First, familiarise yourself with the terms Pattern Recognition and Decomposition, by watching Part 5 of 鈥淒elve in, for twelve min!鈥� (Video linked above).

Give the children the 鈥楶attern Recognition鈥� scratch project. Children have to find different ways to reduce the amount of code that is repeated.

I鈥檝e included 3 different solutions;

1. Broadcast (Not always the best solution, please see Part 6 of 鈥淒elve in, for twelve min!鈥� on 鈥榗oncurrency and dependency鈥� )
2. Make a Block function (more advanced when you include number input)
3. Using Make a block, selection and repetition (You can see how much smoother the code runs straight away)

Please let me know how you get on!

Cheers
