Content:

This lesson uses PowerPoint and group work to reinforce the use of operations and how operations relate to one another.

Benchmarks:

NM-NUM.3-5.2

• Understand the meanings of operations and how they relate to one another
• Understand various meanings of multiplication and division
• understand the effects of multiplying and dividing whole numbers
• Identify and use relationships between operations, such as division as the inverse of multiplication, to solve problems
• Understand and use properties of operations, such as the distributivity of multiplication over addition.
• Know how to exchange files with other students using technology
• Collaborate with a classmate using a variety of technology tools to plan organize and create a group project

Learning Resources and Materials:

• Computer workstations with PowerPoint and the ability to upload flash drives.
• Also the room needs to be able to project an image from a computer onto a screen large enough for a whole class to see (such as the ones used for overhead projectors).

Development of Lesson:

• Introduction:
Start by going over the basic functions of how to use PowerPoint with your students. Show students how to: fill-in information, add a new page, add a picture from clipart, and change the color of the background. Also discuss with students that when using a computer “/” means divide and “*” means to multiply.
• Methods/Procedures:
Start by dividing the students into groups of three and assigning each group an operation (either multiplication, division, addition or subtraction). Next go around to each workstation and show the students how to use a flash drive to load an example PowerPoint presentation that gives them the steps on how you want them to make their presentation, as well as an example presentation, and show the students how to open the file to view it. Make sure to remind the students that all they need to do to go to the next slide is to click the screen. Instruct students that after they are done viewing the presentation, they may open a new PowerPoint window and begin their own PowerPoint presentation. Also remind the students that they may go back at anytime and review the example PowerPoint if they need to. As the groups finish, show them how to save their presentations to a CD-R (you may also use a floppy disk if the computers that you are using are not able to write CDs). After all of the groups are done, have the groups take turns presenting their PowerPoint presentations to the class by having them use their CDs to transfer their presentations to a computer that is able to be projected onto a screen (much like an overhead projector works) for the whole class to see. Students will then be able to take home their presentations and show them on their home computers to their families.
