The math applet that I chose for the Pre K – 2 grade level included: Developing Geometry Understandings and Spatial Skills through Puzzlelike Problems with Tangrams: Tangram Puzzles. The main objectives for this applet included the ability to describe figures, along with the ability to see the formation made when the shapes are changed through the buttons located in the applet. The applet has the student use different shapes to fill in an outlined image. This type of task should be very simple for the students to understand and something that they could do on their own without much instruction. The students will have a better understanding of geometry when the time comes because of the background that they received with these different shapes. The teacher can create student discussions by asking them certain questions pertaining to the applet functions. A good example of this would be, “what happens to the shape when you flip it?”. An easy way to assess the students would be to see if they were able to identify and use all of the shapes to fill in their respective outlines. All in all, this is a good applet for the younger students and is a good stepping stone that will eventually lead to higher learning.
