Kids love making puzzles in all shapes and sizes, and they also love outdoor play. An activity that combines the two is one you’ll want in your toolkit.

Engaging kids in creative outdoor experiences helps build developmental skills while having fun in natural settings. In this activity, a standing tree trunk base can be used to make a life-sized nature puzzle. 

Our tree puzzle provides outdoor fun with STEAM along with fine motor and sensory play. 

STEAM = Science+technology+engineering+art+math

See how the principles of STEAM apply at the end of the post!

Tree trunk puzzle activity

Cut slices from wood stump to make a puzzle

Make the puzzle.

Cut three 2 inch (5 cm) sections from the tree stump, or more if preferred. Any number of pieces will spark curiosity in your early learner.

Once you have the puzzle pieces, place them on the tree stump in the original order.

Use characteristics of the tree stump to identify the order: the slant of the cut; the broken bark; the light and dark color of the wood.

  • Alternately, draw a line down the length of the trunk with a black marker before you cut the slices. This can serve as a guide to align the pieces after they cut from the trunk, so it’s easier for kids to place them back in their original positions.
