust instruction is more efficient than waiting for the "end-of- unit" test to uncover what needs to be retaught.

Students are more engaged in the mathematics because problem solving is active, not passive. Allowing students to work together appeals to the social nature in all of us. Having students explain their thinking and justify their answers and strategies gives ownership of the learning back to the students. I would have been a much better math student and problem solver if I had been taught this way.

Teacher collaboration certainly contributes to this professional growth. I have learned how to help students make connections between mathematical ideas through rich mathematical discourse. For example, one teachers may create open tasks that require students to find patterns and describe how they see these patterns (using dot cards during Number Talks, for example) instead of simply determining the 100 th pattern or finding the equation. This type of task allows for differentiation that provides access to all students--"low floor and high ceiling". As adults, we get excited when we make these connections. How may we create atmospheres for learning that allow students to experience this excitement for themselves? For more ideas, professional connections, and mathematical discourse of how to engage your students in mathematics, consider attending the Summer Academies offered by GCTM. Information about the Summer Academies is provided below.

Synergy: A Combined Effect Greater than the Sum of their Separate Effects
Kristi Caissie

All over the state of Georgia this summer, teachers will be gathering together to improve their mathematical pedagogy! Once again GCTM will be hosting the Summer Mathematics Academies in three different locations. You have the opportunity to join a professional learning session for two days with peers that teach in the same grade-band as you. Along with a focus on creating quality mathematical discourse in your classroom, you will have the opportunity to collaborate with others. Teachers helping teachers! As one participant from last summer said that the best thing about the Summer Academies was "getting to talk to other teachers who face the same struggles that I do in the classroom."

Facilitators working in the area of mathematics every day will host the following sessions:

K-1st Grade
2nd-3rd Grade
4th-5th Grade
6th-8th Grade
Algebra I
STEM using Texas Instruments

These sessions will focus on quality tasks that model effective math teaching practices. The facilitator will demonstrate and teach the participants how to set clear goals, anticipate how the students will solve a problem and how to use this anticipation to deliberately create mathematical discourse in the classroom. Nothing screams high-quality math lesson better than when the students have the opportunity to share and discuss their learning by explaining how they solved the problem. During the sessions this summer, teachers will also learn how to sequence when students share to get the most learning and growth from the class of students. At times, students will better understand the lesson if a misconception is shared first. However, other lessons will benefit the most from students sharing less sophisticated strategies first. During the 2018 Summer Mathematics Academies, participants will learn the importance of sequencing the share time portion of the lesson. Using the strategies learned from the sessions this summer, teachers will learn to have more control over the learning of their students while developing quality discussions between and amongst students.

A new introduction to last year's Academy was the Lunch-N-Learn! Summer Academy participants had the chance to sign up for an extra class taught during lunch. Each participant was given a free lunch while they learned about 3 Act Tasks. This activity was so successful that we are working to increase the opportunity for both days of the Academies! Participants will have the opportunity to gain extra knowledge during lunch both days!

Free, free, free is every teacher's favorite word, especially if it pertains to classroom materials! Many participants were lucky enough to win FREE classroom materials. Everything from teacher books to free manipulatives were given away at each Academy! The winners were so excited to have something extra to take back with them to the classroom.

If you are still uncertain about spending two days this summer increasing your mathematical pedagogy, then see what others had to say about the 2017 Summer Mathematics Academies!


Join us for the 2018 Summer Mathematics Academies where we will become greater than the sum of our separate effects!

GCTM at the Capitol
T.J. Kaplan, Advocacy

GCTM Hosts Math Day at the State Capitol

On February 13th, 2018 a group from the Georgia Council of Teachers of Mathematics travelled from across the state to Atlanta for Math Day at the Capitol. The day began in the Senate Chamber where Senate Finance Committee Chairman Chuck Hufstetler (R-Rome) recognized GCTM with a resolution and invited Bonnie Angel to address the members of the Senate. This provided an opportunity for Bonnie to thank the members of the Senate for their support of mathematics teachers across the state and remind them of the critical work that GCTM does to support quality mathematics instruction in Georgia.

The group then hosted a lunch in the capitol where numerous key influencers (listed below) came by to learn more about GCTM's role in Georgia and discuss key education issues that are facing the state. This provided a critical opportunity to update these influential leaders on the work of GCTM's members, thank them for their leadership, and discuss relevant legislation that is pending in the House/Senate.

The Georgia Council of Teachers of Mathematics would like to extend its sincere thanks to the following leaders who came out for the math day lunch and took time out of their day to speak to our group. We are grateful for your partnership and look forward to continuing to work with you to promote high quality mathematics education in Georgia!

Senator Brian Strickland (R-McDonough)
Senator Josh McKoon (R-Columbus)
Senate Higher Education Chairman Fran Millar (R-Atlanta)
Senator Larry Walker III (R-Perry)
Senator Ed Harbison (D-Columbus)
Senator Kay Kirkpatrick (R-Marietta)
Senate Minority Leader Steve Henson (D-Tucker)
Senator Blake Tillery (R-Vidailia)
Senator Horecena Tate (D-Atlanta)
Senator Matt Brass (R-Newnan)
Senator John Albers (R-Alpharetta)
Senator Chuck Payne (R-Dalton)

Legislators Attend GCTM Events Throughout Georgia

Representative Wes Cantrell (R-Woodstock) visited Clark Creek Elementary School on October 26th during which time school administrators and GCTM leadership spent the morning briefing him on the work that goes into preparing teachers for the classroom, supporting their ever-changing needs, and ensuring all students are given the tools they need to be successful. Rep. Cantrell is a Subcommittee Chairman on the House Education Committee and plays a key role in shaping education policy in Georgia. The classroom visit provided him with an opportunity to spend quality time with mathematics teachers learning about the challenges they face and engaging in meaningful discussions about how local and state policies affect their work. GCTM is grateful to Representative Cantrell for the time that he spent with the group and for his willingness to learn about what our members do each and every day.

Below are some pictures from the visit to Clark Creek Elementary School:

GCTM also had the pleasure of hosting Senator Matt Brass (R-Newnan) and Senator Tonya Anderson (D-Lithonia) at the 2017 Georgia Math Conference at Rock Eagle. This visit was a critical opportunity to further demonstrate to key legislators the role that GCTM plays in providing mathematics teachers with the resources they need to prepare students for success. Senator Brass and Senator Anderson both spent substantial time at the event and were able to visit a number of breakout sessions to see first hand the value of the conference. GCTM is extremely grateful to both legislators for making the trip out to Rock Eagle!

The WHOLE Truth About Fractions
by Ha Nguyen & Joy Darley

Proficiency with fractions is an important component for building the groundwork for learning more advanced mathematics (Wu, 2002; Fennell, 2007; NMAP, 2008; Wu, 2014). Yet, historically students of all ages seem to have difficulty with fractions (Hecht, Vagi, & Torgeson, 2007; Mazzocco & Devlin, 2008; NMAP, 2008). In 2010, the Common Core State Standards for Mathematics (CCSSM) (CCSSI 2010) were released to address the skills and knowledge all students need to know to be College and Career ready. Among these standards, some are designed specifically for developing an understanding of fractions as numbers. In order to reach this understanding, many mathematicians and mathematics educators agree that all fractions should be understood in reference to a unique whole (Wu, 2002; NMAP, 2008; Beckmann, 2014). In addition to unpacking CCSSM on "developing understanding of fractions as numbers," the purpose of this paper is to share fraction tasks implemented in a class of K-8 preservice teachers (PSTs) with the intention of helping third-grade students to focus on the whole when learning fractions.

Unpacking CCSSM: Developing understanding of fractions as numbers

Figure 1. "Does the shaded region represent 5/6 or 5/3? We cannot say unless the whole is specified." (Beckmann, 2014)

Consider the visual in figure 1: Does the shaded region represent 5/6 or 5/3? In fact, the answer could be both of these fractions. The answer to this question depends on the individual student's choice of the whole.


Understand a fraction 1/b as the quantity formed by 1 part when a whole is partitioned into b equal parts; understand a fraction a/b as the quantity formed by a parts of size 1/b

Figure 2. CCSSM: Developing understanding of fractions as numbers. 

CCSSM expects mathematically fluent third-grade students to develop an understanding of fractions in terms of unit fractions (fig. 2) and to begin to see fractions as numbers (CCSSI 2010). When given a fraction, third-grade students should be able to use CCSS.MATH.CONTENT.3.NF.A.1 to represent the fraction with a picture or scenario. When given a picture or scenario, does this mean that students can use this standard to arrive at a unique fraction? The answer to this question is yes, but with one important condition. The student must first choose the whole. To address this, let's revisit the shaded region shown in figure 1. Based on the student's interpretation of the whole, CCSS.MATH.CONTENT.3.NF.A.1 (see fig. 2) can be correctly applied to obtain two different fractions.

As table 1 reveals, the student first interprets the whole as the area of either one large rectangle or the area of both large rectangles and then uses the standard to interpret the unit fraction 1/b as the area of one part (shaded in green) when the area of the whole is divided into b parts of equal area (Step 1). Notice that both 1/6 and 1/3 could be considered correct fractions according to the student's interpretation of the whole. After the unit fraction is determined, the student then uses this to either get 5/6 or 5/3 for the fraction a/b represented by the area of five of the equal parts shaded in green (Step 2). 

Table 1

Same Visual, Two Different Interpretations of the Whole Resulting in Two Different Fractions. Are both fractions correct?

As shown above, unless the whole is made explicit, the fractions matching the figures can be interpreted in different ways. Therefore, we suggest that students should intentionally state the whole as the first step prior to naming a fraction corresponding to a given figure. Once the whole is specified, students can confidently follow the standard (see fig. 2) in order to arrive at a unique fraction. 

Fraction Tasks with Purposeful Ambiguity

Seemingly counterintuitive, in order to help our PSTs arrive at an understanding of the importance of the whole, we decided to introduce the ambiguity found in step 1 in Table 1. Not only does "ambiguity allow students to discuss deep, rich mathematical ideas" (Danielson, 2016), but it also promotes meaningful mathematical discourse (NCTM, 2014). Thus, we created Task 1 (see fig. 3). 

Task 1.                                                                                                                                           Name_____________________________

Jack has a package of 2 candy bars. He opens the package and divides each candy bar into 3 equal portions. Jack eats 1 portion (shown in green). How much does Jack eat? Explain your answer.

Figure 3. Task 1 

After a few minutes attempting Task 1 individually, students put 1/6 or 1/3 as their answers, and many did not include units in their responses. Some student work was selected and displayed in Figure 4

Figure 4. Student Work on Task 1. 

Once the PSTs completed the task, they were encouraged to share their answers with the whole class. The conversation went as follows.

Teacher: What is your answer and why?

Hudson: I put 1/6, because Jack ate one portion out of 6 portions total. So 1/6 of 2 candy bars.

Teacher: Did anyone give a different answer on your paper?

Javier: I put 1/3, because Jack ate one piece out of 3 pieces in 1 candy bar. So he ate 1/3 of a candy bar.

Teacher: 1/6 and 1/3 are two different fractions. Can both answers be correct?

Tracy: It depends on your whole, whether you see the whole as 2 candy bars or just 1.

Lucy: Now that you said that, I can see that the answer could be 1 portion, too, because the whole can be 1 portion, and Jack ate one.

Teacher: Great! I also noticed that when each of you explained your answer, you didn't just say 1/6, 1/3, or 1 but you said 1/6 of 2 candy bars, 1/3 of 1 candy bar, or 1 portion. How does doing that help with your explanation?

Hudson: It made my answer clearer.

Kim: 1/6 is not the same as 1/3, but 1/6 of 2 candy bars is the same amount as 1/3 of 1 candy bar. Same as 1 portion.

Teacher: That is really great! So what did all of you learn from this?

Whole Class: The whole maters and units are important.

An "aha moment" occurs when the students realize that once the whole has been defined, the ambiguity disappears. The question ("How much does Jack eat") in Task 1 is purposely vague and consequently elicits ambiguous answers. After all, what exactly does "how much" mean? What if the question in Task 1 is asked more explicitly? Would this be less confusing for students? In order to address this, students were put in groups to work on Task 2 (see Fig. 5).  

Figure 5. Task 2.

The purpose of Task 2 is for students to recognize the importance of the whole when working with fractions. In this task, students in each group were asked to write a question to match each of the intended answers they proposed for Task 1 and to identify the implied whole in each case. Student responses on Task 3 were shared with the class, and a student's work was selected to display in Figure 6. After working in groups and generating these suggested questions, students gained a clearer interpretation of the whole so that they will be more apt to first determine whether the whole in reference to the question is one object (a candy bar) or a collection of objects (two candy bars) prior to naming a fraction in response to a given problem. 

Figure 6. Student Response on Task 2.

Student Reflections on Tasks 1 and 2

After completing Tasks 1 and 2 in class, the PSTs reflected on what they learned from working on the tasks by filling out a Google Form on their own electronic devices. Overall, students expressed that they learned the importance of identifying the whole before naming a fraction as well as why they should include both numbers and units in their answers. Some said that at first they assumed either 1/3 or 1/6 to be the answer to Task 1 (Fig. 3), but then they realized that the answer could be different, depending on the chosen whole. Many students stated that the tasks helped them foresee issues that may arise in their future classroom when they become teachers. Several students mentioned how helpful it was to work in groups and how much they learned from other students. A sample of student reflections on two tasks is shown in Figure 7

Question 1:  Did you have any misconceptions before doing this Candy Bar Task (Task 1)? If so, what were they, and how did this activity help you address them?

Yes. At first I could not figure out how to answer the question. After completing the task, I found that I have to find the whole and find the fraction of the whole to answer the question.

Question 2: Did you have any misconceptions before doing this Candy Bar Task (Task 2)? If so, what were they, and how did this activity help you address them?

How to word the suggested questions confused me in the beginning. After the task, I found that specific words need to be used to eliminate ambiguity.  

Figure 7. Student Reflections on Learning from Tasks 1 and 2 

Closing Thoughts

Reflections from students showed that the Tasks 1 and 2 (Figures 3 & 4) not only helped them see the importance of identifying a whole when learning fractions and why they should include units in their answers but also allowed them to work backwards to design questions to match their "intended answer with no ambiguity." Moreover, they indicated that they learned from others through group discussion. In conclusion, we would like to make the following suggestions to teachers. First, have students identify the whole prior to determining a fraction from a picture or word problem (see CCSS.MATH.CONTENT.3.NF.A.1 in fig. 2). In addition, students should include units with their answers. Finally, when working with fractions, pose problems that introduce ambiguity so that students will have conversations concerning the importance of the whole. Otherwise, make the whole in reference to the question explicit. For instance, ask "What part of a candy bar did Jack eat?" or "What fraction of the package of candy bars did Jack eat?" We encourage mathematics educators to try these tasks or create their own so that students will recognize the important role that the whole plays in understanding fractions.
