## The Math Forum's Elementary Mathematics Practices Blog

With an Internet history dating back to 1992, the Math Forum @ Drexel brings to Mathlanding a community discussion area focused on the Mathematical Practices in Kindergarten through Grade 5 classrooms. What are teachers doing to encourage their students to develop these practices? What challenges are they encountering? What successes are they experiencing? What ideas are they willing to try?

### Collections on Mathlanding

All of the “Collections” on Mathlanding are of value but, in particular, check out these two new collections: Professional Development: CCSS Practice Standard 3 Classroom Collection: Fostering CCSS Practice Standard 3 Both collections point you to resources to help teachers integrate Mathematical Practice Standard 3 into their classroom routines. In addition to activities/resources to use, [...]

Welcome to our area focused on the Standards for Mathematical Practice of the Common Core State Standards. We invite you to participate in conversations targeted at practices to implement in Kindergarten through Grade 5 classrooms. Notice the top (tabbed) navigation allows you to view pages with conversation starters focused on: Grades K-1 Grades 2-3 Grades [...]

### 2-3: Mathematical Practice #1

1. Make sense of problems and persevere in solving them. How are second and third grade teachers helping their students make sense of problems? During a recent online course focused on problem solving in elementary classrooms, these thoughts were shared in our discussions. I’ve received permission to quote them and provide them here as starting [...]

### 2-3: Mathematical Practice #2

2. Reason abstractly and quantitatively. How are second and third grade teachers helping their students reason abstractly and quantitatively? How can students be helped to: make sense of quantities and their relationships in problem situations? decontextualize — to abstract a given situation? represent a problem symbolically? manipulate the representing symbols as if they have a [...]

### 4-5: Mathematical Practice #1

1. Make sense of problems and persevere in solving them. How are fourth and fifth grade teachers helping their students make sense of problems? During a recent online course focused on problem solving in elementary classrooms, these thoughts were shared in our discussions. I’ve received permission to quote them and provide them here as starting points we [...]

### 2-3: Mathematical Practice #3

3. Construct viable arguments and critique the reasoning of others. How are second and third grade teachers helping their students construct viable arguments and critique the reasoning of others? How can students be helped to: understand and use stated assumptions, definitions, and previously established results in constructing arguments make conjectures and build a logical progression [...]

### 2-3: Mathematical Practice #4

4. Model with mathematics. How are second and third grade teachers helping their students model with mathematics? How can students be helped to: apply the mathematics they know to solve problems arising in everyday life, society, and the workplace write an addition equation to describe a situation identify important quantities in a practical situation map [...]

### 2-3: Mathematical Practice #5

5. Use appropriate tools strategically. How are second and third grade teachers helping their students use appropriate tools strategically? How can students be helped to: consider the available tools when solving a mathematical problem use pencil and paper, concrete models, a ruler identify relevant external mathematical resources use technological tools to explore and deepen their [...]

### 2-3: Mathematical Practice #6

6. Attend to precision. How are second and third grade teachers helping their students attend to precision? How can students be helped to: communicate precisely to others use clear definitions in discussion with others and in their own reasoning state the meaning of the symbols they choose careful about specifying units of measure calculate accurately [...]

### 2-3: Mathematical Practice #7

7. Look for and make use of structure. How are second and third grade teachers helping their students look for and make use of structure? How can students be helped to: look closely to discern a pattern or structure. notice that three and seven more is the same amount as seven and three more sort [...]
