How are pictures A and B mathematically the same?

​

​Look at the two pictures:

• A and B are the same because they both show equal groups of dog treats.

• Both pictures show 18 dog treats.

• Both pictures show them arranged in three columns.

• The treats are the same size and shape in both pictures.

​

How are they the same?

How are pictures A and B mathematically different?

​

​Look at the two pictures:

• A and B are different because A shows 18 in 3 groups of 6, but B shows 18 in 6 groups of 3.

• Picture A shows 1 row of equal groups, but B shows 2 rows of equal groups.

• Picture B shows each group in A broken in half, so there are twice as many groups.
