Three workspaces
Use pattern blocks, tangram pieces or tessellation mode depending on the lesson.
Free maths tool
Pattern blocks tool
A free classroom workspace for building with pattern blocks, tangram pieces and tessellation grids.
Grid choices
Switch between square, triangle and isometric grids for different tiling and shape tasks.
Tile actions
Select a tile, then rotate, flip, duplicate, delete or clear the board.
Task mats
Use cover hexagon, tangram square, tiling strip, symmetry line and quick tessellation prompts.
What the tool does
The pattern blocks tool gives teachers and students an open digital workspace for tiling, shape composition and transformations.
- build with pattern block and tangram tile palettes
- switch between square, triangle and isometric grids
- drag pieces around the workspace
- rotate, flip, duplicate and delete selected pieces
- use task mats and quick tessellation presets for classroom prompts
How teachers use it
Open it on a classroom display when students need to compose shapes, compare area parts or reason about tiling patterns.
- cover the hexagon with smaller pattern blocks and discuss equivalent areas
- use the tangram square task to talk about composing and decomposing shapes
- switch on a symmetry line and ask students to build a matching design
- load a quick tessellation and ask students to describe the repeating unit
Why it is useful
Pattern blocks make geometric structure visible. A shared digital workspace lets the whole class discuss the same tiles, grid and transformations.
- supports shape composition, fractions and area language
- makes rotation, reflection and tiling visible
- works as a model before independent geometry practice
Frequently Asked Questions
Is the pattern blocks tool free?
Yes. Teachers, students and families can open the pattern blocks tool in a browser for free.
What tiles are included?
The tool includes pattern block shapes such as hexagons, trapezoids, rhombi, triangles and squares, plus tangram pieces.
Can students rotate and flip pieces?
Yes. Students can select pieces, rotate them, flip them, duplicate them, delete them or clear the board.
Does it include tessellation prompts?
Yes. The tool includes quick tessellation presets, grids and task mats such as tiling strip and symmetry line.
