I had a math class with third graders of which we discussed money I told them about virtual and real money of which I was very shocked and happy that they had knowledge about Bitcoin.
However we ended the class after we had spoken alot about Bitcoin they were soo happy and loved the class also
Like wow being with the kids was a nice time for them and I to get to know Bitcoin better look forward to having a class with them next week
You did not specify the third grader in question. third grade of elementary school, third grade of junior high school or third grade of high school.?
I'm assuming they are around 7 or 9 years old (third grade of elementary school), it's a good idea to introduce Bitcoin to them at an early age. There is a need for regeneration in Bitcoin technology and it will make them understand Bitcoin much more if you continue to provide understanding to them.
The way you introduce Bitcoin to them on the sidelines of math lessons can make their minds fresher, at least they can relax a little with the additional knowledge you present. What if you make extra study hours or special meetings outside of school activities, I think you can educate them further because you have more time to explain Bitcoin to them.
