## 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.

## 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.
