Tangrams

Subject: Math
Topic: Geometry
Strand: Planes (tangrams)
Grade: 3-5

How would I use this in my classroom:
This site would be great for a SMARTBoard (but could also be used on computers for individual work). The students would be able to actually move and manipulate the shapes to form another shape from the geometric figures. With the use of the SMARTBoard, the students would be able to do the activities with the pens or their fingers to be active in their learning. As a supplement to this site I would use actual manipulatives.

Curriculum Connection:
Math: Geometry: Planes: G-16 combine two-dimensional geometric figures to make other figures



Information from the site:

Tangrams is an ancient game that originated in China. There are literally hundreds of recognizable shapes that have been made by combining the seven smaller pieces (called "tans"). Our tans can be dragged and rotated, snap together when placed close enough, and when selected, the color of a piece can be changed. There are fourteen shape buttons below the workspace, some of which are provided with hints. Young children may profit from simply moving pieces around and fitting them together in various color combinations. After some initial experience, they may want to activate all the hints to get an outline for each piece in the desired construction. Making the pieces fit the outline, using the Flip button if needed, is a useful exercise in control and manipulation. As students gain confidence and experience they can tackle more substantial challenges from the shapes given.
