Co-ordinates
In lessons one and two, explore right-angled triangles and Pythagoras' theorem using simplified engineering drawings, and use co-ordinates to create a simple map of the proposed Thames Tideway Tunnel route.

Maths KS3 Lesson 2: Co-ordinates
Screen 2.1: Engineers can use co-ordinates to locate site positions on a map. To do this, they need to use a grid. Click the next arrow to see how we find the point's coordinates.
Screen 2.2: Engineers can use co-ordinates to locate site positions on a map. To do this, they need to use a grid. Click the next arrow again to see how we find the point's coordinates.
Screen 2.3: Engineers can use co-ordinates to locate site positions on a map. To do this, they need to use a grid. Click the next arrow again to see how we find the point's coordinates.
Screen 2.4: Engineers can use co-ordinates to locate site positions on a map. To do this, they need to use a grid.
Screen 2.5: Watch carefully to see how a 1km x 1km square of Great Britain can be identified using a four figure grid reference.
Screen 2.6: Watch carefully to see how a 1km x 1km square of Great Britain can be identified using a four figure grid reference.
Screen 2.7: Watch carefully to see how a 1km x 1km square of Great Britain can be identified using a four figure grid reference.
Screen 2.8: Watch carefully to see how a 1km x 1km square of Great Britain can be identified using a four figure grid reference.
Screen 2.9: Using what you have learnt from the previous two screens how accurate are these coordinates?
2.9b: The correct answer
Screen 2.10: Pythagoras' Theorem can help Engineers work out distances too.
2.10b: Correct answer
Screen 2.11: Pythagoras' Theorem can help Engineers work out distances too.
2.11b: Correct answer
Screen 3.1: When you’ve finished plotting each location on your worksheet, click next to confirm which construction site goes where.
Screen 3.2: When you’ve finished plotting each location on your worksheet, click next to confirm which construction site goes where.
