Brilliant extension activity for looking at plans and elevations and 3-D visualisation skills. Build up a shape so that it matches the plan and elevations and the light turns yellow, then remove uneccessary blocks to find the optimum solution using the least number of blocks to turn the light green. The Notebook file contains a possible solution for each one (there is more than one way to solve each one).

Gives a brief history of the calendar and the introduction of leap years and looks at some maths related to this. PLEASE REVIEW / COMMENT. NB: Notebook file was created on version 10 and does not display properly on the new version 11.

Lots and lots of activities and investigations based around number sequences. PLEASE REVIEW / COMMENT. They are not fully worked lesson plans, but rather some ideas for activities.

A fun worksheet activity involving patterns in the digital roots of a multiplication grid. PLEASE REVIEW / COMMENT. Print off 'Vedic square - blank', cut into three, so that each student has two squares, one to complete as a multiplication grid and one to complete as a Vedic square (by finding the digital root of each number in the multiplication grid). When they have completed these, hand out either version of 'Vedic square - completed' (better on A3) for them to draw the patterns.
