I'm taking these straight from Dan's post:
- Ask every student to guess how long it'll take to fill up the water tank before you explain to them how to find the volume of a prism. (See: lots of other examples just like that.)
- Ask every student to draw a triangle with given constraints before you explain why those constraints result in the same triangle.
- Ask every student to try to draw a line that's parallel to another given line before you explain to them how you can determine whether or not two lines are parallel.
- Ask every student to guess the age of an individual before you explain the definition of absolute value and use it to figure out who guessed closest.
- Ask every student to take and submit a photo of stairs before you show your own photo and explain how we can figure out which is steepest.
- Ask every student to write down two numbers that add up to five before you explain why our pairs all seem to show up on the same line.
These are all ideas I can implement in my classroom on my own- without the technology. Eventually, this will be created and become the norm in education. But why wait? Let's teach better math now.
What other ideas can we come up with that creates an intellectual need for students to learn more?
