The concept of multiplication is our current unit of study in math. Multiplication is repeated addition. We have also learned about arrays.
Our
math glossary defines an array as: An arrangement of objects in rows and columns.
ROWS go across.

Here are some arrays we found around our school. Notice how we used synonyms for the word

The next few arrays are special. Both of the factors are the same and they make a square. We call them the square products!

Here are two arrays of yellow and orange zinias that Mrs. Yollis planted.
I see 3 rows of 2 on the left.
I see 3 rows of three on the right.
How many yellow and orange zinnias?
Hint: Use multiplication
and addition!
*
*
*
Answer:
(3 x 2) + (3 x 3)
6 + 9 = 15 yellow and orange zinnias!
