MEGA BLOKS for 3-year-olds: first guided builds
At three, children start following pictures to build a model, then breaking it up to invent their own. Our 3-in-1 sets are made for that jump.

From stacking to following steps
A three-year-old can look at a picture, find the matching block and put it in the right place. That is a big leap, and it is the idea behind our 3-in-1 builds: one box, one picture guide, three different models from the same blocks.
The blocks are the same big First Builders size, so the challenge is in the thinking, not in fiddly pieces.
Choosing the right 3-in-1
Pick by what your child already loves. Dinosaur fans get the Build & Chomp T-Rex; racers get the Build & Go Race Car; the Build & Enchant Unicorn and the Rolling Kitten suit animal lovers. Our 3-in-1 comparison lists the three models in each box.
Keep the big bag in play
Three-year-olds build bigger scenes: a house for the unicorn, a road for the race car. A building bag underneath the 3-in-1 sets gives them the extra blocks to do it, and everything clicks together.
When to move on
Many children enjoy big blocks well past their third birthday, especially alongside younger siblings. Our MEGA collector builds are a separate hobby for adults and older fans, with small pieces that do not belong near little ones.
Quick answers
Are MEGA BLOKS too babyish for a 3-year-old?
Not with the 3-in-1 sets. Following picture steps and inventing new models keeps big blocks interesting well into the preschool years.
Do 3-in-1 sets work with other MEGA BLOKS?
Yes. They use the same First Builders block as the bags, tables and vehicles.
How many models does a 3-in-1 set make?
Three, one at a time, from the same blocks in the box.
