CC:  On a diagram of a backyard that measures 28 meters across, have students draw a fence across the lot, placing fence posts every 2 meters. . On a diagram of a backyard that measures 28 meters across, have students draw a fence across the lot, placing fence posts every 2 meters. This division problem does not consider the width of the posts. They are simply vertical lines, as in a chain link fence. Ask, How many fence posts will the students need to draw? (15 fence posts)  Then, starting with the first post, have them add shrubs in front of the fence, every 4 meters. Ask, How many shrubs will be planted? (8 shrubs)

For a challenge, this word problem can be extended to include the width of the fence posts, as with wooden posts.

Example:  A 46-foot lot with 12-inch fence posts placed 2 feet apart (16 fence posts).
