###### Math 4 - Act. 02: Square Numbers
 Curriculum Tie:Mathematics 4th Grade Standard 2Objective 1 Summary:Students will use square tiles to help them understand the concept of square numbers. Main Curriculum Tie: Mathematics - 4th GradeStandard 1 Objective 1Demonstrate multiple ways to represent whole numbers and decimals, from hundredths to one million, and fractions. Materials: square tiles Square Facts Worksheet crayons Sea Squares, by Joy N. Hulme. 2001 (Buena Vista Books, Inc.) Attachments Background For Teachers: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.” Intended Learning Outcomes: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.Instructional Procedures:Invitation to Learn Read the book Sea Squares. Ask: “What are squared numbers?” Instructional Procedures Have students use square tiles to build a 1 x 1 square, 2 x 2 square, 3 x 3 square, etc. Record the total number of cubes added to make each new square, perimeter, and total squares. Have students look for patterns and record them on a chart. (For example, students may describe patterns they see in the “growing squares,” such as the fact that new squares add change in a predictable way–it increases by the next odd number with each new square.) Extensions: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. Assessment Plan: Journal: Have students explain what square numbers are. Use pictures, words and numbers to explain what 52 is.Author:Utah LessonPlans Created Date :Aug 29 2003 08:53 AM
