What are we learning this half term?Unit 8: Reading Scales

This Unit will introduce you to reading scales and interpreting measurements for a range of quantities and metric units.

Unit 9: Angles and Angle Properties of Straight lines Next you will learn to classify angles including acute, right, obtuse and reflex angles. You will be introduced to finding,

estimating, measuring and drawing angles using a protractor.

Unit 10: Properties of Triangles You will extend your understanding of angle properties by drawing and making angles within the context of triangles.

You will also be introduced to symmetry and classifying triangles.

Unit 11: Properties of Quadrilaterals You will investigate the properties of quadrilaterals including parallel and perpendicular lines and use this to discuss,

classify and draw quadrilaterals.

Unit 12: 2D-Shapes in Rich Contexts This unit will help you connect content from all of the previous units through a variety of investigative tasks on 2D-

Shapes.

Finishing TaskSam is investigating shapes. First she looks at a regular octagon (a shape with eight equal sides).

She discovers that to find the angle a (called an exterior angle) you divide 360 by the numbers of sides. Then to find angle b (called an interior angle) you subtract a from 180.

Help Sam find the angles a and b for a regular octagon

a = ……………

b = …………..

She also works out that the sum of all the interior angles is equal to the the angle b multplied by the numbers of sides. Calculate this too.

Sum of interior angles = …………………………………….

Use Sam’s rules to find the interior angles of other polygons – you might already know them for a triangle and a square.

See how many you can accurately draw using a protractor and a ruler.

For some polygons it’s hard (or even impossible) to work out an exact value for the interior angle – why are some easier than others?
