Links verified on 10/24/11

1. Angles - Students practice their knowledge of acute, obtuse and alternate angles.
2. Area Explorer - Students are shown shapes on a grid after setting the perimeter and asked to calculate areas of the shapes.
3. Baseball Geometry - Select the baseball game to play: identify, measure or label angles, triangles, polygons or rectangles; find the area of triangles, rectangles or circles; use the Pythagoran Theorem to find the length of the hypotenuse and find the circumference of a circle.

4. Calculate the Perimeter of the Rectangle - From FunBrain. A rectangle with the dimensions labeled is shown and you must calculate the area or perimeter of the rectangle. For each problem you get correct, you will receive a piece of an archeological puzzle.
5. General Coordinates Game - Students investigate the Cartesian coordinate system through identifying the coordinates of points, or requesting that a particular point be plotted.
6. Identify Geometric Shapes - Match the shape with the correct name to uncover a picture.
7. Maze Game - Students use their knowledge of points on a graph to move a robot to the target, while avoiding mines.
8. Patterns for Solid Figures - Print off the recording sheet and complete to make a cube figure.
9. Perimeter Explorer - Students are shown shapes on a grid after setting the area and asked to calculate perimeters of the shapes.
10. Perimeter of a Rectangle - Calculate the perimeter of a rectangle with given dimensions - instruction and review, practice, and a quiz.
11. Perimeter of a Square - Calculate the perimeter of a square with given dimensions - instruction and review, practice, and a quiz.
12. Reflective Symmetry - Sort shapes according to their properties.
13. Shape Explorer - Students are shown shapes on a grid and asked to calculate areas and perimeters of the shapes.
14. Simple Coordinates Game - Students investigate the first quadrant of the Cartesian coordinate system through identifying the coordinates of points, or requesting that a particular point be plotted.
15. Simple Maze Game - Students investigate the first quadrant of the Cartesian coordinate system by directing a robot through a mine field laid out on the plane.
16. Triangle Explorer - Students learn about areas of triangles and about the Cartesian coordinate system through experimenting with triangles drawn on a grid.
