1. Click once on the screen to see 1 group of ten.

2. Click a second time on the screen to see 2 ones.

One bowl will feed 4 dogs. Click once on the screen to see the dogs at their bowl.

12 – 4

Use one more bowl to feed 4 more dogs. Click once on the screen to see these dogs at their bowl.

12 - 4 - 4

Use one more bowl to feed 4 more dogs. Click once on the screen to see these dogs at their bowl.

12 - 4 - 4 - 4

There are no dogs left in the barn. We subtracted 3 groups of 4 dogs.

12 - 4 - 4 - 4 = 0

Farmer Jones will need to use 3 bowls to feed his dogs.

12 - 4 - 4 - 4 = 0
