Memory games• Do not use this as a power point presentation (i.e.

do not go to view show), use it as it is now.

• Click on the slide down the side to select the topic.

• You can drag the blue squares away and put them at the side. If pupils find a pair leave the blue squares at the side. If they don’t then drag the blue squares back to where they were or press ctrl Z twice.

• Please do not save any changes if prompted to as the blue squares will not be in the correct position if somebody else wants to use it.
