## Clip Description

The National Trust created a list of exciting outdoor challenges. They called it 50 Things to do Before You’re 11¾. Challenges on the list include building a den, skimming a stone, foraging for wild food, stargazing, keeping a nature diary and playing Poohsticks.

In this fascinating clip, we are given some top tips for winning a game of Poohsticks – a game first mentioned in a book featuring Winnie-the-Pooh. In this simple game, players must drop a stick on the upstream side of a bridge. The one whose stick first appears on the downstream side, is the winner. What do you think the ‘perfect’ poohstick looks like? Watch the clip to find out.

## Quick Whiteboard Challenge

In the clip, we are shown a formula to describe the perfect poohstick. This formula uses algebra. Algebra is an area of mathematics where letters and symbols are used in place of numbers.

a = 2      b = 3        c = 4

Using the facts above, can you complete the following number sentences?

a + 5 = ?

b x a = ?

c – a = ? – 8
