# GM2-4: Identify and describe the plane shapes found in objects.

Elaboration on this Achievement Objective

This means students will be able to identify plane (flat) shapes in objects and structures around them and consider why the given shape is suitable for its purpose, for example wheels are circular so they roll freely, floors are usually rectangles because they are easier to build and things fit efficiently, etc. They should consider how three dimensional objects are built from flat shapes through pulling packets apart and constructing solids of their own, for example nets for cubes.

Teaching resources for this Achievement Objective

The purpose of this activity is to engage students in applying their knowledge of fractions in a geometric context.

Level Two

In this unit students investigate the features of solid shapes and learn the names for them. They will be introduced to making nets for 3D shapes.

Explore and describe faces, edges, and corners of 2D and 3D objects. Make, name and describe polygons and other plane shapes.

Level Two

This interactive learning module supports students to think about features of shapes they see in the world around them, and how do describe them.

Use words that tell us about shapes. Identify features of two and three dimensional shapes. Find plane shapes in 3D objects. Explain why shapes are used for particular purposes.

Level Two

In this unit students sort and explore two-dimensional and three-dimensional geometric shapes, identify and describe their distinguishing features and come to appreciate the efficiency of the tessellating hexagon in meeting the needs of honeybees.

Identify distinguishing features of 2D (plane) shapes using the language of sides and corners. Identify distinguishing features of 3D shapes using the language of faces, edges, vertex/vertices. Explore hexagons, recognising that they tessellate. Make hollow prism shapes and describe their features...

This unit provides you with a range of opportunities to assess the entry level of achievement of your students.

Classify whole numbers as even or odd and generalise the nature of sums when even and odd numbers are added. Recognise that sums remain the same if the same amount is added and subtracted to the two addends, e.g. 17 + 19 = 27 + 9. Create and follow instructions to make a model made with shapes...
