• Tasks of the Month
Two new cameos this month.
The Task Cameo Content Finder has been updated to include these tasks.

• Guessing Colours Game Count a total number of discs (in this case 15) using five colours and any number of each to make the total. Hide them in an opaque bag. Students take turns to select a disc from the bag, but first they each have to guess which colour will come out. A points scoring system is involved and a running total of points is kept for each player until all the discs are removed. The game involves simple addition and subtraction, may include negative numbers and is an excellent experience of chance events and sample space.
• The Hole In The Triangle appears to make the same size triangle in two different ways with the same pieces. The twist is that one of the triangles clearly has an area one square bigger than the other. It just can't be, but only mathematics can help us understand how we are being tricked and why the apparent difference is exactly one square unit of area.
