How many objects are in the glass?
Photo Step 1:
Place your picture here. Make sure it is sized just the way that you want it – and that it fills as much of the screen as possible without covering the clues. You have the entire left half of the slide to work with so use as much of that space as possible. When you are satisfied with how your picture looks then copy it and paste it in the same location on the next slides.
Steve Wyborney
As the clues appear, use the information to narrow the possibilities to a smaller set. After each clue, use estimation again to determine which of the remaining answers is the most reasonable.

Write down your first estimate. After each clue, you’ll see if your estimate is still a possibility. After each clue, if it is no longer possible write down a new estimate – and be prepared to explain why you chose it.

A Three-Act Task is a whole group mathematics task consisting of 3 distinct parts:
Act 1 - Watch the Video
What do you notice?
What do you wonder?
I notice...
Describe what you saw or what happened
I wonder...
What mathematical questions could we ask?
How many times will the juggler be able to bounce the ball off a body part until it hits the ground?
Make an estimate that is too low.
Make an estimate that is too high.
After you determine a too low and too high estimate, make a final estimate and label this estimate in the appropriate location on the number line.
Act 2 - The Gift of Information
Solve: How many times will the juggler be able to bounce the ball off a body part until it hits the ground?
Show your work below and put the answer in the yellow box.
