If you find yourself asking questions like:
“How long is this going to take?”
“How many people are in line?”
“How much is this going to cost?”
Chances are good your family is ready to explore Estimation 180
Estimation 180 taps into this natural curiosity to quantify the world around us, providing both students and teachers with opportunities to build number sense one school day at a time.
Andrew Stadel, the creator, describes the process:
How many sheets remain on the smaller roll of toilet paper?
Need a clue? Head to Day 28 for the full roll.
The video answer can be found here.
There might be days you can’t do these Estimation 180 challenges at the table because you’re on the road. Use the fast food drive-thru as yourTable Talk opportunity. If there's a long line, simply ask, “How long is this going to take?” Go around the car making estimates and then start the timer. The winner gets a free ice cream cone.
