Patterns in the Common Core:

Read about the 4th grade Common Core Math Standard 4.OA.5 in this flipbook of information about the grade 4 standards: http://katm.org/wp/wp-content/uploads/flipbooks/4FlipBookedited.pdf (the standard starts on page 17 of the pdf file).

Answer the following questions from the flipbook information:

1. How are patterns and rules related?

2. What is an example of a growing number pattern?

3. What is an example of a growing shape pattern?

4. What does it mean to undo a pattern? Gove an example.

5. Draw out the rectangle growing pattern that is provided in the flip book. The flipbook suggests that multiplying by 3 is a corresponding numerical pattern. Draw out the next rectangle, and find the numbers of squares in each rectangle. Does multiplying by 3 each time seem like a good way to describe the pattern? Why or why not?

The flip book suggests these two web sites for sample lessons to look at:

Snake patterns: http://www-tc.pbs.org/teachers/mathline/lessonplans/pdf/atmp/SnakePatterns.pdf

Illuminations patterns that grow: http://illuminations.nctm.org/LessonDetail.aspx?id=U103

6. Choose one of the above lessons to read. Which aspects of growing patterns are involved in the lesson? (shapes? numbers? finding a rule? working backwards?)
