Adding two 2 digit numbers
To develop confident mental skills, children are encouraged to add the 10s numbers, then to add the units/ones numbers.
eg 47 + 26
40 + 20 = 60 add the '10s' numbers
7 + 6 = 13 add the '1s' numbers
60 + 13= 73 put the totals together to find the final answer
Perhaps practise/model a few on paper or a white board.
Subtracting 2 digit numbers
To develop confident mental skills when subtracting, children are encouraged to find the different between two 2 digit numbers.
An interactive version of this has been allocated to everyone in Year 2 in their Active Learn profile.
Different examples can be practised using the number tool.
The children can draw a line and put the smaller number at the start and the larger number at the end. In school we use a frog to jump on. Frog starts at the smaller number 26 and hops on to the next multiple of 10, 30 is then marked on the line. A hop from 30 to the 32 is then made.
What has happened? To find the difference these jumps were made
Children may need to be reminded that subtraction isn't only 'taking away'.
This method is also very useful when working out change.
Multiplication and Division
Children are encouraged to apply their knowledge of multiplication and division in word challenges/problems.
They need to:
decide what they are being asked to find out
what coin is involved
what step they count in (that coin)
what the answer is
