We are planning a family vacation to NY and NJ this spring break! Thinking about stopping by Six Flags in New Jersey to try the Kingda-ka!

Spark wonder conversations with your children! What do you notice and wonder?

**W**onder: I wonder how many steps it would take to climb to the top of Kingda-Ka.

**O**bserve and research: Need to find data on the Kingda Ka Rollercoaster

**N**otice and Gather Information: It is 456ft tall. If I knew the size of steps, I can figure out how many steps to the top of Kingda-ka.

**D**o the Math: Assuming each step is 1/2 ft, 2 steps/feet, it would be 912 steps. 456*2=912 steps

**E**xplain & Evaluate: It would take 912 steps. That would be a lot of steps. If we were to increase the size steps to 10 inches, we can also revise our thinking.

**R**evise and Report: With larger steps of 10 inches, we could take 456*12inches=5472 inches. If we assumed the steps were 10 inches each, we would have about 547 steps up to Kingda Ka!

I also read that each step climbed burns 0.17 calories per stair climbed- so my next wondering is how many calories would I burn if I climbed the Kingda Ka?
