  1. Number bonds to 10:
    0+10=10, 1+9=10, 2+8=10, 3+7=10, 4+6=10, 5+5=10

    Number bonds to 20:
    0+20=20, 1+19=20, 2+18=20, 3+17=20, 4+16=20, 5+15=20

    Number bonds to 100:
    10+90=100, 20+80=100, 30+70=100, 40+60=100, 50+50=100

    what is 10 more than these numbers?
    21+10= 31
    44+10= 54
    39+10= 49
    65+10= 75
    54+10= 64

    I am now confident with the number bonds to 10, 20 and 100.

  2. 1 Red Maths:

    Head Teacher Question (10 more)

    21 + 10 = 31.
    44 + 10 = 54.
    39 + 10 = 49.
    65 + 10 = 75.
    54 + 10 = 64.

    My Number bond of 10, 20 and 100.

    0 + 10 = 10
    1 + 9 = 10
    2 + 8 = 10
    3 + 7 = 10
    4 + 6 = 10
    5 + 5 = 10
    4 + 6 = 10
    3 + 7 = 10
    2 + 8 = 10
    1 + 9 = 10

    0 + 20 = 20
    1 + 19 = 20

    3 + 17 = 20
    4 + 16 = 20
    5 + 15 = 20
    6 + 14 = 20
    7 + 13 = 20
    8 + 12 = 20
    9 + 11 = 20
    10 + 10 = 20

    100 + 0 = 100
    90 + 10 = 100
    80 + 20 = 100
    70 + 30 = 100
    60 + 40 = 100
    50 + 50 = 100
    40 + 60 = 100
    30 + 70 = 100
    20 + 80 = 100
    10 + 90 = 100
    0 + 100 = 100
