We often talk of dividing as being the reverse of multiplying, and indeed when dividing fractions this is the case. The way you divide fractions is very similar to the way fractions are multiplied with a simple twist in the middle.
Using times tables is simple. Practice multiplying the 2’s, 5’s, and 10s first, then the doubles (6 x 6, 7 x 7, 8 x 8). Next, move to each of the fact families: 3’s, 4’s, 6’s, 7s, 8’s, 9’s, 11’s, and 12’s. Start by doing one sheet and see how long it takes you to complete it. Do not worry about how many right or wrong answers you get the first time you complete a worksheet. You will get faster as you become better at multiplying. Do not move to a different fact family without first mastering the previous one.
Dividing numbers. After your child grasps the concept of dividing and the relationship with multiplication you can start working with numbers. Be sure your child is familiar with the format and signs for division. With the concept grasped, teaching division will become more about guided practice to help your child to become familiar with the division operation (although it’s really going to be a different type of multiplication practice.) Start by practicing division by 1, 2 and 3 and then gradually move up to 9. Use the worksheets to help.
If the two values being subtracted are mixed fractions, it is often easier to turn them into improper fractions to perform the subtraction. This avoids any kind regrouping or borrowing from the minuend fraction if the numerator in the subtrahend is larger.
