KindergartenK.G.3
Identify shapes as two-dimensional (lying in a plane, “flat”) or three-dimensional (“solid”).
Toyineer begins with flat printed parts and transforms them into three-dimensional structures, giving educators a direct physical example of the distinction between 2-D and 3-D form.
KindergartenK.G.4
Analyze and compare two- and three-dimensional shapes, in different sizes and orientations, using informal language to describe their similarities, differences, parts (e.g., number of sides and vertices/“corners”) and other attributes (e.g., having sides of equal length).
Learners hold a flat printed part and the three-dimensional form it becomes after folding. Educators can ask them to compare the two, describing similarities and differences and counting sides, edges and corners.
Grade 11.G.2
Compose two-dimensional shapes (rectangles, squares, trapezoids, triangles, half-circles, and quarter-circles) or three-dimensional shapes (cubes, right rectangular prisms, right circular cones, and right circular cylinders) to create a composite shape, and compose new shapes from the composite shape.
Learners join separately folded components, such as box-like housings and sleeves, into larger assemblies, and then combine those assemblies into one composite mechanical object.
