The purpose of this lesson is to help students develop their understanding of algebra using the patterns of multiplcation that occur on a hundreds board.  This is an effective strategy that will help students develop an understanding of multiples which is very crucial in 4th grade and above.  It also reinforces mutiplication as repeated addition.  This is also an effective strategy to use with English Language Learners, Special Educational Students and struggling learners because it provides a hands-on, interactive format for the whole class to see and participate.This lesson is also very engaging and it promotes most of the 5 C's: critical thinking, creative thinking, collaboration, communication, and citizenship.Use the following sites to look at 2 products that I have used from EAI and Didax.https://www.eaieducation.com/Product/504038/Make_a_Splash%e2%84%a2_120_Mat_Floor_Game.aspx (see image)https://www.didax.com/hip-hoppin-hundreds-mat.html 

Repeated motion is present everywhere in nature. Learn how to 'make waves' with your own movements using a motion detector to plot your position as a function of time, and try to duplicate wave patterns presented in the activity. Investigate the concept of distance versus time graphs and see how your own movement can be represented on a graph.
