The Math Essentials: Speed Wheel Drills series consists of three workbooks: for Addition, for Multiplication, and for Division. Speed wheel drills are an unusual way to review math facts that is simple for students to use on their own. Students of any age who need to practice math facts should find them useful.
All three books have the same layout. Each page has an array of 12 speed wheel drills. Each of the 12 speed wheel drills has three concentric circles.
Addition speed wheel drills have the number to which other numbers will be added in the central circle, such as “+8” or “+4,” up through “+12.” The central numbers are arranged randomly on each page of drills so that students do not encounter a consistent pattern of answers they can just memorize. Each page has a speed wheel drill for each of the numbers up through 12.
Spokes extend from the central circle to divide the next two circles into 12 sections each. The second ring has the numbers 1 through 12 arranged in random order. These numbers will be added to the number in the center. The third ring has blank spaces for students to write the sum for each set of two numbers.
Multiplication speed wheel drills also use the number 1 through 12 in the center (e.g., “x 6”) surrounded by the numbers 1 through 12 in the second ring.
For division speed wheel drills, the numbers in the center are 1 through 12. However, the second ring has dividends (the numbers to be divided) up through 144, found on the wheel for dividing by 12. Students will write the answers (the quotients) in the third ring.
Each speed wheel drill has a line for recording the number of problems answered correctly and a line to record the time. So you can use these as timed drills. At the back of each book are a list of the math facts and their answers but not answers for each individual speed wheel drill. Someone who knows the math facts should check the answers, since students might not notice their own errors.
There are 1,440 speed wheel drills in each workbook. Younger students might complete one or two wheels at a time, while older students might do more. Since the central numbers don’t repeat, it doesn’t hurt to have previously completed wheels visible on the page.
