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 .Students use the Equations learning object to explore algebraic and equivalent equations.
3. 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.
4. 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.

Factor Race: Begin at the starting gate with a race car. Move around the track to the finish line as you factor equations correctly. When you complete each level you earn a better race car. Ready, get it correct, Zoooooommmm! Factor Race is a game where the player must identify the binomial factors of trinomial equations. The game uses logic to develop cognitive math skills. The touch mechanic of the game engages children in a hand-on learning process, implementing kinaesthetic learning. The game incorporates mathematical problems attuned to binomial and trinomial factoring, based upon problems from textbook materials.
