“My name is Max, and this is the truth./ I’m six and a half. My best friend is Ruth. / We like to solve problems all about math, / Like adding, subtracting, patterns, and graphs.” Two of Max’s nineteen rhyming adventures are perfect for the hundredth day of school: Counting Coins and A Sweet Story. Counting Coins is about counting one hundred pennies by ones, twos, fives and tens. A Sweet Story is about estimating the number of lollipops and jelly beans in the candy shop.
