# Critical Thinking Activity #3 for Kids

Problem solving and critical thinking refers to the ability to use knowledge, facts, and data to effectively solve problems. Teaching kids to THINK is important in school and in life.  Kids need opportunities to think about things to make them “make sense”.  Critical thinking activity #3 gets kids to THINK.

Critical thinking activity #3 is perfect for a challenge activity, time filler, brain start, reward or extra credit. The first time I saw this problem, it took me some time to figure it out. I thought about it and then I started drawing it out to keep the possibilities straight. FINALLY, I got it. What will be your strategy?

Brooklyn has three jugs that are known to hold exactly 4, 9, and 12 gallons of water. The 12 gallon jug is full of water. There is no extra water supply. Can you figure out a way to use these jugs to each have only 4 gallons of water in each jug?

Once your student figures out the answer, challenge them to create their own example that can be solved in the same way.

Learning occurs in day to day activities. So, look for and create learning opportunities throughout your day. Stay safe and be well.

## Critical Thinking Activity #3 Answer is:

1. Fill the 4 gallon jug from the full 12 gallon jug. (that leaves 8 gallons in the 12 gallon jug).
2. Then empty the 4 gallon jug into the 9 gallon jug. (now you have an empty jug)
3. Go back to the original 12 gallon jug, that NOW has 8 gallons of water.
4. Fill the empty jug with 4 gallons of water
