# Fractions: Decimals

### Fractions and decimals: how are they related.

We know:

0.25 = 1/4

0.5 = 1/2

0.75 = 3/4

But what do we need to do to read this and understand this…

1 divided by 4 =====

1 divided by 2 =====

3 divided by 4 =====

# Area and Perimeter

Here is some of the maths we have been focusing on:

On Area and Perimeter- The formulae for Area is:

A= Width X Length

The formulae for Perimeter is:

P= A + B + C + D

# Symmetry

Symmetry

Learning Intention:

We are learning to identify line and rotational symmetry

Success Criteria:

– I am able to visualise a polygon or object being rotated (rotational symmetry)

– I am able to visualise a polygon or object being divided into equal parts (line symmetry)

– I can find lines of symmetry and draw them

– I can rotate polygons

– I can demonstrate line and rotational symmetry

BIG QUESTION NO1:

What is a polygon?

polygon: a plane figure with at least three straight sides and angles, and typically five or more.

BIG QUESTION NO2:

What is symmetry? We want to look at 2 types of symmetry.

Line symmetry:

Rotational symmetry:

Activity:

Draw 5 Shapes that have line symmetry and 5 shapes that have rotational symmetry.

# Data Collection

How much data is round!

We are looking our fitness and combining this with our mathematics focus of data. We have been doing 1 minute exercises and recording the data.
