Lines - Gradient – Worksheet A In this activity students use lines with gradients to stun aliens. The worksheets can be completed individually or competitively with students taking turns and recording the stuns they have achieved. Worksheets increase in difficulty and are in a variety of sizes.

Printing To print handouts from slides - Select the slide from the left. Then click: File > Print > ‘Print Current Slide’ To print multiple slides - Click on a section title to highlight all those slides, or press ‘Ctrl’ at the same time as selecting slides to highlight more than one. Then click: File > Print > ‘Print Selection’ To print double-sided handouts - Highlight both slides before using ‘Print Selection’. Choose ‘Print on Both Sides’ and ‘Flip on Short Edge’.
