What is mixed math? It’s a surprise at every turn of the page. You don’t know what will be the next problem to solve, and that makes the game very entertaining. If you want to bond with your fourth grader, then you better get a copy of this activity book. Start with volume 1 and complete the collection until volume 3. Have fun!
