For the right side of the page, we used 4 magnifying glasses (for the CLUE words). We wrote the four operations on the outside and clue words for each operation under the flaps. Quick and easy.
For the left side of the page thinking, instead of the traditional left side of the page we do, we did another word problem to practice using the strategy (just like we did when we first did the CUBES entry). We are just finishing up our patterning unit, so I chose a problem we could use patterning strategies (like a T-table) to answer. We went through the problem as a whole group with students leading the conversation as to how to analyze the problem with the steps from CUBES (and color code the steps) and how to solve the problem.
Edit: I've had many requests to turn this into a resource, so I've made one which you can see here. Click HERE or on the picture to the right to preview it on TpT.
