Have the children all sitting round a large sheet (or large sheet of paper) that you have drawn and numbered a large grid on.

Recap what co-ordinates are, linking to directions and compass points with related vocabulary, turns and related vocabulary and degrees of turn. Then demonstrate how to send the Roamer to a certain co-ordinate, talking about the directions and turns made in degrees.

Allow children to have a go using co-ordinates that you give them.

To extend, use vocabulary related to compass points. You can also make this into a game, where children are split into two teams and given two different colour counters. Use two large sponge dice.

Each team takes turns to programme the Roamer to reach a co-ordinate that is decided by throwing the two dice (reinforcing turns and angles of turn in degrees). They then mark the co-oridinate reached.

The winning team is the first to get four crosses in their colour in a row, horizontally, vertically or diagonally (a bit like Connect 4).

A fun way to get ICT skills into maths teaching and learning!
