It's not unusual for children to have trouble learning the multiplication facts. Fortunately, you can help if you're willing to work with your child every day. For the best results, keep drill sessions short, review learned facts frequently, and don't teach a new set of facts until your child has completely memorized the previous set. Begin by doing the following:

1. Make a set of multiplication flash cards with your child. Do not include the answers on the cards.

2. Work with one set of facts at a time (2x1, 2x2, 2x3, 2x4, etc.)

3. Next, work with the set of facts that has 2 as a second factor (1x2, 2x2, 3x2, 4x2, etc.) Remind your child that these facts are equivalent to addition doubles.

4. In the next session, work with the 5x tables. Start with 5 as the first factor (5x1, 5x2, 5x3) and then tackle 5 as the second factor (1x5, 2x5, 3x5).

5. For some children, it helps to recognize patterns when then exist within each set of facts.

6. To help your child with the 4x tables, you can teach the double and then double again approach. For example, 4x3=12 because double 3 is 6 and double again is 12; 4x4=16 because double of 4 is 8 and double again is 16, and so on.

7. To help your child with the 9x tables, teach the -1 approach. For example, 2x9=18 because 2-1 is 1 and 9-1 is 8; put them together and you get 18. Similarly, 3x9=27 because 3-1 is 2 and 9-2 is 7; put them together and you get 27.

When your child doesn't know a fact, don't tell the answer. Answers that come easily are not retained. Instead, show how to find the answer. For example, to figure out 3x4 the child can draw 3 parallel horizontal lines and 4 parallel vertical lines. Then count the intersections to find the answer.
