Students will use square tiles to help them understand the concept of square numbers.
A squared number is a number that is a result of multiplying an integer by itself. Any squared number of counters can be arranged in a square array. You can write each squared number as a product using an exponent.
42 = 16
“Four squared equals sixteen, or four to the second power equals sixteen.”
1. Demonstrate a positive learning attitude toward mathematics.
2. Become mathematical problem solvers.
3. Reason mathematically.
4. Communicate mathematically.
5. Make mathematical connections.
6. Represent mathematical situations.
Invitation to Learn
Read the book Sea Squares. Ask: “What are squared numbers?”
Instructional Procedures
Possible Extensions/Adaptations/Integration
Color in the square numbers on a multiplication chart. Look for patterns (e.g.,
the square numbers are on a diagonal, the square numbers increase by 2 each
time, etc.) Use the calculator to further explore square numbers.
Homework &Family Connections
Ask students to look for arrays at home and record them. Which arrays form a
perfect square? Some students may want to bring in arrays to show the class.
Journal: Have students explain what square numbers are. Use pictures, words and numbers to explain what 52 is.
