LEGO MINDSTORMS EV3 31313 Robot Kit with Remote Control for Kids, Educational STEM Toy for Programming and Learning How to Code (601 Pieces)

LEGO Mindstorms EV3

A LEGO creation for kids who are into programming and coding

If your kids are into programming and coding, you won’t get better than the LEGO Mindstorms EV3 robot kit. It’s just like regular LEGO, only much more advanced!

This is one of the more expensive options, but it’s certainly a quality product. Kids will love building their own robot then coding it to walk, talk, play games and shoot targets. Using a free EV3 programmer app on their tablet, coders use the intuitive drag-and-drop interface to control their creation. 

Your little engineers will be able to build five different robot models from this set, from the fight-ready Ev3Storm with its blasting bazooka and spinning tri-blade to the crawler-mounted Track3R who can use its tools in any terrain. The set comes with 601 pieces including color, touch and IR sensors and an infrared remote control is included. A pricier product, but if your kids are keen to learn more about robotics this could be a good choice.

Discovery Kids Mindblown Solar Robot Creation Kit

Real working robots with solar-powered motors that kids will enjoy

Robots are always cool, but I like the solar-powered engine on this one. The Discovery Kids Mindblown Solar Robot Creation Kit is pretty versatile and includes all the parts your kids will need to make a range of different working robots. There are instructions for 12 models, but kids are free to come up with their own designs.

There are 190 pieces in this set including moving and connecting parts like gears, plates, tires, and shafts. Their robots will be able to walk, float or roll!

Once they’ve built their robot, they just need a sunny day to charge up the solar-powered motor. Its solar panel powers the positive and negative cables and the robot will be up and about before you know it.

The instructions are clear and easy to understand, but even so, the robots are not easy to put together. Your 10-year-old will probably need some adult help to assemble their creation. Their fine motor skills will certainly get a workout.

Once built, the robots are fairly straightforward though and this kit should keep your robotic engineer busy for hours.

What to Consider When Buying a STEM Toy

Your Child’s Interests

10 Year Old girl playing with an engineering toy

Make your child’s particular interests your number one consideration when buying a STEM toy. There’s no point spending a lot of money on a chemistry lab set if your child has no interest in that area. Instead, look at what your child is passionate about and use STEM toys to encourage that interest. If they love to build, you might like to invest in a quality construction set. If rocket science is their thing, you could buy some great experiment kits.  There’s a lot of really good toys out there, so be guided by what your child loves to do.

Your Child’s Age

Always think about your child’s age and experience when you’re choosing a STEM toy to buy. The toy needs to suit their skill level – if it’s too hard they’ll lose interest fast and if it’s too easy they’ll get bored with it.

Most STEM toys have a suggested age range on the box so use that as a guide if you’re not sure. Even if a toy is designed for their age group, young children may still need some help from their parents, especially if they’re beginners. This is a perfect opportunity to develop collaboration and teamwork skills!


It’s very easy to break the bank when you’re shopping for a STEM toy. There’s a lot of toys on the market and some of them are quite expensive, so think carefully before you open your wallet.

Do you know your child is interested in this area of STEM or are you just gauging their interest? Is this a toy they will get a lot of use from or is it likely to have a short run then end up back in the box? Do you need a top of the range model or will a less expensive option be just as good?

You might decide that the STEM toy you have in mind is well worth the investment, but make sure you do your research before coughing up the cash!

Frequently Asked Questions

Tween girl playing with LEGO Mindstorms robot toy

What is a STEM toy?

A STEM toy is any toy that develops skills in the areas of science, technology, engineering, and math.
