Lesson Plan - Get It!
Do you keep your clothes in a dresser? Or do you have a shelf or cubby where you keep your toys? Skip back to your bedroom or playroom and count how many drawers or shelves you have. Take a picture in your mind of what the dresser, shelf, or cubby looks like. You've just begun a math adventure!
Did you take a mental picture of your dresser or shelving unit?
Now, take a minute to draw the dresser or shelf on a blank sheet of paper. It will probably look something like the picture below:
This is called an array. Arrays are tools you can use to make it easier to count and add. When you are older, you can use an array to help you multiply. An array is made up of rows and columns.
Have you ever sat in a row, maybe at a movie theater, on a bus, or at a sporting event? When you sit in a row, it is easier to see things. Rows also create organization.
Rows always go across.
Columns go up and down to help support the array, just like columns in a building help support the roof.
