Co-ordinate Shapes

Aims and objectives
The activity aims to support student knowledge and understanding in the use of co-ordinates to describe position using both 2D and 3D shapes.

Previous knowledge
To immediately interact with the resource students will need to have an understanding of how co-ordinates are described and interpreted in terms of the ‘x’ and ‘y’ axes. For students without this prior knowledge, the ‘Help’ page will need to be accessed first which will explain, in very straight forward and accessible terms, the basic principles of co-ordinates.

In the classroom
This activity is a highly interactive and engaging environment where pupils can develop their understanding of co-ordinates through the creation of 2D and 3D shapes.

The 'free' environment allows pupils to experiment with co-ordinates by making and/or combining their own co-ordinates to generate shapes. The plotted co-ordinates can be joined together with a drawing tool to create shapes or objects. A print button allows pupils to make hard copies of their work for assessment purposes.

The 'computer generated questions' area consists of 20 questions which prompt students to plot the co-ordinates for a number of 2D shapes, progressing through problem solving activities ending with some very complex 3D tasks. As with the 'free' area, results can be printed for assessment, recording or display purposes.

As a teacher resource, the ‘free’ area can be used to set problem solving tasks, for example, asking the students to create an isosceles triangle with a base of 4 units and the apex at co-ordinate (2,4). Used in conjunction with an interactive whiteboard or in a computer suite this resource can prove to be an invaluable tool in teaching the principals of co-ordinates.

 Support materials description: Resources type: As an extension to this activity, an accompanying activity called ‘Co-ordinate Game’ is also available. The first 5x5_grid.pdf contains a large numbered 5 x 5 grid which can be copied onto a transparency for use with an OHP or printed and laminated to create wipe-clean reusable resource. The second 5x5_blank_grid.pdf contains a blank grid for use as above and the third blank_grids.pdf contains a set of smaller grids which can be used as handouts. 5x5_grid.pdf 5x5_blank_grid.pdf blank_grids.pdf
