Distance-Time Graphs – Variable – Card Match In this activity students work individually or in groups to match questions and answers. ‘Quick Cut’ – Choose the questions/slides you wish to use and delete others. Sets of questions can then be easily guillotined to save time. One-sheet sets of cards are also included for students to cut out themselves.

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’.

Match each Distance-Time Graph with the turning point (vertical speed = 0) and a speed
