Examples you can see

Try it as a mini adventure

1. First, look around your house and count how many people live there
2. Each person has 1 pair of shoes
3. Use multiplication to find the total number of shoes
4. 4th time: ? pairs of shoes = ? × 2 = ? shoes
5. 5th time: ? pairs of shoes = ? × 2 = ? shoes
6. 6th time: ? pairs of shoes = ? × 2 = ? shoes
7. 7th time: ? pairs of shoes = ? × 2 = ? shoes
8. 8th time: ? pairs of shoes = ? × 2 = ? shoes
9. 9th time: ? pairs of shoes = ? × 2 = ? shoes
10. 10th time: ? pairs of shoes = ? × 2 = ? shoes

• Number of people = 4
• Each person has 1 pair of shoes
• Total pairs = 4
• Each pair = 2 shoes
• 4 × 2 = 8 shoes

Common mistakes

• Mistake: Counting pairs as 1 shoe instead of 2
  Why it happens: Not remembering that a pair means 2 items
  Fix: Always remember that 1 pair = 2 shoes
• Mistake: Forgetting to multiply by 2
  Why it happens: Thinking you only need to count the pairs
  Fix: Remember that pairs mean 2 shoes, so multiply by 2
• Mistake: Adding instead of multiplying
  Why it happens: Not understanding that multiplication is repeated addition
  Fix: Practice counting by 2s to see how multiplication works

Parent and carer guide

• Using real shoes to practice counting pairs
• Playing "How many shoes?" games during daily routines
• Encouraging children to count their own shoes
• Using multiplication to solve everyday problems like "How many socks do we need for 5 people?"
• Practicing skip counting by 2s to build multiplication skills
• Looking for other pairs in the house (gloves, socks, scissors, etc.) to multiply
• Being patient if children make mistakes - this is part of learning

FAQ

What is multiplication hiding in pairs of shoes?

Multiplication hiding in pairs of shoes is a way to quickly count shoes by remembering that 1 pair equals 2 shoes, then multiplying the number of pairs by 2.

Why do we multiply by 2 when counting pairs?

We multiply by 2 because each pair of shoes contains exactly 2 individual shoes. So if you have 3 pairs, you have 3 groups of 2 shoes each.

Can I use this method for other things that come in pairs?

Yes! You can use this method for socks, gloves, scissors, earrings, or any items that come in pairs. Just remember to multiply by 2.

How can I practice this at home?

You can practice by counting your own shoes, socks, or gloves and multiplying by 2. You can also play games where you guess how many pairs of items there are and then multiply to find the total.

What if I forget the multiplication facts?

You can count by 2s to help you remember: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24. You can also use objects like counters or blocks to show the groups.
