A2.2 Core Plenary
Here is an equation generator.
To fill each box, throw a dice.
Make some equations and
solve them to find what x equals.
Challenge
What is the largest possible value of x?
What is the smallest possible value of x?
Preamble
A simple device to allow pupils to practise solving simple linear equations. The activity can be worked on individually or in small groups. Ask pupils to keep a record of all the equations generated, with a view to looking at some of the more interesting ones with the whole class.
The first part of the challenge should be accessible to most pupils. The second part may require more guidance and a reminder about negative numbers.
Possible content
Solving simple linear equations.
Resources
Dice (can have any number of sides though the solution is given for six-sided dice).
Solutions/Notes
Largest solution is x = 12 (equation is 1x – 6 = 6). Smallest solution is x = −5 (equation is 1x + 6 = 1).
Some pupils may think the smallest solution is x = 0 (produced by many equations).
