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

    • Chains is a game that involves placing cubes on a row of cells. Each block placed scores at least one point, but if it can be placed to make a chain of blocks the score becomes the number of blocks in the chain. The challenges begin with finding the highest and lowest possible score. What about the scores between; are they possible? And what happens if we change the length of the playing board? Interesting number patterns is the answer to that question.
    • Angle Estimation uses a Rotagram to estimate angles and provides two protractors (5 and 1) to check the estimates. The Rotagram reinforces the concept of an angle being the shape made by two rays with a common starting point and the measurement of an angle being the amount of turn between the rays. Students practise both estimating and measuring and the iceberg is opened up when they discover how to use the Rotagram to add angles.
