Math Manipulatives

Mathartfun.com offers the full line of Tessellations math manipulatives. Being able to handle physical objects engages students on another level to reinforce learning.

Pattern Numbers
$29.95
This set teaches about the properties of numbers and uses colored tiles to illustrate patterns formed by numbers. Colors indicate which numbers are squares, primes, even numbers that aren't squares, and odd numbers that are composite (not prime). The individual tiles contain information about the number on the tile, including its factors and whether it is a factorial, triangular, Fibonacci, or Catalan number. The tiles are shaped to allow vertical alignment of rows or staggered rows for optimal display of various configurations: counting by different numbers, the multiplication table, Pascal's triangle, triangular numbers, Fibonacci numbers, and more. Contains 186 magnetic foam tiles, color instructions, and eight reproducible worksheets. Grades K-12.

Hands-on Trigonometry Proofs
$24.95
This set contains four separate "proofs" of trigonometry relations, with examples of a Pythagorean identity, a sum formula, a double-angle formula, and two sum-to-product formulas. Demonstration of each relation is accomplished by physically rearranging the pieces to establish equalities of areas or lengths. These are not rigorous mathematical proofs, but rather visual common-sense proofs. As such, they help make these abstract relationships real and believable. By actually handling the pieces, students engage their minds to a greater degree than they would by merely looking at the proofs on paper. The color instructions describe how each proof is demonstrated, and four reproducible worksheets reinforce the material. Contains 20 magnetic foam pieces. Grades 7-12.

Conic Sections
$24.95
This set contains four cones cut four different ways to reveal the different conic sections - circle, ellipse, parabola, and hyperbola. Four reproducible worksheets cover various properties of the conic sections, including their descriptions using Cartesian and polar coordinates, their foci, and their eccentricity. Cones measure 2-3/4" across the base and 4" in height. Grades 7-12.

VisuAlgebra Blocks
$29.95
This set contains foam blocks that can be used to visually demonstrate four basic algebra relations. The set uses area and volume to represent terms that are the product of two and three quantities, respectively. The edge lengths of the blocks are labeled in terms of a and b to help students relate the areas and volumes to terms in the above relations. Color instructions describe the use of the blocks to demonstrate these relations. Four reproducible worksheets guide students in the use of the blocks, including measuring and calculating areas and volumes to provide concrete demonstrations of these relations. Contains 12 blocks made from soft, durable, and nontoxic foam. Blocks measure 1" - 3" on a side. Grades 7-12.
