 Math Math 4 Grade 4 OA Operations & Algebraic Thinking C Generate and analyze patterns 5 Generate a number or shape pattern that follows a given rule. Identify apparent features of the pattern that were not explicit in the rule itself. For example, given the rule "Add 3" and the starting number 1, generate terms in the resulting sequence and observe that the terms appear to alternate between odd and even numbers. Explain informally why the numbers will continue to alternate in this way. Download Common Core State Standards (PDF 1.2 MB)
Lesson Objective
Students find the rule that determines the number of chessboard squares
Length
6 min
Questions to Consider
See how Ms. Bottomley uses a function machine to have students predict the rule
How does the lesson help students see the difference between additive and multiplicative patterns?
What about the lesson helps students be successful with this complex pattern?
