__DO NOT SPEND MORE THAN 10 MINUTES ON THIS ACTIVITY__

__WALT find the area of triangles__

**Recap**

- The area of a triangle is always half the area of a rectangle that has the same height and width.

- This is because a triangle can always fit into a rectangle twice, no matter the shape of the triangle.

- Formula for working out the area of a triangle is:

(base x height) ÷ 2

You can also write the formula as:

½ x base x height

They both give you the exact same answer since multiplying by a half is the same as dividing by 2.

__Challenges __

- Today I would like everyone to watch the video and follow the instructions and activities. The video will take you through the activities step by step.

- Pause the video so you can give yourself enough time to work out each question.

- You will need to worksheet with you when you watch the video because you will answer some of the questions as you go.

- Try to complete as many questions as you can. The questions get harder as you progress through the sheet. See how far you can go!

**IMPORTANT **

**If you find this formula difficult, ½ x base x height **

**Then try it this way round (base x height) ÷ 2 **

**Some people find it easier!**
