Now there’s a way to combine students’ love of speed with multiplication. Welcome to Speedy Math Practice—40 super-fun practice pages for students to complete in a race against the clock! Each page features 30 basic multiplication problems in a spiral “racetrack.” This engaging format motivates students to improve their score with every race—leading to automaticity with multiplication facts. Automaticity not only gives students more confidence in their math abilities, but it also allows teachers to spend more time on higher-level math content. The National Council for Teachers of Mathematics (NCTM) stresses the importance of computational fluency in Principles and Standards for School Mathematics (NCTM, 2000). Students in grades 3–5 “should develop fluency with basic number combinations for multiplication and division,” and “should be able to solve many problems mentally.” The math races in this book provide students with the repeated practice they need to help them master the times table. This mastery builds the foundation for computational fluency in multiplication, which will help them on homework, on standardized tests, and in real-life applications. HOW TO USE THIS BOOK The 40 reproducible practice pages in this book are arranged in order of difficulty, starting with races that focus on one number at a time—from 1 to 10—and moving on to mixed practice of facts from 1 to 12. There are many ways you can use these practice pages: for individual practice, small groups, or whole class activities. Choose a page with an appropriate level of difficulty for your students. Once you have explained the purpose of the race, use a stopwatch, egg timer, or classroom clock to time students as they complete as many problems as they can in a five-minute period (or another amount of time). When time is up, invite students to check their own papers. Explain that they should award one point for each correct answer. Once they tally their score, students can fill in the chart at the bottom of the page. Give students each a copy of the Success Chart on page 5 so they can show their progress on all 40 races. Show them how to shade the bar graph with the number of problems they answered correctly on each race. To help students improve their score, you might have them make flash cards of the problems they solved incorrectly before moving on to the next race. By the time students have finished all the races in this book, they will have had repeated practice with basic number combinations in multiplication. Mastering the basic number combinations will allow students to mentally compute more difficult problems with greater ease and accuracy. In the end, students will remember the fun they had speeding their way around the multiplication racetrack, while you’ll know the distance they’ve traveled on the way to automaticity and success in math!
