## Foundation Statement strands

The following strands are covered in this activity:

## Description of activity

Students draw a ‘Treasure Island’ map and mark where the treasure is hidden. They create a scale and a compass rose. Students draw a grid and put coordinates on their map. They write a set of directions, using compass points and grid coordinates, to the location of the hidden treasure on their map. Students exchange maps and follow the directions to find the treasure. They then modify their directions if required.

## Suggested materials

Blank paper, grid paper, pencils

## Prior learning

Students have found places on maps using coordinates and have used a map to plan a route. They have drawn and labelled a grid on a map and used a scale to calculate the distance between two points on a map.

## Criteria for assessing learning

Students will be assessed on their ability to:

• draw a map using a scale and a compass rose
• draw a grid and put coordinates on the map
• use compass points and grid coordinates to write directions to a location on the map.
