After exploring and understanding various strategies for solving addition and subtraction problems, our next unit in Math is all about putting those skills to the test with some problem solving! As we tackle word problems, we are going to put on our critical thinking hats and become detectives, identifying key words that signal which operation to use along with creating bar models to visually show (and check!) our understanding of the question. Here are a few videos that we watched that do a good job introducing bar models or the part part whole method. First one is a video from learnzillion.com which is a great resource for video mini lessons on a variety of topics. HERE It requires you to sign up but as a teacher I feel that it is a great resource. Another video demonstration of how to use bar models for solving word problems: |
Bar models also lead into algebra and understanding the relationship between addition and subtraction! I am excited at making what seems like a complicated subject (algebra) and presenting it in a way they can understand and see!
