Listed below are three strategies taken from the first 16 pages of Five Times Five is Not Ten.
Explore these with your children and try and try the practice exercises on the worksheets.
1 Group
Direct your child to use manipulatives (e.g. counters, crayons, buttons, etc.) to show 1 group of 1, 1 group of 2, 1 group of 4, 1 group of 9, and so on.
Use this worksheet to practice 1 Group
Use the worksheets below for more practice with 1 Group combined with addition and subtraction.
The practice pages may include addition and/or subtraction facts mixed with the multiplication facts. Direct attention to the signs, and explain and show with manipulatives that these signs mean different things.
4 x 1, 4 + 1, 4 – 1 or 7 x 3, 7 + 3, 7 – 3

Doubles
Your child needs to know the answers to the Doubles addition facts before asking them to learn the Doubles multiplication facts.
Direct your child to use manipulatives (e.g. counters, crayons, buttons, etc.) to show 2 groups of 2. Hold out your two hands, palms up, and direct your child to place 1 group of 2 in each hand. Put your two hands together, and have your child count how many there are. Note that this is the same as doubling or adding 2 + 2. Do the same for 2 groups of 3 = the Double 3 + 3, 2 groups of 4 = the Double 4 + 4, and 2 groups of 5 = the Double 5 + 5. This is counting by 2s.
