In Maths this week we have looked at different ways to compose 100. We began by recognising that there were 10 tens in 100 and then made the connection that there must be 100 ones. We also looked at other denominations and established 50 x 2,  25 x 4 and 20 x 5 all composed to make 100 also. We used braining camp and 100s grids to demonstrate this effectively. Our week concluded by recognising that we could also use multiples of 10 to construct 100. For example, we used counters on the 10s frame to represent how 2 tens add 8 tens would equal 10 tens or 20 + 80 = 100. Next week we will move on to looking more in depth at complements to 100 and how we mentally calculate these.
