Some third grade mathematicians were a little intimidated by the idea of learning division, but then they saw that it's just the opposite of multiplication! We learned that division is the same as splitting or separating a group into smaller, equal groups.
For example, there are 25 peaches in this array. The array is divided, or separated into 5 equal rows. Each row has 5 peaches. So, 25 divided by 5 equals 5. Ask your child to show you the 3 ways we can write division!
In addition, Room 221 mathematicians learned that multiplication and division are related. Therefore, we can make a fact family with multiplication and division sentences similar to making fact families with addition and subtraction sentences. The fact family for this array is:
Ask your third grade mathematician to show you another fact family!
