ug-of-war, but they'll need to use some everyday math to figure out how to make teams that are equal. As Mouse looks at various solutions she is not sure what it means to be equal. Nothing works until Mouse starts to think about it mathematically and divides the teams based on weight. Wonderful illustrations capture Mouse and her animal friends from whiskers to tails as they work to measure and equalize their teams based on size, weight, and effort. A perfect addition to any STEM/STEAM collection that shows readers how math can be used in everyday problem solving.
