Here we have two sets of worksheets on adding up the cost of buying Christmas tree decorations. The first set deals with multiples of 10p and is therefore much easier. Perhaps the hardest part is matching the images to the cost and some children will find it helpful to make jottings next to the images. The second set deals with far more awkward amounts such as £1.99 and £1.49. Probably the best technique to use with these is to round the amounts up to the nearest whole pound or 50p, add them and adjust at the end. This is certainly the way I did it whilst working the answers out! It is very tricky otherwise. With both these sets of questions it is well worth taking a little time to ask children how they set about them and the techniques they used to work out the answers.
