An activity to work out which sport each contestant is taking part in, depending on the numbers on their vests (based on multiples of 2 and 5 and number order). Could be used as part of a sports unit or a stand-alone problem solving activity.
An activity to draw necklaces of a given length and then compare to find the longest and shortest.
We used it as part of a Royalty unit alongside practical jewellery making.
I asked the children to draw the line of the necklace first, then add their decorations by drawing, collaging etc. You could also incorporate repeating patterns or symmetry.
