# 3-d shapes

## Activity 1

### 1.  Objectives

1.1  Names of 3-D shapes.

1.2  Properties of 3-D shapes.

1.3  Identify and examine 3-D shapes and explore relationships.

1.4  Draw the nets of simple 3-D shapes and construct the shapes.

### 2.  Recall

2.1  Using paper, scissors, glue, colouring pencils and paper/cardboard create the following 3-d nets:

1.  A sphere

2.  A triangular based pyramid

3.  A rectangular based pyramid.

4.  A square based pyramid.

5.  A cube

6.  A cuboid

7.  A hexagonal prism

8.  An octahedron

2.2  Label the shapes.

2.3  Create a table listing the names of the shapes.

2.4  Add the following categories to the table and fill in the correct information:

Faces

Edges

Vertices

How many angles

The value of the angles

2.5  Sketch the shapes that you created from three elevations, front, top and side.

2.6  Measure the length of each side of the shapes.

2.6  Record the length of each side of the shapes.

2.7  Calculate the area of each shape.

2.8  List the area of each shape and record the algorithm for obtaining the area under each shape.

### 3.  Activity

Create a presentation/poster including the following:

3.1  Sketches of the shapes you created.

3.2  Images of the shapes you created.

3.2  The names and properties of the shapes you created.

3.3  The algorithms for calculating the area of each shape.

### 4.  Assessment

Your artefacts will be assessed on the following criteria:  (100 marks)

Poster/presentation

4.1  Accuracy of each shape.  (18%)

4.2  The names of each shape. (18%)

4.3  The correct properties of each shape, including:

Faces  (6%)

Edges (6%)

Vertices (6%)

4.4  The clarity and design of the poster/presentation.  (10%)

Models of 3-d shapes

4.5  Accuracy of each shape.  (18%)

4.6  The form, stability and materials used to design of each shape.  (18%)

## Activity 2

### 1.  Objective

1.1  Names of 3-D shapes.

1.2  Properties of 3-D shapes.

1.3  Identify and examine 3-D shapes and explore relationships.

1.4  Draw the nets of simple 3-D shapes and construct the shapes.

### 2.  Recall

2.1  Measure the length and area of the shapes you created in centimetres.

2.2  Convert the length and area of the shapes you created from centimetres into minecraft blocks.

2.3  Sketch each shape in Minecraft blocks from three different elevations, front, top and side.

2.4  In Minecraft (using turtles, where possible), design, develop and debug code to create the following shapes.

2.5  A sphere

2.6  A triangular based pyramid

2.7  A rectangular based pyramid.

2.8  A square based pyramid.

2.9  A cube

2.10  A cuboid

2.11  A hexagonal prism

2.12  An octahedron

2.13   Record examples of your code at the design stage, the development stage and the debugging stage.

2.14  Take a screen capture of the shapes and save them.

2.15  Create a table listing the names of the shapes you created.

2.16  Add the following categories to the table:

Faces

Edges

Vertices

Area

Formula

Codes

2.17  Outline the difference in codes used to create each shape.

2.18  Outline the similarities in code used to create each shape.

### 3.  Activity

Create a poster/presentation that includes the following:

3.1  Examples of the shapes you created

3.2  The names of each shape.

3.3  The faces, edges and vertices for each shape.

3.4  The area of each shape.

3.5  The code used to create each shape.
