Lesson 7 - Angles
Lesson 6 - Symmetry
Lesson 6 - Symmetry
Learning Intention - To describe and identify a line of symmetry.
The simplest symmetry is Reflection Symmetry (sometimes called Line Symmetry or Mirror Symmetry). It is easy to see, because one half is the reflection of the other half.
The first photo is a dog called "Flame"
Her face made perfectly symmetrical with a bit of photo magic.
The white line down the centre is the Line of Symmetry
The second photo is of a lake.
The reflection in this lake also has symmetry, but in this case: the Line of Symmetry runs left-to-right it is not perfect symmetry, as the image is changed a little by the lake surface.
The Line of Symmetry can be in any direction (not just up-down or left-right). To learn more, go to Reflection Symmetry.
Let's get exploring...
Lesson 5 - Quirky Quadrilaterals
Lesson 5 - Quirky Quadrilaterals
Learning Intention- To identify and discuss different types of quadrilaterals
Success criteria
To name different quadrilaterals.
To describe the properties of different types of quadrilaterals.
To work out the value of a missing angle inside a quadrilateral.
To explain mathematical vocabulary such as parallel & perpendicular
Quadrilateral just means "four sides"
(quad means four, lateral means side).
A Quadrilateral has four-sides, it is 2-dimensional (a flat shape), closed (the lines join up), and has straight sides.
Task
Smrf the Google slide below and put it in your Math folder. Work through the interactive slide individually.
Class discussion - talk to a buddy and share your learning about Quadrilaterals.
Lesson 4 - Tricky Triangles
Lesson 4 - Tricky Triangles
Learning Intention- exploring the different types of Triangles.
Success criteria
To name different equilateral, isosceles, scalene and right-angled triangles.
To describe the properties of different types of triangle.
To work out the value of a missing angle inside a triangle
A triangle has three sides and three angles. The three angles always add to 180°
There are three special names given to triangles that tell how many sides (or angles) are equal.
Equilateral: "equal"-lateral (lateral means side) so they have all equal sides
Isosceles: means "equal legs", and we have two legs, right? Also iSOSceles has two equal "Sides" joined by an "Odd" side.
Scalene: means "uneven" or "odd", so no equal sides.
Task
Smrf the Google slide below and put it in your Math folder. Work through the interactive slide individually.
Class discussion - talk to a buddy and share your learning about Triangles.

Lesson 3 - Geometry Fun!
Lesson 3 - Geometry Fun!
Let's get creative and see how many 2D and 3D shapes you can make.
You must ...
Build the shape using the materials provided
Name the shape, edges, vertices and faces to a buddy
Ask Mrs Bava to take a photo
Dismantle and recreate a new shape and repeat the process again
How many shapes can you make and name?
Lesson 2 - Nutting out Nets!
Lesson 2 - Nutting out Nets!
What is a Net?
A net is a two-dimensional figure that can be folded into a three-dimensional object.
Learning Intention
to draw nets for three-dimensional objects.
You will need;
Regular polygon shapes
Square grid paper
Glue, tape, scissors and a ruler
Let's have a go at making some 3D shapes using a NET template or you can level up by designing your own NET.
