Model with mathematics. Identify the mathematical elements of a situation and create a mathematical model that shows the relationships among them. Identify important quantities in a contextual situation, use mathematical models to show the relationships of those quantities, analyze the relationships, and draw conclusions. Models may be verbal, contextual, visual, symbolic, or physical. Third grade students apply addition and subtraction strategies to solve word problems. Listen and look for students that exhibit the following behaviors: • identify the correct prior knowledge that needs to be applied to solve a problem • identify the hidden question(s) in multiple-step problems • use numbers, symbols, and words to solve problems • identify the operation(s) needed to solve a problem • use estimation as appropriate.

Sentence Frames: •

I used ________ to show how I solved the problem. • My ___(picture, equation, model) ___ represents the problem because _________.
