Solve word problems, requiring more than 1 calculation, by drawing models to identify the operation needed at each step. Label information to understand what the numbers mean, and to accurately decide what to do next.
Given the starting amount (total) and how much is taken away (change), find the ending amount (result). Use a visual model to show the relationship between the parts and total. Calculate the unknown part using a Make 10 or Missing Part strategy, and ten frames, number bonds, or mental math. Prerequisites: 1-14 ○ 1-60
Compare 2 numbers using the word "more" in an intuitive way. Given the smaller number and how many more is the larger number, find the larger number. Add the difference to the smaller number using a Make 10 addition strategy and ten frames, number bonds, or mental math. Prerequisites: 1-73 ○ 1-45
Model 2-step word problems that require part-whole thinking in both steps. Scaffold the problem by asking explicitly what needs to be solved in each step. In the first step, join 2 parts together. In the second step, join or remove another part. For clarity and practice, draw 2 bar models, 1 model for each step. Prerequisites: 2-36
