This purchase comes with 2 different (editable in Microsoft Word) sets of flow charts for your elementary/intermediate classroom. These flow charts are visual references for your students when solving word problems involving addition or subtraction. They help guide students towards choosing the correct operation when solving word problems. Each set of flow charts come in color and black/white. One set includes a CUBES reference (CUBES is a problem solving strategy which includes the following steps: Circle the numbers, Underline the question, Box the key words, Evaluate and Solve) with addition and subtraction key words listed on the flow chart for quick reference. These would be great in an interactive notebook or blown up as a poster. My students use these all of the time and find them very useful! I also have 4 operation and multiplication/division flow charts for purchase and a bundle which includes all of my flow charts with my key word reference. Thank you for your purchase!
