Mon Oct 3rd – Solving Inequalities

LEARNING OBJECTIVE: To manipulate and solve inequalities

SUCCESS CRITERIA: You will be able to solve inequalities using algebraic manipulation.

STARTER: Hand back Exam Papers, give them 5 mins to talk about them. Look at Q1,2 and 3 together on IWB after giving students 5 minutes around their tables to explain to each other how to do these questions

LESSON: Solving Inequalities

Use these examples to show how to solve Inequalities:

1. x + 15 > 25
   
2. x – 21 < 4
   
3. 2x – 3 > 5
   
4. 3(x +3) < 21
   

Work Through Ex 26A on page 565 of Higher text book, Check answers as you work through questions

If Level C questions too easy for some skip to level B questions (Q4 onwards)

EXTENSION: Page 76 from Unit 2 Higher text Book

PLENARY: Have a go at Q 9(a) on exam paper.
