Time

Choose 5 times. Record.

*Can you order the times? (earliest to latest)

*Can you record the times in different way

1. Record your times in words?

2. Record your times on an analog clock

3. Record your times on a digital clock

4. Record your times in 24hr time

Needs to be completed by friday lesson, plus

worksheet and glue into book.

Worksheet Examples

Remember read example page. Complete 2 worksheets. You may use calculator for conversions.

Example

Page 1

Question 1

To convert 1 min to seconds

There are 60 seconds in 1 min

1 x 60 = 60 seconds

To convert 4 min to seconds would be

4 x 60 = 240 seconds

Question 2

This one is a two step conversion

convert 28 days to fortnight

28 / 7/2 = 2 fortnights

Another way

You know 7 days in a week

28 days convert to weeks

(28/7= 4 weeks)

You know 2 weeks to a fortnight

(4/2 = 2 fortnight)

Therefore 28 days equals 2 fortnights.

Question 3

Simple conversion using decimal or fractio

1.5 hour to minutes = 1.5 X 60 = 90 minutes

Question 4

Two step conversion using fraction or decimal

Convert 15 months to weeks

15 months = 1 3/12 years
                   = 1 1/4 years
Convert to weeks
1 1/4 years= 52 + ( 1/4 of 52)
                  = 52 + 13
                  = 65 weeks

Question 5 & 6 challenges

3. Check with a protractor to check your angles and ruler to measure your sides.

4. Inside each one, name its properties (that is, what makes each triangle a scalene, isosceles etc)

5. Explain how each triangle named above can be either an acute angled triangle, a right angled triangle or an obtuse angled triangle. (e.g. an equilateral triangle can be also be a _______

Circles

Thursday 31/8

WALT: Students learn to identify and names parts of circles to include: centre, radius, diameter, circumference, sector, semicircle and quadrant.

Go through the sections using the website https://www.det.nsw.edu.au/eppcontent/glossary/app/resource/factsheet/4025.pdf

As class

Students draw a circle in their maths book.
The centre of a circle is a fixed point in the middle of the circle. The distance from the centre of a circle to any point on the circumference of the circle is always the same. Label the centre point M.
The circumference of a circle is the edge or perimeter of the circle.Trace the circumference with a red pen.
The radius of a circle is a straight line that has one endpoint on the centre of the circle and the other endpoint on the circumference of the circle. Draw the radius with a blue pen.
The diameter of a circle is a straight line that passes through the centre of the circle and has both endpoints on the circumference of the circle.The diameter of a circle is twice as long as the radius of the circle. Draw the diameter with a green pen.
Semicircle is half a circle. Shade in a semicircle
Sector is the portion of a disk enclosed by two radii and an arc. Draw a sector.
Quadrant is A quarter of a circle (made by two radius's at right angles and the connecting arc). Shade in a quadrant using a different colour.
The chord of a circle is a straight line that has both endpoints on the circumference of the circle. Draw a chord with a black pen

Students have time to revise 2d shape and ask the teacher questions.

Area

Area of Rectangle/ Square

How can we calculate the area?

By counting the squares

By skip counting to match the numbers of rows or columns

By using the formula area= length x width

This example Area= 3 x 5 = 15 squares

Practise these ones in your book

Area of Parallelogram

Area of parallelogram is same as rectangle and is the length multiplied by the width.

Area of Compound Shape

Break the shape into smaller shapes.

Try these ones

Area of Triangle

A triangle is half a rectangle . To find the area of a triangle you need to find the area of the rectangle then divide by 2.

Area Triangle = base length x height x 1/2
