Students will learn to add and subtract integers by creating electronic models.
Objectives
- Students will create a electronic manipulatives to model addition and subtraction of integers.
- Students will be introduced to the software Inspiration and techniques such as selecting and deselecting and object, resizing and object, moving an object, inserting a text box, entering, resizing and editing text, inserting, copying and pasting new objects, and changing/deleting objects.
- Students will gain a deeper understanding of adding and subtracting integers.
Procedure
- Students open Inspiration while teacher gives direct instruction on manipulation of the main idea "football". (moving, resizing, selecting, deselecting, deleting)
- Students go to the "Thinking" screen in the drop down tool bar by hitting the right arrow 3 times. Afterwards they select the "bubble" icon. They resize the icon to about 1/3 of the size of the visible screen.
- Students insert a text box and name their project "addition and subtraction of integers".
- Students then select math in the drop down bar and math again. They select the + sign, then copy it at least 8 times (teach them the shortcut). Do the same for the minus sign.
- Students then search for and insert a trash can into their project.
- Teacher gives a math problem and guides the students through putting plus signs in the circle and minus signs in the circle. When + and - pairs are removed, they are put in the trash can. Students solve the problem. This is repeated until the students can solve and model the problems independently.
- Students can then create problems for their peers to solve.

NETS Profiles for Technology Literate Students
-
Use a variety of media and technology resources for directed and independent learning activities.
- Use developmentally appropriate multimedia resources (e.g., interactive books, educational software, elementary multimedia encyclopedias) to support learning.
- Work cooperatively and collaboratively with peers, family members, and others when using technology in the classroom.
- Use technology resources (e.g., puzzles, logical thinking programs, writing tools, digital cameras, drawing tools) for problem solving, communication, and illustration of thoughts, ideas, and stories.
