A protractor is an instrument used in measuring or drawing angles.

Use knowledge of shape properties to draw shapes accurately using rulers and protractors

Maths

Use knowledge of shape properties to sketch and identify shapes

3D shapes can be composed from 2D nets

The same 3D shapes can be composed from different 2D nets

When a 2D shape is decomposed and the parts rearranged, the areas remains the same

Any parallelogram can be decomposed and the parts rearranged to form a rectangular parallelogram

Two congruent triangles can be arranged to compose a parallelogram

Shapes with the same areas can have different perimeters and vice versa

Reason about shapes using the relationship between side lengths and area and perimeter

Reason about compound shapes using the relationship between side lengths and area and perimeter

In this unit pupils will use knowledge of shape properties to draw, sketch and identify shapes  In the future unit pupils will explain how to calculate the area of a parallelogram and a triangle and describe the relationship between scale factors and side lengths of two shapesThey will describe positions in all four quadrants drawing and translating simple shapes and reflecting them in the axes

In the prior unit pupils compared the size of angles with a clear visual difference and use the terms acute obtuse and reflex when describing the size of angles or amount of rotation with relation to right angles using a unit called degrees In this unit pupils will use knowledge of shape properties to draw, sketch and identify shapes

In this unit pupils will use knowledge of shape properties to draw, sketch and identify shapes.

Draw, compose and decompose shapes

All angles exactly the same as each other. 

Which of these descriptions could be describing the interior angles of a triangle?

Alex is plotting a triangle. Which angle has he started to mark out?

Which of these descriptions could be describing the interior angles of a quadrilateral?

The acute angle in this image is {{ }}°.

In special circumstances, they can be 3D shapes.

The interior angles can sometimes be right angles. 

Select all of the statements that are true of polygons. 

Match the letter to the correct protractor part.

Match the number of sides to the shape name.

Match the quadrilateral to the correct name.
