Year 5 and 6 Problem Solving |
|||
|
These children have been set some problems to solve. They
have been asked to decide which operations they need to use – addition,
subtraction, multiplication or division. Some of the problems may involve several
steps each needing a different operation. They have been encouraged to discuss the problems and
explain to each other the processes they think should be used |
|

|
The problems they were asked to solve were like this
one – The local scouts group wants to take 208 children and
25 adults on a trip to a theme park as a summer treat. The coaches seat 53. How many coaches will they need to
book for the trip? |
||
|
The children recorded their ideas in rough books to help
them decide the best way to solve the problems they had been set. Some off them applied the grid method of multiplication to
help them solve the problem. They were then asked to check their calculations by using
the inverse method, that is use division to check multiplication and addition
to check subtraction and so on. |

Can you spot the mistake in the calculation that this
child spotted when he checked his work? |
