About Math Weave
Math Weave is a crossword made of equations. Number tiles sit at the side of a grid that is already laid out with operators and equals signs. Drag the tiles into the empty cells so that every line reads as a true equation, across and down. The lines cross, so a tile that fits one equation must also work in the other.
It is a daily puzzle that exercises arithmetic and planning at the same time. A new grid every morning, free in your browser.
