## Act 1

1. How long will it take to knock down all the dominoes?

2. Write down a guess.

## Act 2

3. What information would be useful to figure this out?

4. Write down some questions you have in your head right now.

## Act 3

**TEKS**

6.5(A)

represent mathematical and real-world problems involving ratios and rates using scale factors, tables, graphs, and proportions

Is there anyway you can share the process to solve this? I tried using the given information to find a solution, but my answer was not what ACT 3 had as an answer.

Thanks

Glenn

Hey Glenn! I just tried as well, and the answers did not come out the same.

I set up a proportion:

1.06/12 = x/119

x = 10.512

My guess is that the rate increases as the dominoes pick up more steam. Not sure I have a good answer, but this seems to put us in an interesting situation! Maybe it can lead to a good conversation about how real life and math models don’t always align?
