S2739T Advanced Geometric Shapes 15 幾何形狀

S2999T 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 handson 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 23/4" W x 4" H.
Includes eight geometric solids made from soft, durable, and
nontoxic foam. 




S2998T VisuAlgebra Blocks 
S2441T 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 problemsolving skills. Two reproducible
worksheets cover measuring and calculating the volume of
rectangular solids and provide an introduction to cubic numbers.


S3000T The Irrational Puzzle

S7821T FourPan 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 3D 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 21/2" 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. 



S1987T Magnetic 3D Rainbow Fraction Cube and Sphere磁性立方體球體分數 
S7975T 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 handson way to demonstrate that a2+b2=c2. Includes
teaching notes. 




S1312T Getting Into Solids Pyramids線狀幾何錐體組 
S2681T Getting Into Solids Prisms Set線狀幾何柱體組 


Allows
students to examine threedimensional 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, highquality plastic bases have etchings and color
codings to correspond with the edges and apothem. Set includes:
six 10" H, durable, highquality 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
threedimensional 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.

S1311T Getting Into Solids Pyramids Book 
S2682T Getting Into Solids Prisms Book 


Walks
students through a stepbystep 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.
