3 times table in real life: triangle corners

Use triangle corners to make the 3 times table concrete, funny and memorable.

Quick answer

3 times table in real life: triangle corners helps you learn the 3 times table by counting the corners of triangles in everyday life. Every triangle has 3 corners, so 1 triangle = 3 corners, 2 triangles = 6 corners, and so on.

Learning outcome

By the end of this page, you will be able to count and multiply by 3 using triangle corners in real life, like when you see 3 triangles, 4 triangles, or more. Success signs:
  • You can count 3 corners on each triangle
  • You can say how many corners there are in 2 triangles
  • You can use multiplication to find how many corners in 5 triangles
  • You can spot triangles around you and count their corners

Why this matters

Learning the 3 times table helps you in many ways:
  • When you play football and count how many players are on a team (3 players on a triangle team)
  • When you make art with triangles
  • When you build with blocks or LEGO
  • When you share food, like 3 slices of pizza for each of 4 friends
  • When you count things in groups of 3, like 3 legs on a chair or 3 wheels on a tricycle

How it works

Every triangle has exactly 3 corners.
  • 1 triangle = 3 corners
  • 2 triangles = 6 corners
  • 3 triangles = 9 corners
  • 4 triangles = 12 corners
You can count by 3s: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36. You can also add 3 each time: 3 + 3 = 6, 6 + 3 = 9, 9 + 3 = 12.

Examples you can see

Here are some fun examples using triangles and their corners: Triangle corners and 3 times table
Number of triangles Number of corners Calculation
1 3 1 × 3 = 3
2 6 2 × 3 = 6
3 9 3 × 3 = 9
4 12 4 × 3 = 12
5 15 5 × 3 = 15
6 18 6 × 3 = 18
7 21 7 × 3 = 21
8 24 8 × 3 = 24
9 27 9 × 3 = 27
10 30 10 × 3 = 30
11 33 11 × 3 = 33
12 36 12 × 3 = 36

Try it as a mini adventure

Triangle Hunt Adventure You are going on a special hunt around your house or garden to find triangles.
  • 1st time: Find 1 triangle (like a slice of pizza or a roof)
  • 2nd time: Find 2 triangles (like 2 toy cars with triangular wheels)
  • 3rd time: Find 3 triangles (like a triangle-shaped cookie cutter)
  • 4th time: Find 4 triangles (like a group of 4 triangle flags)
  • 5th time: Find 5 triangles (like 5 triangular stickers)
Now count how many corners you found in total.
  • 1 triangle = 3 corners
  • 2 triangles = 6 corners
  • 3 triangles = 9 corners
  • 4 triangles = 12 corners
  • 5 triangles = 15 corners
Try to find 6 triangles next time and count how many corners you get.

Common mistakes

  • Mistake: Thinking 3 × 3 = 9, but forgetting that 3 × 3 = 9 (this is actually correct!)
    • Why it happens: Some children mix up multiplication with addition
    • Fix: Use your hands to count 3 groups of 3 fingers, or draw 3 triangles with 3 corners each
  • Mistake: Counting the sides instead of the corners of a triangle
    • Why it happens: Children might not know the difference between corners and sides
    • Fix: Point to each corner with your finger and say "1, 2, 3" for the 3 corners
  • Mistake: Confusing 3 × 4 with 3 × 3
    • Why it happens: Mixing up the numbers when counting
    • Fix: Use the triangle hunt to keep track of how many triangles you are counting

Parent and carer guide

Parents and carers, here's how to help your child learn the 3 times table with triangle corners:
  • Ask your child to find triangles around the house (like a roof, a slice of pizza, or a toy)
  • Count the corners together with your child
  • Use a simple chant: "3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36"
  • Draw triangles on paper and label how many corners each has
  • Play the triangle hunt game with 3, 4, 5 triangles to make it fun
  • Try to find real-life examples like 3 wheels on a tricycle or 3 legs on a chair
Remember: Don’t worry if your child gets confused at first. It takes time to learn. Be patient and keep playing with triangles!

FAQ

What is a triangle?

A triangle is a shape with 3 sides and 3 corners.

Why do triangles have 3 corners?

Because a triangle is made of 3 straight lines that meet at 3 points, which are the corners.

Can I use triangles to learn other times tables?

Yes! You can use triangles to learn 3 times table, and also try 2 times table (sides of a triangle) or 6 times table (if you count sides and corners together).

What are some real-life triangles?

Real-life triangles include roofs, slices of pizza, traffic signs, and triangular stickers.

How can I remember the 3 times table?

Count by 3s: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36. You can also use the triangle hunt to help!
