Let’s get ready to limbo! How low can you go? In order to be good at limbo, it’s important to be flexible. 2020 Arkansas Teacher of the Year, Joel Lookadoo, shows students that just as it is important to be flexible when playing limbo, it is important to be flexible when solving math problems. The worksheet that accompanies this video provides students the opportunity to practice using computational strategies to solve addition and subtraction problems with unknowns in all places.
