This video is an overview of how students can use Speed Squares in the classroom using interval practice and folding in to master their X2 or 2X multiplication facts and fluency. Interval practice and folding in are both researched based strategies. The video also shows how teachers and parents can differentiate the student's learning if they are struggling or need enrichment. Speed Squares are better than flash cards. I have permission from Speed Squares to video and present their product. I will produce more how to videos in the future. Speed Squares can be purchased at www,speedsquares.org Speed Squares is a box containing 80 color coded 2 in. by 2 in. rounded gaming cards that replace all flash cards. The 80 cards have graphics on both sides and have multiple uses. Speed Squares LLC is located in Hiram, Georgia.
