Attribute Trains - A Virtual Manipulative
Practice completing patterns of shapes, numbers, or colors. Complete the pattern by dragging blocks onto the train.
If a block does not belong where you drop it, it will return to where you picked it up. Press New Problem to start a new train.
Pattern Blocks - Exploring Patterns Through Shapes - Virtual Manipulative
This program is easy to use. As you can see from the panel below, the colored shapes on the left, are the pattern blocks or manipulatives which can be clicked on to magically make new shapes. This shapes can then be dragged into the working area. There is no limit as to how many shapes you can make and drag out.
(There are more instructions underneath the manipulative.)
Pascal's Triangle - A Virtual Manipulative
Pascal's Triangle is a triangular arrangement of numbers constructed in such a way that every number in the interior of the triangle is the sum of the two numbers directly above it. It has a great many applications, including the coefficients of the expansion of a binomial expression or the number of ways to choose m objects from a group of n indistinguishable objects, or calculating the probabilities involved in flipping coin. This manipulative allows you to view a number of patterns in Pascal'
Congruent Triangles - A Virtual Manipulative
You are given three red segments and three blue segments, with each blue segment matching a red segment. Each segment can be dragged and rotated. Drag the end point of one segment to coincide with the end point of another segment of the same color; they will snap together. Then drag the end of the third segment of the same color onto a free end of the first two. By rotating the outer segments of your three, you should be able to get their free ends together.
Pinwheel Tiling – A Virtual Manipulative
This manipulative allows tiling the plane with Pinwheel Triangles. A Pinwheel Triangle is a right triangle with one leg twice as long as the other. Five Pinwheel Triangles can be combined to form a larger Pinwheel Triangle, called a super-tile, with the original triangle occupying the interior position. There are more instructions on the right side of the Java applet.
Right Triangle Solver – A Virtual Manipulative
Practice using the Pythagorean theorem and the definitions of the trigonometric functions to solve for unknown sides and angles of a right triangle. There are more instructions on the right side of the Java applet.
Triangle Solver – A Virtual Manipulative
Practice using the law of sines and the law of cosines to solve for unknown sides and angles of a triangle.
Analog and Digital Clocks - A Virtual Manipulative
Time - Analog and Digital Clocks – Interactively set the time on a digital clock and an analog clock. There are easy-to-understand instructions to the right of the manipulative.
Time - Match Clocks – A Virtual Manipulative
The problems in this clock manipulative all ask you to identify the time on one of the clocks and then to make the time on the other clock match the time on the first. There are easy-to-understand instructions to the right of the manipulative.
Elapsed Time - A Virtual Manipulative
What Time Will It Be? – Answer questions asking you to indicate what time it will be before or after a given time period. There are easy-to-understand instructions to the right of the manipulative.
Fill and Pour - A Virtual Manipulative
Your goal is to fill one container with the requested amount of liquid by filling, emptying, and pouring between the two containers. There are easy-to-understand instructions to the right of the manipulative.
How High? - A Virtual Manipulative (Volume)
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

Virtual Frog Heart Dissection
This 45 second video demonstrating the dissection of a frog heart. It demonstrates how cuts are made to the pericardium, truncus arteriosii and the caudal vena cava to remove and open the frog's heart to see its internal structure. This is a small clip from the Digital Frog Virtual Disssection program.
Introduction to the Dissection of a Virtual Frog
This short, 46 second clip demonstrates initial three cuts made to the skin of the body cavity to reveal the frog's muscles. This is a small clip from the Digital Frog Virtual Dissection program.
Venn Diagrams - A Virtual Manipulative
This virtual manipulative represents three sets as overlapping circles. You can use it to represent set operations such as intersections, unions, and subsets.
The goal for each exercise is to shade the portion of the diagram corresponding to the given set.
You may begin by shading one or more entire sets (A, B, or C) and then clearing portions. When you have only the desired portion shaded, click the Check button.
