Irregular Polygon Pattern Blocks

thingiverse

This project should be paired with regular polygon pattern blocks found within the math or general education classroom. Three distinct triangles are included: right isosceles, scalene, and right scalene, along with a quadrilateral, rectangle, right trapezoid, and scalene trapezoid. Two pentagons (one featuring a concave angle) and two hexagons (one with a concave angle) also join the collection of shapes. All shapes stand at 5mm tall, while most have at least one side measuring 25mm (resembling the regular polygon block set). Students will still be able to create and solve various tangrams in this way. Each block type is printed in multiple colors, thus eliminating the possibility of identifying shapes solely by color.
