Draw lines along cell edges so as to divide the grid up into regions. Every region should have two-way rotational symmetry, and should contain exactly one dot which is in its center.
Click on a grid edge to add or remove a line. Right-click on a dot and drag the mouse to place an arrow in a grid square pointing to that dot, to indicate that you think that square must belong in the same region as that dot. Right-drag an existing arrow to move it, or drop it off the edge of the grid to remove it.
We hope that the free math worksheets have been helpful. We encourage parents and teachers to adjust the worksheets according to the needs of the child. For more difficult questions, the child may be encouraged to work out the problem on a piece of paper before entering the solution. We hope that the kids will also love the fun stuff and puzzles.
