Welcome! This listing features a one-of-a-kind cryptogram for earth science about igneous rocks. A cryptogram is a type of puzzle with an encrypted text. In this cryptogram, students will decipher a number code to reveal the letters to form the summary statement text about igneous rock. The header on both of the student pages has a horizontal letter-number assignment table. Students start out the activity knowing the number assignments for six letters. The entire message appears as a series of blank lines grouped into what will become words. There are numbers located under approximately fifty percent of the letter lines, some of which students start out knowing and most others they don’t. As students fill in the words of the puzzle with the help of a word bank table on the bottom of the second page, they will discover the number assignments for additional letters. Students can keep track of their number-letter assignment findings on the tables at the top of each page.
I assign this fun activity to my seventh-grade earth science students. It takes them approximately an entire class period to complete. This activity could also be used as a fun reinforcement activity in a high school earth science course as well.
This document will become editable upon conversion to Microsoft Word using an Adobe Acrobat Reader DC program. It includes a two-page answer key. Another bonus about this activity is the fact it is SUPER EASY TO GRADE!
