If the Tens cannot be divided without a remainder then the number must be broken into mulitples into which the divider can be dived. eg. 3 x 10 = 30 > 54 = 30 + 24

68 ÷ 4 = → (40 ÷ 4) = 10 → (28 ÷ 4) = 7

10 + 7 = 17

If the Tens cannot be divided without a remainder then the number must be broken into mulitples into which the divider can be dived. eg. 4 x 10 = 40 > 68 = 40 + 28

Relation between addition and subtraction.

Study the example.

Addition and subtraction are inverse (opposite) operations. It means that what you do with addition or subtraction, you can undo by using the opposite operation e.g. 10 - 3 = 7 can be undone by saying 7 + 3 = 10

Multiply and divide are also inverse.operations.eg. 10 x 3 = 30 can be undone by saying 30 ÷ 3 = 10

Analogue & Digital Time

We get Analogue and Digital Time

Analogue Time has two “arms” they show hours and minutes. The short arm shows hours and the long arm shows minutes. These arms always move to the right and the clock is divided into 12 hours. Digital time shows the time using numbers. Digital time shows hours on the left and minutes on the right side of the dots. Thus, the left is the short “arm” and the right is the “long” arm on an analogue clock. Some digital watches are divided into 12 hours (thus repeats twice a day) others are divided into 24 hours.


Show the time as digital and analogue time.

62 x 4 =

53 x 3 =

42 x 5 =

46 x 3 = Numbers can also be → (40 x 3) + (6 x 3) written next to each other

Divide 2-digit numbers using a method.

45 ÷ 3 =

20 ÷ 4 =

54 ÷ 3 =

68 ÷ 4 =

57 ÷ 3 = → (30 ÷ 3) = 10 → (27 ÷ 3) = 9

10 + 9 = 19

64 ÷ 4 = → (40 ÷ 4) = 10 → (24 ÷ 4) = 6

10 + 6 = 16

If the Tens cannot be divided without a remainder then the number must be broken into mulitples into which the divider can be dived. eg. 3 x 10 = 30 > 57 - 30 = 27

If the Tens cannot be divided without a remainder then the number must be broken into mulitples into which the divider can be dived. eg. 4 x 10 = 40 > 64 – 40 = 24
