Algebra
Topic:
Students will use pattern blocks to develop an understanding of algebraic generalization(pattern) in order to write a mathematical equation using algebraic symbols. Teacher will provide experiences from the concrete to the symbolic reasoning

Lesson Created by:
Diane DeNoon and Diane Richards, Theodore Roosevelt Elementary, Manhattan,KS
Lesson Description:
Materials
 BookEach Orange Has 8 Slices by Paul Giganti, Pattern blocks, overhead of problem from "Building Algebraic Thinking with Progressive Patterns" by Bob Willcutt, Critical Thinking Press
1. Launching the Lesson
 Give a pretest to each student
 In a learning team the students will complete worksheet one
 Whole class instruction build a design with pattern blocks on an overhead. Discuss vocabulary such as generalization, variable, pattern, mathematical equations, and etc.
2. Developing the Lesson
 Students will build designs using pattern blocks.
 Teacher will question the students. For example, Did you notice the pattern developing? How is the pattern growing? How many blocks will you need for the 18, 224,...design? How will you find n?
 The students will fill out a Tchart to record their design and blocks.
 The students will use the "Thinksharewrite strategy to communicate their thinking on a worksheet.
1. Closure
 Each student will get a copy of a page from the book Each Orange Has 8 Slices by Paul Giganti.
 The students will complete a Tchart based on the pattern from the book page and complete a Thinksharewrite strategy with a partner to communicate their algebraic thinking.
 The students will write an algebraic expression that describes their pattern.
 Extension Each student will make their own page to a book
 Post test the students
