Whole Number Exponents: Teddy Bear Box

Five questions—multiple-choice, fill in the blank, and discussion—make up an interactive that challenges scholars to mail a teddy bear using the smallest box possible without squishing it. A box with movable sides allows mathematicians to estimate the measurements based on the size of a teddy bear picture. The tool and measurements are used to answer problems.
