We worked in twos or threes to see how quickly we could put the numbers back onto a 100 grid.
We found there are many ways to do it, but some strategies are quicker than others.
Starting from 1 and hunting for the next numbers in order took far too long!
Using what we know about number patterns in rows and columns was quicker.
What patterns might you use to do this quickly?
