Recently, the third graders have been learning about multiplication arrays. Mrs. Parris and Mrs. Archer brought their classes into the computer lab to design an “Array City” with “buildings” that represented multiplication problems.
We used Keynote on our Mac Mini computers to make our pictures (although this lesson would also work on iPads). I used April Requard’s iTunes U Course: Array City in Keynote for inspiration. I simplified the lesson by using tables to make our buildings. Students learned how to adjust the sizing of the tables to match the multiplication problem they were representing. They added text boxes to write the problems by each building. Then they used the formatting tools to change the line and the fill colors for each building. Finally, they took advantage of all the new shapes in Keynote to add roofs and decorations to their buildings.
Here is a gallery showing all the Array Cities. Click on the image to see a larger view.
