Mastering Key Maths Skills: Revision
What do you already know about the main maths skills for year 8?
Learning Objective
At the end of the lesson you will be able to apply and review core maths topics, such as fractions, graphs, proportion, ratio, algebra, symmetry and reflection.
Multiplying Fractions
To multiply fractions, multiply the numerators together and the denominators together.
Question: Multiplying Fractions
What is 3 quarters multiplied by 5 sixths
Dividing Fractions
To divide fractions, multiply by the reciprocal of the second fraction. Do not forget the KFC method (Keep, flip, change)
Question: Dividing Fractions
1) 5 sixths divided by 2 thirds
2) 3 quarters divided by 9 thirds
3) 8 ninths divided by 5 sixths
Graphs and Coordinates
Coordinates are written as (x, y). Plot points by finding the x-value across and y-value up/down on the grid.
Question: Plotting Coordinates
Where would you plot (4, 2) on a graph? Describe the position.
Proportion and Scale
Proportion compares part to whole. Scale changes the size. Eg: A scale of 1:2 means everything is made twice as big.
Ratio Review
A ratio compares two quantities, for example 2:3.
What is Ratio?
Simplifying Ratios
Divide both parts by the same number. Eg: 4:6 simplifies to 2:3.
Algebraic Manipulation
You can change the order or group terms in algebra as long as the equality holds. For example, \( 2x + 3x = 5x \).
Question: Algebra Practice
If x = 2 , what is the value of (3x + 4)
Symmetry and Reflection
A shape is symmetrical if one half is a mirror image of the other.
What is Symmetry?
What is Reflection?
Reflection flips a shape over a line (mirror line).
Revision Activity: Name the Skill
Look at a problem and identify if it is about fractions, graphs, proportion, ratio, algebra or symmetry.
Lesson Summary
You reviewed multiplying/dividing fractions, graphs, proportion, ratio, algebra, and symmetry. Keep practising to master these key skills!
