Math Art Projects
Change to a numeration and place value activity. Inspired to make a cross-curricular math/art activity motivated by skyscrapers. Example: "My skyscraper is 5 432 ft tall", each number is a different tint or shade to connect number and colour value. Together, the class will have a city skyline.
Cute idea... good way to get them to learn square roots without them knowing it because they know the numbers under the post its! It is very inexpensive and not at all time consuming to make. The only problem I can think of with this would be the postit notes loosing their ability to stick onto the clock's face.
