Texas Instruments: Surround and Be Found! Triangular Areas, That Is!
In this activity, students use the Geoboard to determine the area of triangles using the surrounding rectangle technique. They also develop and use formulas to determine the area of triangles. [Requires Adobe Reader.]
Texas Instruments
Texas Instruments: Get to the Point! Coordinate Geometry!
In this activity, students use the Geoboard to determine the area of any polygon using coordinates.
Texas Instruments
Texas Instruments: Classifying Angles
Students will create a variety of angles using the Geoboard APP. The teacher will use Screen Capture to display the angles created by the students and will lead a discussion on whether the angles are acute, right, or obtuse.
Texas Instruments
Texas Instruments: Cross Fencing Pastures
In this activity, students use the Geoboard to determine the areas of polygons by dissecting them into parts that are squares, rectangles, and triangles.
Texas Instruments
Texas Instruments: Move Along Little Vertex
In this activity, students use the Geoboard to determine the area of triangles having the same base and same height.
Texas Instruments
