Starting Algebra with Year 8, we spend a couple of lessons on various “algebraic techniques”. I’ve been trying to find some activities which provide a little more engagement. I created “The Land of Algerb“ to explain multiplying pronumerals.
Using a story and a coloured worksheet worked surprisingly well. I don’t know yet if the story has helped my class understand the technique, but they all actively completed the activity keen to ensure their own story way correct.
In the land of Algerb there were two kingdoms, the kingdom of 2x and the kingdom of 3y. The King of 3y and the Queen of 2x both wanted to increase their lands.
The King of 3y and the Queen of 2x took their explorers to the undiscovered land.
Whilst in this new land, the people mingled.
The numbers met the numbers and the letters met the letters.
The two kingdoms became one, the numbers multiplied, but the letters stayed the same.
A new nation had been formed, each nation’s numbers had been made bigger. But the letters of each nation were still distinctive. The xs from the 2x kingdom and the ys from the nation of 3y.
