Explore some photographs of the space shuttle!

• Click Rockets & Airplanes. Then click The Space Shuttle.
• Scroll down and click See some great shuttle pictures.
• Click to make them bigger.
• Then solve the problems below.

1. Count the photographs in the first two rows. Write related multiplication and division sentences for this group of pictures.
   
   
   
   
2. Write related multiplication and division sentences for the whole page of shuttle pictures.
   
   
   
   
3. Peter and Juan want to make a collection of the space shuttle photographs. If they divide the photographs equally, how many photos will each get?
   
   
   
   
4. Look at the photograph called "Extravehicular Activity (EVA)."
   If an astronaut goes outside her spacecraft 3 times a day for 7 days, how many times does she go outside in all? Write the multiplication sentence. Then write a related division sentence.
   
   
   
   
5. If a shuttle orbits Earth 36 times in 4 days, and orbits an equal number of times each day, how many times does the shuttle orbit Earth each day?
   
   
   
   
6. Repair work outside a shuttle took 42 minutes altogether. If the astronaut worked on 6 different small jobs for an equal amount of time, how long did he spend on each job?
   
   
   
   
7. Vinny went to the hobby shop and spent $10.00 for 2 space shuttle models. Tasha spent $12.00 for 3 models. Who spent more on each model? How much more?
   
   
   
   
8. Christa, Melanie, and Kaitlin spent 15 hours over 3 days on a class project called "Extravehicular Activity (EVA)." If the girls spent equal time on the project, how many hours did each girl spend?

Today I explored a Web site that showed photographs of the space shuttle. I learned that the space shuttle is used to launch satellites and astronauts into space. Then I solved division problems about the space shuttle. I figured out that if a shuttle orbits Earth 36 times in 4 days, and orbits an equal number of times each day, the shuttle orbits Earth            times each day!
