Math on Mars
Imagine you're an astronaut on Mars, where the gravity is much weaker than on Earth. You can jump much higher, but you also have to be careful not to float away! If you jump on Mars, you'll stay in the air for much longer before coming back down. Let's see how that affects our math.
Wee Ones
If you see 2 red Mars rocks and 3 green Mars rocks, how many rocks do you see in total? Count them all!
Little Kids
If you can jump 3 times in a row on Earth before getting tired, but you can jump 10 times in a row on Mars because it's easier, how many more jumps can you do on Mars?
Big Kids
On Mars, you can jump 3 times as high as you can on Earth. If you can jump 50 centimetres high on Earth, how many centimetres high can you jump on Mars?
The Sky's the Limit
The ratio of gravity on Mars to gravity on Earth is about 3:8. If a robotic rover weighs 400 kilograms on Earth, what is its weight in kilograms on Mars?
