### Identifying 2D and 3D Shape Study Guide

1. 1. Parent Guide Identifying and describe the properties of 2D and 3D shapes
2. 2. Chapter 1 The Expectations 2 Contents Contents Chapter 2 Common Problems Chapter 3 Asking questions Chapter 4 Creative Maths Chapter 5 Motivating your child Chapter 6 Resources 3 10 11 13 15 17
3. 3. The Expectations End of Year Expectations 3 The Expectations The expectations are that your child should be able to identify and describe the following shapes: 2D Shapes are flat shapes Circle Square Rectangle Triangle Pentagon Hexagon Octagon 3D Shapes are solid shapes Cylinder Cone Sphere Cube Cuboid Pyramid
4. 4. The Expectations 4 The Expectations Parts of a 2D shape corner They will need to be able to describe the shapes they see, in terms of how many corners and sides it has and if the sides are straight or curved. Straight side
5. 5. The Expectations 5 The Expectations Square It has 4 straight sides Each straight side is the same length It has 4 corners Rectangle It has 4 straight sides It has 2 long sides and 2 short sides It has 4 corners Triangle It has three sides and three corners Pentagon It has 5 straight sides It has 5 corners It can come in a variety of forms Hexagon It has 6 straight sides It has 6 corners It can come in a variety of forms Circle It has one curved side Octagon It has 8 straight sides and 8 corners It can come in a variety of forms Star It has points coming out of the centre Describing 2D Shapes
6. 6. The Expectations 6 The Expectations Variety of forms Remember, 2D shapes are identified by how many sides they have. The way they look can vary. All triangles All hexagons All octagons
7. 7. The Expectations 7 The Expectations Parts of a 3D shape corner edge face They will need to be able to describe 3D shapes in terms of how many; faces, edges and corners it has.
8. 8. The Expectations 8 The Expectations Cube It has 6 square faces all the same size. It also has 8 corners and 12 edges. Square based pyramid It has 1 square face and 4 triangular faces Cylinder It has 3 faces (2 flat and 1 curved), 2 edges and no corners. Cuboid It has 6 rectangular faces. Sphere It has only one curved face Cone It has a circle as its base, a curved face and a point. Describing 3D Shapes
9. 9. The Expectations 9 The Expectations Understanding the Vocabulary Vocabulary Definition Flat A flat object has a level surface with no ups or downs. Curved A line that is not straight or an object that is not flat. Side A line in a 2D shape is called a side. Straight A line or edge which has no curves is straight. Corner Two or more edges or sides meet at a corner. Face A face is a flat surface on a 3D shape. A pyramid has 5 faces. Edge An edge is where 2 faces meet in a 3D shape. Solid A solid shape has no space inside it. Point A sharp part of a shape is a point. A pyramid is pointed at the top.
10. 10. Common Problems Common Problems 10 Common Problems As your child works understanding 2D and 3D shapes, they may encounter a few common problems: • Mixing up the names of 2D and 3D shapes. • Not understanding that 2D shapes are flat and 3D shapes are solid. • Seeing a net of a 3D shape in a picture and naming it as a 2D shape. • Not understanding the vocabulary correctly and mixing up corners and edges. • Not fully understanding what the properties of the 3D shapes mean when describing them.
11. 11. Asking questions What is the name of a three sided shape? 11 Asking questions How many corners does a hexagon have? How many sides does a circle have? What is the difference between a circle and a sphere?Explain what a pyramid is Questions enable you and your child to find out what they know and can guide you to identifying their next steps How many squares can you see in this room? How many edges does a cube have? Name another shape with the same amount.Show me a cylinder/cone/cube/cuboid/pyramid
