Math Content:
Geometry, Measurement

Guide a turtle to a pond using computer commands.

### Controls

The objective of Turtle Pond is to get the turtle to the Pond. There are four moves:

1. Forward
2. Backward
3. Left Rotation
4. Right Rotation

Create a sequence of moves by using the four action buttons. Once a movement is selected, you will be prompted to enter how many units to move, or how many degrees of rotation to turn.

### Toolbar

There are six toolbar features (left to right, up to down):

1. Erase previous recorded move, or a highlighted move.
2. Erase the entire table.
3. Create a new maze.
4. Turning at right angles vs. ability to turn: 15, 30, 45, 60, 75, or 90 degrees.
5. Create obstacles.
6. Show a grid to help count the units.

### Play Bar

• There is also a play bar that will help play the entire sequence of moves (use the slider to adjust the speed, and stop or pause to halt the play).
• You can also use the fast-forward and rewind button to play the moves one by one.

Enter a sequence of commands to help the turtle get to the pond. The turtle will then move along a path according to your instructions.

• How far does your turtle travel to get to the pond?
• Can you find a shorter path to the pond?
• How long is the shortest path to the pond?

Set forward = 5, back = 7, right turn = 30, and left turn = 75. Using only these possible moves, guide the turtle to the pond. Try the same activity using different values for the four moves.
