Star Sums

Can you make as many different calculations as you can using the numbers in the star.
Think about the different types of calculations, can you do the calculation the opposite way round? So 1+4 then 4 + 1. Also try to work methodically and logically through the numbers.
Eg Do all the addition first. Also work through the numbers eg 1+2,2+1, 1+3,3+1,1+4,4+1,2+3,3+2,2+4,4+2,3+4,4+3.
What other operations can you do? eg subtraction, multiplication and division.
You can then extend the maths investigation by doing other stars with more numbers.

Mosaic Picture

Image
Make a mosaic picture. You could use coloured paper for the mosaic pieces. Either tear up or practice cutting skills and cut coloured paper up. Use a piece of coloured card for the background. Black looks good. Decide what the picture will be in the middle. Pick two colours for the border and alternate the pieces. Place on card first then glue down. Create the picture in the centre. Could be a flower, animal, sport related, initials, a rainbow, football etc Glue central picture down when happy with picture. Then choose one or two similar colours  to fill in the background. Glue pieces down. We used painted lasagne pasta (which was out of date) which we've had in the craft cupboard for over a year! Paint the lasagne pasta sheets different colours, leave to dry, break up into pieces once dry and place in zip lock plastic bags or tubs.
