Transformations - Reflection - A Virtual Manipulative
With this virtual manipulative you can create objects with pattern block pieces and explore Reflections as transformations of the plane.
When the manipulative loads, a triangle and its reflection are already placed in the workspace. There are more instructions to the right of the manipulative.
Transformations - Rotation - A Virtual Manipulative
With this virtual manipulative you can create objects with pattern block pieces and explore Rotations ("Turns") as transformations of the plane. There are more instructions to the right of the manipulative.
Transformations - Translation - A Virtual Manipulative
With this virtual manipulative you can create objects with pattern block pieces and explore Translations ("Slides") as transformations of the plane. There are more instructions to the right of the manipulative.
Transformations - Composition - A Virtual Manipulative
Transformations - Composition – Explore the effect of applying a composition of translation, rotation, and reflection transformations to objects. There are more instructions to the right of the manipulative.
Transformations - Dilation - A Virtual Manipulative
With this virtual manipulative you can create objects with pattern block pieces and explore Dilations of the plane. There are more instructions to the right of the manipulative.
Geoboard - A Virtual Manipulative
Use this virtual geoboards to illustrate area, perimeter, and rational number concepts. There are more instructions to the right of the manipulative.
Isometric Geoboard - A Virtual Manipulative
Geoboard - Isometric – Use this virtual geoboard to illustrate three-dimensional shapes. There are more instructions to the right of the manipulative.
Circular Geoboard - A Virtual Manipulative
Geoboard - Circular – Use circular geoboards to illustrate angles and degrees. There are more instructions to the right of the manipulative.
Geoboard - Coordinate – A Virtual Manipulative
Geoboard - Coordinate – Rectangular geoboard with x and y coordinates. There are more instructions to the right of the manipulative.
Iterative Fractals - A Virtual Manipulative
Using this virtual manipulative you may draw any of six iterative fractals. Each is created by using a random probability process. There are directions to the right of the manipulative.
Koch and Sierpinski Fractals - A Virtual Manipulative
The Koch Snowflake is obtained by beginning with an equilateral triangle, removing the middle third of each side, and replacing it with two sides of a smaller triangle. This process continues forever.
The Sierpinski Carpet is constructed by starting with a square, removing the middle ninth, removing the middle ninth of each remaining square, and continuing.
There are more instructions to the right of the manipulative.
Mandelbrot and Julia Sets - A Virtual Manipulative
This virtual manipulative allows you to examine and experiment with the infinitely complex structure of Mandelbrot and Julia Sets. There are instructions to the right of the manipulative.
Polygon Fractals - A Virtual Manipulative
Using this virtual manipulative you may draw polygon fractals. Each is created by using a random probability process. There are more instructions to the right of the manipulative.
Platonic Solids - A Virtual Manipulative
A Platonic solid is a polyhedron whose faces are identical regular polygons. The ancient Greeks were able to show that there are exactly five such Platonic solids. This virtual manipulative allows you to display, rotate, and resize Platonic solids. It also allows you to select vertices, edges, and faces, and observe that the number of vertices minus the number of edges plus the number of faces is always equal to 2 (Euler's formula).
Platonic Solids - Duals - A Virtual Manipulative
The dual of a Platonic solid is another solid inside the first. The vertices of the inner (dual) Platonic solid are the center points of each of the surfaces of the outer Platonic solid. There are more instructions to the right of the manipulative.
Platonic Solids - Slicing - A Virtual Manipulative
Discover shapes and relationships between slices of the platonic solids. This virtual manipulative displays a Platonic solid on the left and on the right the outlined cross-sectional slice formed by a plane cutting through the solid. There are more instructions to the right of the manipulative.
How High? - A Virtual Manipulative
Learn about conservation of volume by pouring a liquid from one container to another container with a different dimensions:
Choose the shape of container to use by clicking on one of the shape options. The rectangular base is probably the easiest to work with at the beginning. The container on the left appears, partially filled with a liquid. You are to predict (or guess) how high will liquid go when it is poured from the container on the left into the one on the right. Drag the arrow next
Space Blocks – A Virtual Manipulative
Space Blocks – Create and discover patterns using three-dimensional blocks. User can add blocks, rotate and connect blocks. There are more instructions to the right of the manipulative. Activities and standards can be accessed by clicking at the top of the manipulative workspace.
Tessellations – A Virtual Manipulative
Tessellations – Using regular and semi-regular tessellations to tile the plane. There are directions to the right of the manipulative. The learner can use this virtual manipulative to explore which shapes tessellate and which do not.
Attribute Blocks - A Virtual Manipulative
Practice sorting blocks by color, shape, and size. The blocks inside the oval are the same color, shape, or size. Drag blocks that belong with them to the middle and then press. Check to see if you are correct. Press New Problem for a new set of blocks.
