It's difficult to keep technology out of young children's hands, and sometimes, it's not productive. Here are some ways technology can be educational and fun for the family.
3D Printing
A 3D printer is a great tool for kids to learn. They'll learn how a 3D printer works: how to insert filament, adjust slicer settings, which type of resin to use, and more.
Experiment with different filaments that glow in the dark, change color, conduct electricity, and even tones that mimic the appearance of silk.
Things at home break, and not always cheap to fix. If you can't find the part, or can't afford to order one with ridiculous shipping costs, have them make it!
Instead of spending money on toys, look up files to make action figures or dolls. Or make models of planets for science projects.

Coding
What better way to be ready for the digital age than to learn to code?
Python is still one of the go-to languages for beginners. It's easy to read, learn and use.
As long as we have the internet, JavaScript will always be needed.
JavaScript is the go-to programming language of the web. It's used on the front end of websites to make them dynamic and interactive.
Projects on Code.org and FreeCodeCamp are great resources for kids to start learning. All you need is a web browser!

Raspberry Pi
Raspberry Pi offers a ton of different projects to work on. One of the simplest Raspberry Pi projects you can finish is using it as a desktop PC.
It can handle most basic tasks such as surfing the web, playing videos, and some basic programming.
If the kids are into gaming, a Raspberry Pi is great as a retro gaming machine. Since it's powerful enough, it's suitable to serve as a full-size arcade machine.
Many classic gaming platforms can be emulated, from MS-DOS and 16-bit consoles to the Commodore 64.
Many of the Raspberry Pi projects go hand-in-hand with coding skills, so kids can learn multiple skills at once.

Build a PC
Building a PC is the best way for children to understand each part of a computer, and understand that technology isn't cheap!
It will teach them how to properly connect the components, cable management, how to install an operating system, and other software.
When your family is old enough to need a computer for daily school work, it's easy to buy something cheaper for basic use.
But if you can budget out a PC to build together, your kids will acquire skills and have a PC that lasts longer.

Wrapping Up
Consider getting a 3D printer to teach your family designing and modeling skills. 3D printing is a lot more affordable now, so the barrier to entry is low.
Coding languages are almost as important as learning a foreign language. It's a great skill for kids to practice every day.
A Raspberry Pi is a great way for kids to learn multiple skills. Turn a Raspberry Pi into a 3D print server!
Learning how to build a PC from scratch is a skill kids can use for a lifetime; think of how much money they'll save on repairs and customer support!
