Product Description
This product encourages students to think about which strategy they are using when solving mental addition and subtraction questions. Often when students provide an answer for a question, they find it challenging to articulate and communicate the strategies used and how they actually solved the problem mentally. By having students record their thought process and understand which strategies lend themselves to which types of questions, they are able to better communicate how to solve mathematical problems and become better equipped at answering problems more efficiently and accurately.
Begin by asking students addition questions. Ask them how they solved this problem. See if they can articulate their thought process. Go through each strategy with them, explaining what types of questions lend themselves to which strategies. Once they are confident, have them create their own questions for each type of strategy. My students loved this activity and was a great assessment tool!
