What information would you need to answer these questions?

How many meter sticks does it take to equal the mass of the Moon?

If all of these meter sticks were lined up end to end, would they reach the Moon?

How many meter sticks does it take to equal the mass of the Moon? Explain or show your reasoning.

Label the number line and plot your answer for the number of meter sticks.

If you took all the meter sticks from the last question and lined them up end to end, will they reach the Moon?

Will they reach beyond the Moon? If yes, how many times farther will they reach? Explain your reasoning.

How many light years away would the meter sticks reach? Label the number line and plot your answer.

Here is a problem that will take multiple steps to solve. You may not know all the facts you need to solve the problem. That is okay. Take a guess at reasonable answers to anything you don’t know. Your final answer will be an estimate.[br][br]If everyone alive on Earth right now stood very close together, how much area would they take up?

[size=150]In 2016, the Burj Khalifa was the tallest building in the world. It was very expensive to build.[br]Consider the question: Which is taller, the Burj Khalifa or a stack of the money it cost to build the Burj Khalifa?[/size][br][br]What information would you need to be able to solve the problem?

Record the information your teacher shares with the class.

Answer the question “Which is taller, the Burj Khalifa or a stack of the money it cost to build the Burj Khalifa?” and explain or show your reasoning.

Decide what power of 10 to use to label the rightmost tick mark of the number line, and plot the height of the stack of money and the height of the Burj Khalifa.

Which has more mass, the Burj Khalifa or the mass of the pennies it cost to build the Burj Khalifa?

What information do you need to answer this?

Decide what power of 10 to use to label the rightmost tick mark of the number line, and plot the mass of the Burj Khalifa and the mass of the pennies it cost to build the Burj Khalifa.
