Students have to choose the correct operation to solve each problem, which can involve radius, diameter, circumference and area.
Students can also do an investigation to discover that for any circle, circumference divided by diameter is always about 3.14. Neat activity!
Take a starting number and apply a set of instructions to it to achieve a finishing number.
Click create to generate a new start number and instructions. The start number will not appear. You can choose whether to show the start number or the answer. Showing the answer modifies the puzzle so that students have to do the inverse of the instructions to find the start number.
A timer can be applied. The length of time available for each instruction can be adjusted. When the length of time has passed a light appears below the instruction to show the students that they should move on.
This interactive resource is useful for demonstrating the volume of cubes and cuboids.
A neat visual way to find the LCM (lowest common multiple) of two numbers.
