During one of our maths lessons we had to work in groups of 4 to solve this problem. We were given one sheet of paper with the numbers 1-100 on it. We then each had a different coloured pen and had to circle our numbers.
The catch was that we only have 3 minutes and we had to circle the numbers in order. Each person had a number 1, 2, 3, and 4 then we had to keep using the same pattern of people to keep the numbers going up to 100. We were interested to find out there was a pattern we found at the end. Here are some photos from us trying to figure out the quickest way to do it. We had so much fun completing this activity.
