Brenda wants to know if the Raspberry Pi is a computer that her grandkids could learn with. Leo says absolutely. It can not only teach kids how computers work but teach them how to program. You can run Windows on it; you can run Minecraft on it. It's an excellent computer for kids, and it's only about $35. But that's only the board. It's not the computer monitor, keyboard, or mouse. Check out ADAFRUIT; they have a great starter pack for around $100. Can you block websites? Leo says not on the Raspberry Pi, but you can do it from the router. Check out Disney's Circle.
