The big ideaSharing equally means the same for everyone. The answer is one share.
How it works
Sharing equally means the same for everyone.
Deal the things out one at a time, round and round, until none are left.
The answer is one share: what each one gets. On the frame it fits on a single row.
Check by multiplying back: the shares together make the whole.
🍪15 cookies🧒3 friends🟰5 each
Fifteen cookies shared by three friends.Three shares of five make fifteen: multiplying back.
Example 1: 15 ÷ 3
Fifteen cookies, three friends.
Deal one at a time, round and round, until the tray is empty.
Three piles, all the same. Count one pile: it has 5.
15 ÷ 3 = 5
Check by multiplying back: 3 × 5 = 15
One share of 15 ÷ 3.
Example 2: 16 ÷ 2
Sixteen stickers, two piles.
Deal one to each pile, round and round.
Each pile has 8 stickers.
16 ÷ 2 = 8
Check: 2 × 8 = 16
One share of 16 ÷ 2.
Example 3: 30 ÷ 5
Thirty stickers go to five friends.
Slide across the beads for one friend's pile.
One row with 6 beads shows each friend's share.
30 ÷ 5 = 6
Check: 5 × 6 = 30
One share of 30 ÷ 5.
Example 4: 28 ÷ 4
Twenty-eight marbles go into four bags, the same in each.
Show one bag on the frame.
One bag holds 7 marbles.
28 ÷ 4 = 7
Check: 4 × 7 = 28
One bag of 28 ÷ 4.
Words to know
share
What one person gets when things are shared out equally.
equal
The same for everyone.
divided by
Another way to say shared by: 15 ÷ 3 is fifteen divided by three.
multiply back
Check a share by multiplying: three friends with five each make fifteen.
Watch out
The answer is one share, not the whole pile. In 15 ÷ 3 the answer is 5, what each friend gets.
Equal means the same for everyone. A bigger pile for one friend is not sharing.
Check by multiplying back, not by adding the two numbers.
One share fits on a single row of the frame.
Try it
What is 12 ÷ 3?
What is 28 ÷ 4?
Ten crackers are shared by two friends. How many does each get?
How do you check that 18 ÷ 3 = 6?
Answers: 1. 4 · 2. 7 · 3. 5 · 4. 3 × 6 = 18
Try at homeAsk a grown-up to help you share twelve crackers or grapes with two or three people. Deal them out one at a time, count one person's pile, then multiply back to check.
