Tangram

• Grades K–2
• Math

Tangram: turn and slide seven simple pieces until they fill the shape — a cat, a boat, a rocket. It builds the spatial sense kids use in geometry, with a few drops so flinging pieces doesn't pay.

Free trial: 3 days with the first 25 levels of every game. No card needed.

What it teaches

• Put shapes together to make a bigger picture
• Turn and flip shapes to make them fit
• Recognize shapes in any size or position

Standards

Common Core (Math / ELA)

• CCSS.Math.Content.K.G.B.6 Compose simple shapes to form larger shapes.
• CCSS.Math.Content.1.G.A.2 Compose two-dimensional shapes (rectangles, squares, trapezoids, triangles, half-circles, and quarter-circles) … to create a composite shape, and compose new shapes from the composite shape.
• CCSS.Math.Content.K.G.A.2 Correctly name shapes regardless of their orientations or overall size.

TEKS (Texas)

• TEKS 1.6F Compose two-dimensional shapes by joining two, three, or four figures to produce a target shape in more than one way if possible.
• TEKS 2.8D Compose two-dimensional shapes and three-dimensional solids with given properties or attributes.
• TEKS 2.8E Decompose two-dimensional shapes … and identify the resulting geometric parts.

B.E.S.T. (Florida math & ELA)

• MA.K.GR.1.5 Combine two-dimensional figures to form a given composite figure. Figures used to form a composite shape are limited to triangles, rectangles and squares.
