Simple Lego Coding Activities for Kids.
My 4-year-old knows how to code. Okay, that isn’t entirely true. That would be awesome if he did though. He does know that coding is telling a robot or computer what to do. (Thank you, Blaze and the Monster Machines.) And while that is a simplistic definition of what coding is, he isn’t wrong. Coding is telling something what to do. While we usually think of coding as something complicated that goes on behind the scenes with computers, it is something we can start to teach to kids in a fairly simple manner. Legos are accessible and perfect toys for this. Let’s learn to code with legos.

Why Learn Coding?
Why should you start to introduce the concept of coding to your kids? Well, a big argument is that technology doesn’t appear to be slowing its progress any time soon. We are already an online society, and more and more parts of life are going online. Computers are everywhere and those are run by coding. Being at least familiar and somewhat comfortable with the ideas and terminology behind this field will make your child more open to learning more about it. They will feel as though coding is for them. That is key to opening up fields to all kids.

More than just the actual technology, coding teaches a lot of important skills! It teaches persistence, logic, focus, organization, and patience. Oh, and it helps with math and communication skills. Coding is so much more than just math. The math is important, but at the end of the day, you are trying to communicate when you program a computer. So this really is a skill that kids can use in all aspects of life.
The great thing about using legos to introduce coding concepts is that the activities can grow with your children. Start with the simple ideas and games to really lay the groundwork for what will come and you might be surprised with what your children can come up with!
The most basic level of this coding is learning your components. In other words, knowing how to sort your legos. Lego sorting gives toddlers the chance to practice their colors. Start with having your little one separate the bricks based on color. As they get better at that you can add in sorting the size of the bricks. This practices counting. It can be a bit tough for little ones as the bricks are small, but they can do it.
After you have sorted by one trait, just color or just number, try sorting by two traits. Color AND size. For example, can your child make a pile of all the red 4×4 bricks and the blue 2×4 bricks? It is tougher to have to look at two distinct characteristics at the same time.
The next level is recognizing and repeating patterns. Coding involves a lot of pattern recognition. In binary all information is relayed in ones and zeroes, so the computer needs to recognize the pattern and equate that to the meaning. So after sorting is done we need to work on patterns.
Start with simple patterns, things like ABAB. Build the pattern and ask your child to say it to you. Then ask if they can recreate it. This is recognizing the pattern. Let them try a few. After your child can copy the pattern ask if they can predict what is next and repeat the pattern. This is a little harder than just copying. It requires them to think through what has happened and what should happen next.
As your child gets better at this move onto more complicated patterns. Things like ABCABC or ABACABAC. Whatever you can come up with is perfect. This is also a perfect time for older and younger kids to work together. Have older siblings make patterns for their younger siblings to copy and predict what comes next. This is a great way to get kids at different levels working together!
Now that patterns are understood it is time to assign meaning to our patterns. An easy way to start this is to create a pattern that represents a letter in the alphabet. For example, a single red brick represents the letter A. Two represent the letter B, three C and so on. Using this code you can write out words and sentences using Legos!
The one downfall to this sort of simple code is that it gets really long. Plus when computers read code they need to know when a letter ends, meaning how do you know the information being relayed is one letter represented by a string of ten bricks or is it two letters of three bricks and seven bricks? One option to fix this is to create a break code. So if all our letters are represented by a series of red bricks we can insert a blue brick to show that letter is complete.
Another option that compresses a code a little more efficiently is to create patterns that all have the same parameters. For example, we can represent each letter of the alphabet using only 5 bricks with 2 different colors. This way a computer would know that each set of five bricks represents a letter without needing an additional divider.
I have put together a sample code for your kids to try. Have your children try to copy this code and make different letters. Can they make the alphabet? Can they spell out words? As your child gets better you can spell out messages to each other!
Once your child has mastered the code given, it is time to really step it up. Challenge your child to create their own code. The sky is the limit here. How can they use the Lego bricks to represent the letters of the alphabet? They can use a blank pattern sheet to color in and make their own pattern, but this is just one way to do it. Can they use six bricks to represent each letter? Can they create codes for whole words?
This is a fun way to explore your child’s creativity and really do some critical thinking to solve a problem. I used a blank letter code form and let Ben color it in to try to make his own code. (You can find a copy in my free printables section!) Your child’s imagination is the limit!

Coding is for Everyone
This is just laying the groundwork for coding, there is obviously a lot more to it. But these skills are important for kids and they can use them in daily life! The other important aspect of this sort of activity is that it makes coding accessible to kids. Sometimes STEM topics feel too far off, like they aren’t for us. That is so discouraging! Introducing ideas and terminology at a young age takes away some of the mystery behind these topics, which in turn takes away the fear to try them out. Kids can do what we think they can do, and what we encourage them to think they can do. And kids can code.
