Stage 4 - linear equations
- solve linear equations
Activities to support the strategies
1. The teacher provides a number of cards which demonstrate the use of various methods to solve linear equations using symbols and words.
Students and the teacher discuss the links and use the vocabulary needed to express the equations in words.
In pairs students arrange sequence cards to demonstrate the solution of equations.
Discuss or write explanations to justify their arrangements, e.g.
2. The teacher provides a number of cards which demonstrate the solution of linear equations using symbols and words. In pairs, students arrange the correct sequence to demonstrate the solution of the equation.
3. Pairs of students write the steps for solving inequalities on cardboard or paper, cut up and shuffle the cards, then challenge other pairs of students to place the solution steps in order.
