S-2739T Advanced Geometric Shapes 15 幾何形狀

S-2999T Conic Sections 圓錐曲線;二次曲線
　
Set of 15 shapes. Key parameters such as edge length and angles are labeled on one side of each piece, with the name of the shape and its area printed on the other side. Allows shapes to be used like flash cards to help students learn names of shape and calculate the area of shapes.
　
A great set for hands-on geometry activities. 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 conic sections, including their descriptions using Cartesian and polar coordinates, their foci, and their eccentricity. Cones measure 2-3/4" W x 4" H. Includes eight geometric solids made from soft, durable, and nontoxic foam.
　
　 　

S-2998T VisuAlgebra Blocks

S-2441T Cubed Cubes立方體
Help students visualize and demonstrate four basic algebra relations for better understanding with foam blocks. This 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 the variables a and b to help students relate the areas and volumes. Color instructions describe the use of the blocks to demonstrate these relations. Four calculating areas and volumes provide concrete demonstrations of these relations. Blocks measure 1"-3" on a side. Includes 12 blocks made from soft, durable, and nontoxic foam.
Cubed Cubes is four puzzles in one. This set of nine foam rectangular solids forms three different cubes, one in each of three colors. All nine pieces combine to form a single large cube. Five other brain teasers are included in the instructions. Puzzle exercises spatial reasoning and problem-solving skills. Two reproducible worksheets cover measuring and calculating the volume of rectangular solids and provide an introduction to cubic numbers.

S-3000T The Irrational Puzzle

S-7821T Four-Pan Algebra Balance 代數天秤
　
Four cubes are dissected in four different ways to form a variety of geometric solids. The instructions contain seven brain teasers in which different 3-D shapes are formed with the pieces. This puzzle uses physical shapes and diagonals of squares and cubes to introduce students to the idea of irrational numbers. Three reproducible worksheets cover the history of the square root of 2, the discovery of irrational numbers and the Pythagorean Theorem. Contains 11 geometric solids made from soft, durable, and nontoxic foam. Cubes measure 2-1/2" per side.
　
Unlike any other balance, this balance makes it possible to physically show that -1<0. Weights placed in the outer pans represent negative integers and those placed in the inner pans represent positive integers. Students use the balance to derive the rules for working with signed numbers, solving linear equations, building identities, and modeling systems of linear equations. Ideal for small group work, the sturdy 17" plastic balance comes with four plastic pans, a set of plastic weights, and four plastic canisters. Detailed instructional booklet included.
　 　

S-1987T Magnetic 3D Rainbow Fraction Cube and Sphere磁性立方體球體分數

S-7975T Proofs of Pythagoras 畢氏定理
Set of 36 fraction pieces. Fraction representations of one whole, halves, thirds, and fourths for the cube and sphere. Magnetic so they stay together when assembled. Cubes and spheres measure 3". Comes with a labeled storage tray.
　
Explore five proofs of the Pythagorean Theorem. Three transparent plastic models (including two using triangles) project on the overhead and are a hands-on way to demonstrate that a2+b2=c2. Includes teaching notes.
　
　 　

S-1312T Getting Into Solids Pyramids線狀幾何錐體組

S-2681T Getting Into Solids Prisms Set線狀幾何柱體組
 Allows students to examine three-dimensional figures from various perspectives, giving them the chance to get inside both visually and physically to view and touch normally hidden lines and in turn gain a better foundational understanding about the figures. The durable, high-quality plastic bases have etchings and color codings to correspond with the edges and apothem. Set includes: six 10" H, durable, high-quality plastic bases (square, rectangle, circle, triangle, pentagon, and hexagon), six brass altitude rods, precut elastic strings in two colors, six string attachment caps, and assembly instructions, all in a handy storage package.
　
 Offers students the opportunity to get into each solid to see and touch normally hidden lines, thus gaining a clear understanding of three-dimensional figures. Includes two each of the following bases: square, rectangle, circle, triangle, pentagon, and hexagon. Includes brass altitude rods in two heights (which allows the construction of a cube, or a change in height of any other models), precut elastic strings in two colors, six string attachment caps, one sticky note pad, and assembly instructions.  10" Height
　

S-1311T Getting Into Solids Pyramids Book

S-2682T Getting Into Solids Prisms Book
Walks students through a step-by-step plan to draw all of the pyramidal solids in the Getting Into Solids™ set. Presents problems and worksheets for finding the surface area and volume of each of the shapes. Each of the six solids has six different worksheets, three each for surface area and volume.
　
Reproducible worksheets for finding the surface area and volume of regular prisms and right cylinders. As students work through pages they develop skills in which to logically organize their thought processes. 36 pages.
