In this worksheet, students cut out a tangram set, and put the different shapes together to make a set of designs. This can be used with our other tangram resources to create interesting puzzles for students. It is part of a larger unit that teaches students to compare and describe the 2 dimensional shapes that result from combining or splitting common shapes.
Represent and approximate composite shapes and objects in the environment, using combinations of familiar shapes and objects
Compare and describe two dimensional shapes that result from combining and splitting common shapes, with and without the use of digital technologies
Compare and describe two dimensional shapes that result from combining and splitting common shapes, with and without the use of digital technologies
Explain and compare the geometric properties of two-dimensional shapes and three-dimensional objects
Uses appropriate terminology to describe, and symbols to represent, mathematical ideas
Selects and uses appropriate mental or written strategies, or technology, to solve problems
Checks the accuracy of a statement and explains the reasoning used
Manipulates, identifies and sketches two- dimensional shapes, including special quadrilaterals, and describes their features
Compares two-dimensional shapes and describes their features
Performs transformations by combining and splitting two-dimensional shapes
Estimates, measures and compares areas using square centimetres and square metres
Makes and sketches models and nets of three-dimensional objects including prisms and pyramids
Estimates, measures and compares capacities (internal volumes) using litres, millilitres and volumes using cubic centimetres
