1.MP.4 Model with mathematics. Identify themathematical 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. First grade students use strategies they know, such as working on an open number line, to model subtracting tens. Listen and look for students that exhibit the following behaviors: • identify the correct prior knowledge that needs to be applied to solve a problem • use numbers, symbols, and words to solve problems • identify the operation(s) needed to solve a problem. Sentence Frames: • I already know __________ about this problem • The number sentence I can use to describe this situation is _______________ Focus Standards Curriculum Supports – enVision 2020 Vocabulary
