1 - Getting Started ~3 mins
These three coins are gold. They are worth far more than the small brown 1c and the other small cent coins you already know.
One of them is worth as much as fifty of the little 1c coins. Which do you think it is?
2 - Watch and Notice ~10 mins
Look at each tray. The gold coin matches a pile of smaller coins: same amount.
Ten 1c = one 10c
Two 10c = one 20c
Five 10c = one 50c
3 - Try It Together ~8 mins
One pupil at a time comes to the board. Listen for the gold coin, then find it and put it in the tray. Everyone else watches and agrees.
We will find 10c, then 20c, then 50c. After each find, the class reads the number on the coin. At the end we say which of the three is worth the most.
Find the gold coins
4 - Write the Three Coins in Your Copy ~3 mins
In your maths copy, write the three bigger coins and what each matches:
- 10c = ten 1c
- 20c = two 10c
- 50c = five 10c (fifty 1c)
