1. Equations – From Coordinates – Treasure Trail
Individual students (or pairs) can start the trail at any question poster.
Once they have calculated the answer they should then find the poster that has that answer at the top. Students go from one question to the next until they have completed the full circular trail.
Students should record the letters of the
questions they have completed.
(Clear plastic wallets around your classroom
make it quick and easy to display posters.)

2. Printing To print full page posters - Click:
File > Print. Enter ‘4-20’ in ‘Slides:’ or
Click on the section title to highlight all posters.
To print half-size posters -
File > Print. Select ‘Full Page Slides’, then ‘2 Slides’.
