This week we have been exploring the patterns made by multiples of 2, 3, 5 and 10. Outside in the garden we noticed that some leaves seem to grow in pairs, but others do not. We carefully counted how many leaves were on a 30 cm strip of willow then checked using 100 squares to see if the total was a multiple of 2, 5 or 10. Today we found out that if you find all the multiples of 3 on a 100 square, the pattern of the numbers goes odd, even, odd, even and so on. I wonder which other patterns we will find as we continue to explore these numbers!
