Strike it out puzzle.
Saturday 20th April | 2 comments
In Maths we have been challenging ourselves with this puzzle, which also helps us practise addition and subtraction.
The picture below gives you the instructions for a game but we used the same idea as a puzzle, trying to work out how you could follow these instructions to cross out all the numbers except for one. Next week we will aim to post some videos to show you how we achieved this. Can you create a numberline which would mean that you could do the puzzle and have no numbers left?
You can also play the game interactively online at http://nrich.maths.org/6589
