Memorizing addition facts is not only challenging, but success-oriented and fun with this five-minutes-a-day system. Students work through a series of daily timed tests at their own rate, beginning with 0-1, 2, 3, 0-3 etc., mastering each one before proceeding to the next. Math whiz kids are constantly challenged, while students having difficulty are given the time they need to master and "overlearn" the facts. Besides worksheets and answer keys, this booklet has personal flash card masters, forms for folders and record-keeping, and additional games and activities. 89 pages, paperback, 8 1/2"x11".
