Miss Robinson’s maths group have been developing their knowledge and addition skills. They have been practicing their number bonds and adding numbers to 10 and 20. They have learnt that if they know 2 + 7 = 9 then 20 and 70 = 90. They are now learning how to work out sums using partitioning (splitting it into tens and ones) e.g. 24 + 32 = 56.
