Two new cameos this month.
• Squound A square and a circle intersect in a 'squound'. If you know the number of objects in the square and the number of objects in the circle, how do you calculate the number of objects in the squound? Tasks are designed for early success, so this opening challenge is enticing without being too difficult. Tasks include materials so the maximum number of students can access them. You might be able to answer the intial challenge without the counters, but your students might need them. And tasks are also designed with an iceberg and this task has a beauty based around the questions How many solutions are there? and How do we know when we have found them all?. Now the task is suitable for Years 2 - 12.
• Time For Tiling This tiling pattern is within a square and involves dark square tiles on the main diagonals and light square tiles in the other positions. If I tell you the size of the square, can you tell me the number of dark tiles and the number of light tiles? The challenge can be approached through number patterns in a table, or through seeing how the tiling pattern is constructed. Both approaches lead to a generalisation (and the symbolic representation of it), so the challenge encourages the mathematician's question Can I check it another way?.
