# Strategic Solving Part IV

Achievement Objectives:

Achievement Objective: NA5-3: Understand operations on fractions, decimals, percentages, and integers.
AO elaboration and other teaching resources
Achievement Objective: NA4-7: Form and solve simple linear equations.
AO elaboration and other teaching resources

Purpose:

These exercises and activities are for students to use independently of the teacher to practise number properties.

Specific Learning Outcomes:

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.

Description of mathematics:

Addition and Subtraction, AP (Stage 8)

Required Resource Materials:
Practice exercises with answers (PDF or Word)
Activity:

### Prior knowledge:

Use a range of number strategies for solving addition and subtraction problems with fractions.

### Background:

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.
