It’s no secret that children are naturally curious about the world around them.

In order to succeed in today’s high-tech, competitive world, they will need the skills necessary to focus their curiosity and creativity to not only be aware of the technology that surrounds them but also how to use, manipulate, develop, and master it.

Sounds like a tall order when you gaze at your little one, right? That’s where the magic of STEM kits comes into play. 

What are the best STEM kits for preschoolers? Preschoolers will benefit from STEM kits that keep their interest in a fun, age-appropriate way and focus on developing the skills they’ll need to succeed in school, particularly fine-motor skills, critical thinking, creativity, and problem solving. 

We all want what’s best for our children, and providing fun, educational STEM toys that will inspire them to be the best they can be is a fantastic way to ensure that they’re off to a great start in life. 

When it comes to STEM kits, some are better than others. Read through my top picks for preschoolers to find a few that your child will enjoy.

What Are STEM Kits?

STEM stands for Science, Technology, Engineering, and Math.

For young children, STEM kits are specialized toys and project kits designed to teach one, several, or all of the STEM subjects in an interactive, fun way.

Because these learning experiences are cleverly disguised as toys, children may not be aware of how much they are actually learning.

They just know that they are having a good time.

However, with STEM kits children will be developing, nurturing, and improving critical skills that will serve them well when the time comes to start their formal education.

STEM kits focus on cultivating one or more of the following skills:

  • Creativity.
  • Critical thinking.
  • Fine motor.
  • Problem solving and inquiry.
  • Perseverance and patience.
  • Design thinking.
  • Logic and reasoning.
  • Visual spatial.
  • Productivity.
  • Engineering/building/construction.
  • Observing and analyzing.
  • Experimentation.

What to Look for in Preschool STEM Kits

While your preschooler may not be quite ready for a chemistry set or dissection station, there are plenty of age-appropriate STEM learning toys that are designed to not only entertain but to engage your child and kick-start a lifetime love of learning.

Toys That Hold Interest

No one knows your child’s likes and dislikes better than you do.

Focus on STEM kits that your child is sure to find interesting and will actively engage him or her for more than a few minutes.

For instance, if your child is constantly pulling out your canned goods to create towers, a STEM kit focusing on building design skills would be ideal.

Focus on Skills That Need Improving

Honestly consider your child’s strengths and weaknesses. Choose a STEM kit that will help develop skills that could use improvement, such as fine motor skills or problem solving.

Age Appropriate

Many STEM kits contain small parts that may pose a choking hazard for young children. Keep safety in mind as you make your selections.

Also, steer clear of kits that may be too advanced for your child. A frustrated child will quickly lose interest and may not want to even try the next kit you bring home.

On the other hand, if your child is already a whiz at LEGO toys, you might find that a kit labeled above his or her age range is more appropriate.
