Although it lays the foundation for the higher level concept of squaring a number, the sheet only tests on 3rd grade concepts of multiplication; therefore, it is great for 3rd graders and above. The sheet also involves geometry and area concepts that start in 3rd grade.
Needing scissors and glue, this one page sheet is ideal for visual and tactile learners. It requires students to look for patterns, write in math, and critically think.
The second page is the answer key. (And, of course, if one looks hard enough, most the answers are somewhere else on the page itself.)
Thanks and enjoy!
