In Maths this week we have been comparing numbers to 20. We have been finding the difference between 2 numbers between 11 and 20, and then explaining how we know. For example- We know 11 is less than 15, we can see with the cubes they both have a 10 but 11 has 1 extra, where as 15 has 5 extra. We also talked about how we could make the numbers/towers the same by adding and subtracting.
