The CUBES strategy is well known for helping students solve word problems, but I couldn't find a Spanish Version. So, as the saying goes, if you want something done, you just have to do it yourself!
This download includes a CUBES strategy anchor chart, Palabras Claves anchor charts for Restar y Sumar, and student version cheat sheets.
My students have greatly improved their independent problem solving based on these. I hope they are as useful for you as they have been for me!
