Weds 25th – Expressions and Equations, solving simple linear equations

LEARNING OBJECTIVE Understand the difference between an equation and an expression and discover how to solve an equation

SUCCESS CRITERIA: You will be able to explain what we mean by an expression, what we mean by an equation and know how to solve an equation

ENGAGEMENT ACTIVITY:

Copy These Notes into your Exercise Book, then answer the following questions

1. An EXPRESSION is a collection of numbers and letters joined by mathematical processes
   

   Eg. 3x + 5y, 2a + 4b + 4z, 5(2x-3t) + 7(4a + 7g)..
   

2. An equation MUST contain an equals sign may contain numbers and letters and mathematical processes
   

   Eg 3x = 6, 5x + 2y = 34, 32t = 24 – 5t...
   

For each of these questions state whether it is an equation or an expression, using the above notes.

1. 3t + 5d
   
2. 23x +5 = 12
   
3. 34x + 65t – 7
   
4. 3a + 4b = 5d – 6c
   
5. 4(5a-3) = 32
   
6. a+2b-3c-7t
   

 
 

LESSON: Look at simple equations like 3x = 18, 4m = 12, x+1 =6, m – 3 = 6..... Give students 15 mins max to answer Q1 and q2 on page 79 of Year 7 Book 2

Look at how to solve simple linear equations using this lesson
