## Color Math Tiles and Guided Math Lessons

We can use these 1″ plastic tiles in four colors to build models of math concepts, develop basic arithmetic skills and explore color and number patterns. Remember that in terms of a guided math lesson, you always want to think in terms of doing concrete activities, then pictorial activities and finally abstract activities. Spend time in small groups developing conceptual understanding as well as procedural fluency. We want our students to understand the math they are doing.

Here are some great general sites:
