In this interactive math game, students will fluently solve multiplication problems while popping the balloons in order from smallest answer to largest answer.

This video lesson examines the meaning of the equal sign as we work to solve unknowns in multiplication and division equations.

This tool, created by Science NetLinks, challenges students to consider mathematical equations to get from one number to another in a math maze. Students use a series of addition, subtraction, and multiplication equations to reach their goal.

This lesson is from Tools for NC Teachers. Students explore factors, multiples, and the concepts of prime and composite. This is remixable.
