Extractions: A pentomino is an arrangement of 5 unit squares (or sometimes cubes) that are joined along their edges. Up to isomorphism (rotating and flipping), there are 12 possible shapes, which are illustrated below. Each piece is labelled by the letter that most accurately reflects its shape. V T W X U Z F P I N Y L The problem is to fit the 12 pentomino pieces into various shapes, often rectangles. The rectangle shapes that fit all 60 squares are of sizes 3x20, 4x15, 5x12, and 6x10. Here's a solution to the 6 by 10 puzzle using the letter encoding. NFVVVYYYYI NFFFVLLYZI NNFXVLZZZI PNXXXLZWTI PPUXULWWTI PPUUUWWTTT Much better looking is the same solution using tables and gifs. The algorithm used by COS is a clever backtracking algorithm, as described in the upcoming book "Combinatorial Generation." Here is a page of more solutions to various pentomino puzzles.

Extractions: Geometry Activity 1: Pentominos Learning Objectives related to Curriculum: Plane, spatial awareness: Construction of two dimensional objects using pentominos G-16, G-25 Number of Students: 1 or 2 Resources/Materials: Pentomino Grid Pentomino Figure Patterns Pentominos - make your own from the patterns provided or purchase 3D pentominos. Source Acknowledgment: Adapted from Cornelius M. and Parr, M. What's Your Game? Activity Description: Players alternately place a chosen pentomino on the grid (one dimension only). Play continues until one player is unable to make a move. Alternate Ideas: a) place pieces on the board to build desired shapes b) design three dimensional shapes with pentomino pieces (if 3D pentominos are available) Have students build the figures shown on the pages provided. HINTS: a) The first figure is actual size - place pieces directly on the page. b) To build the figures on the pages with grids, use the shapes as indicated on the top of each section. CELS: Numeracy, Communication Social Skills ( working together to build shapes) Critical and Creative Thinking (decision making) Adaptation/Variation/Extension: -to make it easier, shapes using fewer pieces could be designed
