Extractions: TEAMS Distance Learning - MATHEMATICS PROGRAMS TEAMS mathematics programs complement classroom curriculum for first through eighth grades. They model effective teaching strategies and are starting points to a rich and rigorous mathematics program. Students explore, investigate and use problem solving skills as they develop mathematical thinking skills related to algebra, number and geometry concepts. Through the TEAMS Distance Learning Home Page , teachers and students can access resources that extend and support the mathematics program. The algebra series provides students with activities that build a foundation for understanding algebraic concepts. Algebra: Staff Development Teaching Algebraic Concepts (Two 60-minute programs) These staff development programs help teachers understand what algebraic thinking is and the importance of teaching algebraic concepts throughout the grades. Strategies for helping students develop algebraic thinking are modeled. Program design, teacher guides, and online opportunities for students, teachers, and parents are explored. (Six 30-minute programs) This module develops an understanding of how naturally occurring situations can be represented algebraically. Through active investigation, students model, represent, and interpret number relationships. They use algebraic symbols to create and solve problems using addition and subtraction. Equations are introduced as a way to generalize patterns and describe number relationships.

Extractions: Polyominoes and Other Animals Connected subsets of the square lattice tiling of the plane are called polyominoes . These are often classified by their number of squares, so e.g. a tetromino has four squares and a pentomino has five; this nomenclature is by analogy to the word "domino" (a shape formed by two connected squares, but unrelated in etymology to the roots for "two" or "square"). If a polyomino or a higher-dimensional collection of cubes forms a shape topologically equivalent to a ball, it is called an animal . A famous open problem asks whether any animal in three dimensions can be transformed into a single cube by adding and removing cubes, at each step remaining an animal (it is known that removal alone does not always work). Other related figures include polyiamonds (collections of equilateral triangles), polyabolos (collections of half-squares), and polyhexes (collections of regular hexagons). Anna's pentomino page .

4. PENTOMINOES
pentominoes. By Rashmi Bhat Audrey Fletcher. November 20, 1995. pentominoes are said to have been "invented" by Solomon W. Golomb in 1953 at a talk he gave to the Harvard Mathematics Club. geometry that is ingrained in pentomino discovery is an excellent nonthreatening activity with which to provide students. pentominoes
http://www.andrews.edu/~calkins/math/pentos.htm

Extractions: November 20, 1995 Shapes that use five square blocks joined together with at least one common side are called pentominoes. There are twelve shapes in the set of unique pentominoes, named T, U, V, W, X, Y, Z, F, I, L, P, and N respectively. As a mnemonic device, one only has to remember the end of the alphabet (TUVWXYZ) and the word FILiPiNo. In order to make a set of unique pentominoes, there are only two rules which must be followed. First, if one shape can be rotated to look like another, the two shapes are not considered to be different. Second, if one shape can be flipped to look like another, the two shapes are not considered to be different. Since there are twelve distinct pentomino shapes with each covering five squares, their total area is sixty squares. There are several ways to place all twelve different pentominoes on an 8 x 8 board, with four squares always left over. By artistically specifying the positions of the four extra squares, many interesting patterns can be created. Another evident possibility is to require that the four extra squares form a 2 x 2 area (a square tetromino) in a specified position on the board. This placement leads to a remarkable theorem, which can be proved by using only three constructions: Wherever on the checkerboard a square tetromino is placed, the rest of the board can be covered with the twelve pentominoes. Another problem is to determine the least number of pentominoes which will span the checkerboard. In other words, some of the pentominoes are placed on the board in such a way that none of the rest can be added. Although there are several different configurations for solving this puzzle, the minimum number is five pentominoes. Other patterns include forming the configurations of 6 x 10, 5 x 12, 4 x 15, and 3 x 20 rectangles using all twelve pentominoes. The 3 x 20 is the most difficult to derive, and there is only one unique solution, except for the possibility of rotating the shaded central portion by 180 degrees.
