Pieces that snap
Every piece is made of small triangles, so it snaps to the grid and meets its neighbors exactly. A filled outline can be checked: no gaps, no pieces on top of each other.
For kindergarten to grade 2
Pattern blocks the whole class can build with
Triangles, rhombuses, trapezoids and hexagons that snap to a grid. Lessons give you outlines to fill, to fill another way, to split into equal parts and to mirror.
Free, with no sign-up. Nothing about you or your class is kept.
Try it now. No sign-up needed.
Drag a piece onto the mat, or tap it in the tray. Tap a piece to turn it; drag it off to take it away.
This is the real mat. The full mat and its lessons are free.
Fill it, split it, mirror it
A lesson is a chain of shapes: "Fill the boat", then "Make the hexagon another way", then "Fill it with three equal pieces", then "Build the other half of the fish".
Send it home
Every lesson has its own link. Bookmark it, open it on the board, or send it home and the same shapes come up on a phone or tablet.
