These exercises and activities are for students to use independently of the teacher to practise number properties.
solve linear equations with fractions.
use appropriate forms of the equation to solve for x.
use a range of add/sub strategies to solve linear equations.
Addition and Subtraction, AP (Stage 8)
Use a range of number strategies for solving addition and subtraction problems with fractions.
Exercise 1 – Students are not required to know any methods of solving equations to be able to solve these problems. The requirement is that they immediately write the equation in a form that tells them the calculation they need to do (for learning this skill with whole numbers see Task: Strategic Solving Part I). Students will be required to select an appropriate Add / Sub strategy in order to calculate x.
Exercise 1
Asks students to solve linear equations involving fractions. Students need to rearrange the equation and solve for x. To solve for x students will need to convert fractions to a common denominator.
Exercise 2:
Asks students to write word problems for the equations in Exercise 2.Exercise 2 could be used as homework.
