LEARNING OBJECTIVE: You will discover how to substitute values into an equation and find the answer using the rules of BODMAS
SUCCESS CRITERIA: You will be able to find the answer to an algebraic expression given the val;ue of all the variables in that expression
STARTER: BODMAS Song
LESSON: Continue using this lesson to develop Algebra and Substitution skills
Use section 21 from this text book for more practise
PLENARY: Checking answers, feedback from students
LEARNING OBJECTIVE: To practise working out the value of an algebraic expression by substituting the letter(s) for numbers
SUCCESS CRITERIA: You will be able to work out the value of an expression given the values for the letters
STARTER: In each of the following expressions use these values
a = 3, b = 5, c = 8, d = 2.5, e = -3
LEARNING
OBJECTIVE: To discover how to use letters in place of numbers
SUCCESS
CRITERIA: You will know what the following maths words mean – Variable, Term, Expression and can work out the value of an expression of told what value the letter(s) are
STARTER: Copy the following notes into your Exercise Book
Variable – the letter in a term or expression whose value can vary
Term – is an algebraic quantity which contains only a letter(or combination of letters) and may contain a number
eg 3n means 3 x n,
n/2 means n divided by 2,
n2 means n x n or n squared
Expression - a combination of letters(variables) and signs, often with numbers
Eg 8 – n means subtract n from 8
n – 3 means subtract 3 from n
2n + 7 means n multiplied by 2 and then add 7 on
LESSON: Work through This MyMthas Lesson, don't use last screen
Work through Q2 onwards on page 73 of pupil book 2
PLENARY: checking answers, Use last screen of MyMthas Lesson around the room

LESSON Work through This lesson screens 3 to 7 (repeating screen 7 a few times)
Students work through Ex 5C page 59 of Pupil book 2 – Only attempt questions 1, 2, 5, 7 & 8
PLENARY: Checking answers, Confidence feedback from students. Use this interactive bar chart tool around the class
LEARNING OBJECTIVE: To discover how to work out the median and range of a set of data items
SUCCESS CRITERIA: Giving a set of data you will be able to work out the median value and the range of the data
STARTER: Find the mode and mean of the following two data sets
4 | 6 | 3 | 4 | 3 | 4 | 6 | 7 | 8 | 4 | 6 | 4 | 7 | 9 | |||||||
Answer 4 + 6 + 3 + 4 + 3 + 4+ 6 + 7 + 8 + 4 + 6+ 4 + 7 + 9 = 75, 75 / 15 = 5
Mode = 4
1.2 | 2.3 | 2.6 | 2.3 | 2.1 | 2.5 | 2.3 |
Answer: 1.2+2.3+2.6+2.3+2.1+2.5+2.3 = 15.3, 15.3 / 7 = 2.1857142
Mode = 2.3
LESSON: Work through This Mymaths lesson – encourage lots of participation. Use questions screen repeatedly if needed
If Time have a go at Ex 5B on page 57 of Year 7 Pupil book 2 From Question 3 onwards.
EXTENSION: Work through Ex 5B from Question 7 Onwards
PLENARIES: Checking answers around room, stopping class and looking at any issues, feedback from Students
