WHAT IS A 3-D PENTOMINO PUZZLE?

The name pentomino is taken from the greek word penta,

meaning “five,” and domino meaning two squares joined

edge to edge. 3-D Pentominoes are Learning Resources’

updated version of this classic geometric puzzle consisting

of 12 unique pieces. Each piece is formed by joining five

identical cubes edge to edge. The 12 pieces resemble the

letters of the alphabet. They are listed below:

BRAIN-TWISTING FUN FOR KIDS AND ADULTS!

Filled with more than 50 puzzles, this booklet will get you

started on mastering the mysteries of the 3-D Pentomino

Puzzle. As puzzles are solved and new patterns are created,

an intuitive understanding of geometric and spatial

relationships naturally develops. 3-D Pentominoes sharpen

math and thinking skills through hands-on play!

The puzzles provided are presented by level of difficulty.

Skill Level Number of Pieces Used

Mildly Perplexing Puzzles Level 1 2

Brain-Twisting Puzzles Level 2 3

Mind Boggling Puzzles Level 3 4

Many of the puzzles may appear simple at first --- but

don’t be surprised. Learning to see and solve problems

three-dimensionally takes practice. Use the yellow sides

of the pentomino pieces as visual clues. Some puzzles

have more than one solution. Just in case you’re stumped,

solutions showing how the pieces go together are found

on pages 17 to 23.

THE SUPER CHALLENGE

For expert puzzlers, we’ve included a super challenge: build

a 3-D rectangle using all 12 pentomino pieces. Side views of

the completed puzzle are provided as hints.

GOING FURTHER

Create a personalized library of puzzles using 3-D

Pentominoes. Kids like creating animals or things from the

3-D pieces. Younger children will enjoy using the pieces to

fill flat outlines of animals like elephants or ducks. Outlines

can be traded with friends.

Encourage artistic creativity by tracing around a pentomino

piece and creating a pattern or design. Move the block and

trace around it again. Continue the pattern until the entire

page is filled. You can also try to trace around multiple

pentomino pieces. The resulting masterpiece can then be

colored and framed!

Note: You can use the back of this booklet as a guide to fit your pieces

into the box for storage.
