Watch the shape on the screen. It has moved three squares across to a new spot. Look at it where it started and where it finished.

Tell me in your own words what you saw the shape do.

When a shape slides, it moves to a new place but keeps facing the same way. It does not turn and it does not flip. That is the whole test for a slide: if the shape still faces exactly the same way, it slid.

Each picture below shows a shape before and after a slide. Every corner has moved the same number of squares in the same direction.

A shape can slide in any direction, not only right and down. The third picture below shows a shape that has slid to the left.

The fourth picture below shows a shape that has slid up.

In the last picture the shape has slid two ways at once. See where each corner has ended up.

Now we slide the shape together on the board. Each turn moves the shape on from wherever it is now — a slide just pushes it that many squares in that direction. Take turns:

• 2 squares right
• 3 squares down
• 2 squares left and 1 square up
• 3 squares up

Now we slide shapes to hit a target outline on the grid. Take turns:

• 2 squares right
• 3 squares down
• 3 right and 2 down
• 4 right and 1 up
