Crafting Connections: How to Design a LEGO Family Tree

Creating a LEGO family tree is a simple but powerful way to help children understand relationships, generations, and their place in a larger story while tapping into creativity and play. Also, look at my page From Simple to Spectacular: Easy LEGO Ideas for Everyone.

Family history can feel abstract to children when it’s limited to names and dates written on paper. Turning genealogy into a hands-on project makes it meaningful, memorable, and personal.

This activity works well across multiple ages, learning styles, and especially for visual and hands-on learners.

Studying family history helps children develop identity, empathy, and perspective. They learn that they are part of a larger story, one shaped by choices, challenges, faith, culture, and perseverance.

Using LEGO bricks removes pressure and perfectionism. There’s no “wrong” way to build a family tree. Instead, it becomes an evolving project that can grow year after year as children learn more.

This is one of those wonderful homeschool activities that blends play, academics, and meaningful connection, and it’s often remembered long after worksheets are forgotten.

Combine it with other activities like looking through old family keepsakes and pictures as well as doing further research on sites like ancestry.com.

LEARNING THROUGH FAMILY PHOTOS

Once the LEGO family tree is built, extend the lesson by looking through family photos together. Pull out albums, boxes of old pictures, or digital photo folders.

Encourage children to:

• Match photos to people on the LEGO tree
• Notice changes in clothing, hairstyles, or technology over time
• Ask questions about unfamiliar faces
• Compare family resemblances across generations
• You can turn this into a gentle storytelling session by sharing short memories or letting grandparents tell stories if possible. This builds listening skills, emotional connection, and historical awareness.

EXPLORE KEEPSAKES AND HEIRLOOMS

Family keepsakes are tangible links to the past. These might include:

• Jewelry
• Military medals
• Old letters or postcards 
• Baby books
• Bibles with handwritten records
• Tools, toys, or handmade items

Invite your child to examine one or two keepsakes and discuss them and how they fit into the family history.

Who did this belong to?
How old might it be?
Why was it important enough to keep?

Younger children can draw the item, while older students can write a short paragraph or create a LEGO display to represent it.

Researching Genealogy Beyond Your Home

As children grow more curious, you can introduce genealogy research tools to expand learning beyond what your family already knows. This is a great challenge for older children to take it beyond LEGO.

Helpful places to research include:

• FamilySearch.org (free and very homeschool-friendly)
• Ancestry.com (paid, but often free through libraries)
• Local libraries and historical societies
• Census records
• Immigration and ship passenger lists
• Church baptism, marriage, and burial records
• Old newspapers and obituaries

HOW TO DESIGN A LEGO FAMILY TREE

You will need:

• LEGO Baseplate
• Minifigures
• Brown LEGO bricks

For your LEGO family tree, start by deciding how many generations you want to include. I kept it pretty simple- younger children may focus on immediate family-parents, siblings, and grandparents, while older students can extend the tree further.

Design your minifigures to represent each person you want to display in your family tree.

If you don’t have a lot of minifigures, you can insert printed photos, certain color bricks, or handwritten names into the correct spots.

The next thing you are going to do is build a simple tree trunk by creating a vertical column of brown. You can use regular bricks or the flat ones, as I did.

You want to leave enough room at the top of the plate to place your top minifigures.

Then place horizontal pieces wide enough to hold 2 minifigures at the top, and work your way down to create the branches for each side and generation.
