3rd Grade Mathematics — Multiplication and Division — God's Order in Numbers
Students will understand division as sharing equally and as the opposite of multiplication.
Division is splitting a number into equal groups. The early Christians shared everything they had with one another. Division helps us figure out how to share things fairly and equally.
If you have 12 apples and want to share them equally among 3 friends, you divide: 12 ÷ 3 = 4. Each friend gets 4 apples. Division answers the question, 'How many in each group?'
Division is the opposite of multiplication, just like subtraction is the opposite of addition. If 3 × 4 = 12, then 12 ÷ 3 = 4 and 12 ÷ 4 = 3. Knowing your times tables helps you divide!
Division can also answer, 'How many groups can I make?' If you have 20 stickers and want to put 5 in each bag, you divide: 20 ÷ 5 = 4 bags. Same operation, different question!
Sometimes things do not divide evenly. If you have 13 cookies and 4 friends, each friend gets 3 cookies with 1 left over. The leftover is called a remainder. We write it as 13 ÷ 4 = 3 R1.
Use 24 small objects. Divide them equally into 2 groups, then 3 groups, then 4 groups, then 6 groups. Write the division sentence for each. Try dividing 25 objects into 4 groups — what is the remainder?
