My S3 class have been learning how to solve simultaneous equations by elimination this week.
I set this problem for the class:
While this is not the most realistic of problems, it allowed the pupils to consider solutions in a familiar context. There were a few different methods used. Most tried trial and error but a few started with 20 chickens 80 legs and 1 pig 4 legs then adjusted the number of chickens until there were 30 heads.
After practicing the mechanics of solving simultaneous equations by elimination a few in the class were asking if next lesson we could do something more fun.
I wanted to provide an activity that would allow pupils to work together in a fun way that still allowed each pupil to practice solving simultaneous equations as an individual.
So I declared WAR! Continue reading
