TES Maths Resource of the Week
Resource author: Bgm2016
What is it?
This resource is as engaging as its title suggests! It is a unique problem, which challenges students' knowledge of straight line graphs, speed, distance, time, substitution and much more.
It may be a simple one-sided worksheet, but the discussion it provokes makes it almost as useful as a 30-slide lesson presentation.
How can it be used?
Activities like these lend themselves well to my counter technique. This works by allocating one or two counters to small groups of students. These counters can be exchanged for a teacher hint at any stage during the lesson. As they cannot ask for any additional help once the counters have been spent, pupils are encouraged to talk to one another and to really think about their question choices.
As an extra twist, why not allow them to exchange a counter for a 30-second go on Desmos? Students can use the graphing software to test out their ideas for the equations of the lines.
