Easy set up and easy implementation. This activity is a whole class activity that allows students to work in two teams, answer customary conversion questions related to length in a competitive and fun way. I have included a game board, cards, and a conversion chart. I have also included a very quick and effective way for students to remember whether to multiply and divide while they are converting. Perimeter, area, and volume problems are also included. Students will get great practice, learn to work cooperatively as a team and practice a very pesky skill.
