HCPSS Objectives:

• Identify multiplication as repeated addition, groups of sets, and arrays.
• Construct an array to represent a multiplication sentence.

• Demonstrate fundamental computer operations
• Demonstrate proficient (efficient and effective) use of input devices
• Demonstrate fundamental software operations (open and close software program and manage files and folders)
• Navigate common software features (such as drop down menus, shortcuts, tool bars, help menu)

· Practice responsible and appropriate use of technology systems, software, and information

Procedure – Day 1:

1. Have students log onto a computer and then meet you up front.
2. Read aloud from 100 Hungry Ants.
3. Discuss what is happening in the story that no matter how the ants marched they were always 100 of them.
4. Using some examples from the story model on chart paper model how we can write the ants were arranged in arrays. Record addition and multiplication number sentences to describe the array.

4. Repeat this several times and have students T-P-S number sentences for other examples from the story and record their answers on the chart paper.

5. Discuss concept of multiplication as adding groups of the same number.

6. Display Ladybug Arrays.kid activity on the projector. (Depending upon the technology skills of your students, you may need to model the steps needed to access the file)

7. Go over the directions with the students and check their understanding of what to do.

8. Have students go back to their computers and begin their work.

9. Circulate and monitor their progress.
