Advent calendars for kids are a fun family holiday tradition, and the Costco LEGO Advent Calendar 2021 lineup has three great popular character themes! While the chocolate advent calendars are more traditional…these STEM activity advent calendar sets are way more fun, educational and healthy! The Costco LEGO Advent calendars are available this year for Christmas 2021 in Harry Potter, Star Wars and Avengers Super Heroes.

Each of these LEGO Advent calendars 2021 features 24 days of mini themed LEGO kits. Each kit builds a small piece of the scene you see featured on the box including the minifigures. Some days are very simple and others contain quite a few pieces. It’s a good mix of small building activities that kids can work on independently.

These are a great gift for LEGO loving kids and are suitable for younger kids as well as those just starting out on the “big kid” sized LEGO pieces. These are not duplo or megablok sized so they are recommended for older kids. Each Advent calendar has its own recommended age, but given how small each individual day’s is, there is low frustration compared to a standard size LEGO kit as it’s all complete in just a few steps. Our kids got their first LEGO Advent calendar at age 5 and really loved them and were able to follow the instructions and build them independently, play with them and set them up like a little holiday display.

We like to open each LEGO set up in the morning (my kids are crazy early risers!) and start the day with a little STEM mini activity. They only take a few minutes each but it’s fun to see what we get each morning and build out our “scene” with all the parts and pieces from the LEGO sets.

In previous years, Costco had a LEGO Friends Advent Calendar available, however it does not appear to be in the lineup this year for 2021 so far either online or in-store (as of 9/28/21).

Costco LEGO Advent Calendar 2021 are a great deal! And you can find all 3 versions of the LEGO Advent Calendars online and in-store.
