Lock Quest: The Rocket Key

The rocket hatch is open!

The hatch swings open and Zip hops into the pilot seat. Three, two, one, liftoff! Your team waves from mission control as the rocket climbs out of sight.

You are now a Lock Master. Go tell your teacher!

Your mission

Zip the frog is an astronaut, and the rocket hatch is locked five ways. Division means sharing equally, or splitting into equal groups. 24 shared by 6 is 4 each. Sometimes it does not come out even, and a few are left over. Division is also multiplication backward: if 6 times 4 is 24, then 24 divided by 6 is 4. Zip hid the clues all over the launch pad. Look closely and work together.

How to crack a lock

• Pick any lock from the menu at the top. You can solve them in any order.
• Read every clue before you start. One clue alone is never enough.
• Use scratch paper. Draw pictures, make lists, and cross things out.
• Tap the buttons to build your answer. Then press "Try the lock".
• A lock will not tell you which part is wrong, so be sure before you try.
