    • Well done 1S for completing the maths challenge. I am really proud of you all. We need to invite Mrs. Carman to our maths lesson so she can learn to count in 10s correctly.

  2. Count in 10s from 13 = 23,33,43,53,63,73,83,93,103,113,123,133,143,153,163,173,183,193,203,213,223,233,243,253,263,273,283,293,303.

    The difference between 32 and 21 is 11.
    39+21= 60

    30/10=3
    3*10= 30
    10*3= 30
    27/3= 9
    32/4= 8
