Young learners learn best when activities last five to ten minutes, before they drift off-task. The 10 Minutes a Day series takes this research to heart, providing quick math exercises for children — perfect for those time-to-fill moments at home, and based on one of the best and most effective learning strategies: little and often. Each book includes a ten-minute timer, beat the clock exercises, and easily photocopied pages, as well as tips, guidance, and answers for parents. In order to align with the Common Core State Standards, in 10 Minutes a Day: Math Fourth Grade children can develop an understanding of multi-digit multiplication, addition and subtraction of fractions with common denominators, understand concepts of angles, solve word problems, and more to build math skills.
