If you’re looking for a set to support STEM learning, we’ve identified five great ones where we think the best DUPLO set for 1-year-olds is LEGO DUPLO My First Fun Puzzle; and our top choice when it comes to toys for toddlers is LEGO DUPLO My First Number Train

We’ve chosen these sets because they are both simple and versatile STEM learning toys, supporting math, building, and counting skills, yet they are enough to encourage and reward creativity. They can also help with the transition to traditional LEGO since they have minimal specialty pieces and use the same building principles where the blocks make up the shapes.

LEGO DUPLO My First Fun Puzzle 10885 Building Blocks (15 Pieces)

The LEGO DUPLO My First Fun Puzzle Building Blocks is a great choice for younger kids. With bright colors, simple but fun animal designs, and a tower-building theme, this set checks all of the toddler fun boxes while offering valuable STEM learning in the process. This set is great for encouraging fundamental math concepts like categorizing and counting. 

Another great feature of this toys is that all of the set’s pieces are rectangular blocks. Your little one can explore putting together different colors and creating fun new creatures, taller towers, or something an adult could never dream up. This is a great starter set that can kick off a new DUPLO collection or or add fun colors and patterns into an existing collection.

LEGO DUPLO My First Number Train 10847 Learning and Counting Train Set Building Kit and Educational Toy for 2-5 Year Olds (23 Pieces)

The LEGO DUPLO My First Number Train is our top choice for toddlers. This set has a fun moving train, colorful blocks with numbers 0-9, plus child and cat figures. It’s a great educational toy offering fun experiences in engineering, math, driving, and reading.

Like our top choice for 1-year-olds, we also love that it’s a relatively simple set that can be put together in many different ways while also integrating with existing (or future) DUPLO sets.

LEGO DUPLO My First Bricks 10848 Colorful Toys Building Kit for Toddler Play and Pretend Play (80 Pieces)

The LEGO DUPLO My First Bricks – Building Kit for Toddler Play and Pretend Play is a really fun starting point for any young child’s STEM toy collection. This set is quite a bit bigger than our first two choices, which could make it a bit intimidating for younger children. But it comes with idea cards that give kids a starting point to help them learn how to build realistic-looking objects with LEGOs. 

Because this set isn’t themed, it offers a lot more opportunity for creativity than may sets, which is a great learning outcome. We also love that the idea cards are simple and recognizable objects, making the process fun and accessible.

LEGO DUPLO Large Playground Brick Box 10864 Building Block (71 Pieces)

The LEGO DUPLO Large Playground Brick Box is another great educational toy for the young one in your life. If your toddler is anything like mine, they LOVE the playground! This set lets kids design the playground of their dreams – complete with slides and a bouncy car ride – and then let their little lego buddies play all day! 

Little ones can learn to make the structures in the photos, and then get creative about how they are connected. While having fun and getting creative, they’ll be playing architect, engineer, and physicist.

Animal Bingo Game for Shape and Color Recognition by LEGO Education DUPLO

The Animal Bingo Game for Shape and Color Recognition by LEGO Education DUPLO is a fun set for interactive play with older kids, groups of kids, or adults and children. This set has a bit more structure if playing the game, but it still leaves lots of room for creative play and thinking.  

This particular set hits a bunch of STEM concepts, especially math and science themes. It’s a great introduction to matching colors and shapes, and following a guide to build a specific shape. Because the shapes themselves are animals, the set also offers opportunities for kids to learn about biology. And like our other recommendations, the pieces will integrate well into existing DUPLO collections.

What to Consider When Buying a LEGO DUPLO Set for Your 1-Year-Old or Toddler


Factor 1: Simplicity and Versatility

In researching DUPLO sets for this article, I found that there are sets that are mostly bricks that can be made into shapes, and there are sets with tons of specialty pieces that make a specific object. While both certainly have value, and the child’s interest should always come into play, I tend to think that a simpler set, with fewer specialty pieces, will be fun for longer, inspire more creative thinking and playing, and grow with the child.

Factor 2: Child’s Interests

LEGO makes themed sets for everything: movies, objects, habitats, and so many vehicles. If you know the child you are shopping for has a specific interest, it’s almost a guarantee that there is a set aimed at that topic.

Factor 3: Child’s Age

Smaller children may be intimidated by large block sets that don’t have obvious outcomes. I’ve observed this with my own toddler, and would recommend starting with smaller sets (like the one we recommend for 1 year olds!) with younger kids.
