This Earth Day logic puzzle is a unique way to teach Earth Day vocabulary to kids! Logic puzzles are a great activity to strengthen logical reasoning skills, boolean, and comparison skills while working with a series of selection statements.

Logic puzzles develop logical reasoning skills

Logical reasoning is the ability to analyze and make predictions about things or explaining why something is the way that it is.

Logic puzzles are a great way to use to emphasize the concept of logical reasoning by explaining why a word cannot fit in a certain space.

Due to the number of letters in each word, kids can speak to why each word goes in each space, which helps them to solve the puzzle.

How to solve the Earth Day Logic Word Puzzle

The best way to begin is to use look for a word length that only has one word. Why? Well, if there is only one word of any length left than it’s the only possible answer for the space.

Once you know some letters in the grid, then you can count how many letters long each space is (how many blocks) and compare it to the words remaining using the letters filled in from the previous word. 

Go slowly and think through your puzzle. Use a pencil! Some of the clues will not be helpful right away. Keep working through the list of words and go back.

You’ll find an answer key on the second page of the download as well as below!
