Free! Math Buddy Chat is a step-by-step method for students to solve word problems with a buddy. In this activity, students alternate between working independently and working together as they solve each problem. To make this activity really easy to implement, I created a PowerPoint that you can download and show to your students as you walk them through this 4-step problem-solving method.
This Addition and Subtraction Word Problems Grouped by Problem Type is a year-long resource for problem solving. Total of 156 problems. This packet makes a distinction between procedures (steps in solving a problem), models (which show the relationship between the numbers in the problem) and strategies for computation (such as count on, breaking part a number, etc.). Included are six different models to use with students (all based on inverted-v and bar models).
