In maths today, the children used concrete apparatus to find one more and one less than a number to 50. They recognised that they could use their knowledge of numbers to 10 to support their understanding (1 more than 6 is 7 so 1 more than 36 is 37) and began to use a 0-50 grid to calculate their answers. The mastery group had to utilise their knowledge to piece together a 0-50 grid that had been cut into different shaped pieces. They loved solving this problem!
