Working With Pattern Blocks

Above are traditional wooden versions of Pattern Blocks. There are educational, toy companies that now manufacture
Pattern Blocks in plastic. If you can not afford either of these, you may cut out your own templates from paper.
        Pattern Blocks are one of the mathematical manipulatives developed in the 1960s by an Education Development Center as part of their Elementary Science Study project. They allow children to see how shapes can be decomposed into other shapes, and introduce children to ideas of tilings.

The Pattern Blocks includes multiple copies of six shapes in the following colors:
  • Equilateral triangles are green. In geometry, an equilateral triangle is a triangle in which all three sides are equal. In the familiar Euclidean geometry, equilateral triangles are also equiangular; that is, all three internal angles are also congruent to each other and are each 60°. They are regular polygons, and can therefore also be referred to as regular triangles.
  • Rhombus tiles that can be matched with two of the green triangles are blue. In Euclidean geometry, a rhombus(◊) (plural rhombi or rhombuses) is a simple (non-self-intersecting) quadrilateral whose four sides all have the same length. Another name is equilateral quadrilateral, since equilateral means that all of its sides are equal in length. The rhombus is often called a diamond, after the diamonds suit in playing cards which resembles the projection of an octahedral diamond, or a lozenge, though the former sometimes refers specifically to a rhombus with a 60° angle (see Polyiamond), and the latter sometimes refers specifically to a rhombus with a 45° angle. Every rhombus is a parallelogram and a kite. A rhombus with right angles is a square.
  • Trapezoid that can be matched with three of the green triangles are red. In Euclidean geometry, a convex quadrilateral with at least one pair of parallel sides is referred to as a trapezoid (/ˈtræpəzɔɪd/) in American and Canadian English but as a trapezium (/trəˈpziəm/) in English outside North America. The parallel sides are called the bases of the trapezoid and the other two sides are called the legs or the lateral sides (if they are not parallel; otherwise there are two pairs of bases).
  • Hexagon that can be matched with six of the green triangles are yellow. In geometry, a hexagon (from Greek ἕξ hex, "six" and γωνία, gonía, "corner, angle") is a six sided polygon or 6-gon. The total of the internal angles of any hexagon is 720°
  • Squares with the same side-length as the green triangle are orange. In geometry, a square is a regular quadrilateral, which means that it has four equal sides and four equal angles (90-degree angles, or (100-gradian angles or right angles). It can also be defined as a rectangle in which two adjacent sides have equal length.
  • Narrow rhombus with a 30° angle and the same side-length as the green triangle are white or beige.
       My patterns come with both questions and activities so that classroom teachers or homeschooling parents may use either a lap top or a desk-top computer center for creating interactive learning experiences for students reading this blog in specific:
  1. Set up a learning center using a computer, laptop or tablet with access to pages only. The content must not be transferred to an alternative web location.
  2. Provide a couple of sets of Pattern Blocks for each work space and paper with writing tools as well. 
  3. Pick and choose the questions or actions that you want your students to answer or manipulate according to their age/abilities.
  4. To enlarge the images, simple click on the image and you will be able to see a larger version on a dark background.
       If your students can not yet read, simply have them configure the same design in front of themselves with Pattern Blocks on a table or desk. Students can do this activity by themselves or in a group at a large table. This activity helps develop Pre-Math Skills: problem solving, patterning, estimation, sense of space, representation (symbolism) and number sense.
