Term 1 Topic 1: Patterns Unit

We are focusing on different patterns and their links with tables and graphs.

Students have a learning at home day on the 28th of August. Students have been given a sheet of paper with patterns, table and graph activities on it to complete on Wednesday.

Term 1, Topic 2. Geometry and basic angle rules

In this unit, we don't only learn what the basic angle rules are, we start to focus on showing our working and algebraic working to use the rules to find a missing fact.

Please remember that showing units in our answer (doesn't have to be in our working) and showing our working is important for showing logical thinking, and our reasoning when we calculated our answers.

Slide shows below have brief notes and some tasks covered by this unit.

Basic Angle Rules

Angles at a point sum 360 degrees (because of a circle)
Angles on a straight line sum 180 degrees (because of half a circle)
Vertically opposite angles are equal (because of straight lines)

Angles on Triangles

Angles on triangles

Angles in a triangle sum 180 degrees
Determine Triangle types due to angle sizes
External angle = sum of opposite internal angles

Angles Inside Quadrilaterals

Angles inside quadrilaterals

Quad = 4, so quadrilateral is a 4 sided shape
Angles in a quadrilateral sum 360 degrees

Angles on Parallel Lines

Angles on parallel lines

What parallel lines are, and their symbols
Cointerior angles sum 180 degrees
Alt angles are equal
Corresponding angles are equal

Practice test

The geometry test is coming up. Try your skills out using this practice test. You can try as many times as you like and it will give you your score at the end.

Number Unit

Please find below a workspace filled with resources.

Week 8 we are focusing on Negative numbers, multiples, factors and primes.

Angles with Polygons

Extension: Angles and Polygons

More complicated algebra in solving angle problems
Total internal angle sum = 180(n-2) where n= sides of polygon
Total external angle sum = 360 degrees
The difference between a regular polygon and an irregular polygon

Term 2 Probability Unit

It is already Term 4! Please remember your pens, pencils, erasers and calculators! We are going to start the term with Probability. Please see the workspace below for more details for the unit. There will be mini tests - not to worry, they are actually quizzes with 1-4 questions on it that will be done in the last 5 minutes of a class every now and then. These quizzes are great to see what you understand of each skill we are learning this term.

Term 3 at a glance

Term 3

Welcome to Term 3 - This term we will continue to use the number workspace - relinked below for the first half. We will be focusing on percentages, decimals and fractions skills. Extension will branch into algebra and reverse calculations.

The second half we will work on measurement skills. Extension will branch into algebra and graphs. Please find the measurement workspace linked below the number workspace.
