Sometimes a child in a story makes a guess, and the reader checks it. This 3rd grade checking reasonable estimates worksheet has two-step problems, labeled a and b. In a, Joice bakes 24 muffins, keeps 3 and shares the rest between 2 friends, and she guesses that each friend gets about 10. In b, Peter has 256 dimes, and his brother borrows half of them, and then Peter guesses that about 120 dimes are left. Your child solves each problem and then decides if the estimate is good. A girl walks on the right, while a boy stands next to a piggy bank. Page two explains both answers like a worked example.
