Number Patterns
Mathematics
Grade Level Expectations: Third Grade
► Patterns, Relations, And Functions - In problemsolving investigations, students demonstrate an
understanding of patterns, relations, and functions
that represent and explain real-world situations.
47. Find patterns to complete tables, state the rule
governing the shift between successive terms, and
continue the pattern (including growing patterns)

Big Idea
Patterns are used in everyday life. An
understanding of patterns enables
problem-solving success in a number of
situations involving predictions. For
example, weather predictions are based
on patterns.
Guiding Questions:
•
•
•
What is the rule governing shifts between
successive terms?
How would you continue number
patterns?
Can you use number patterns to
complete a T-Chart?

Number Patterns
First, let’s practice the rules!

Rule:
Subtract

Number Patterns
How do I recognize
the pattern?
• First, look at the numbers next to each
other.
• Next, ask, “What am I doing to the 1st
number to get the next number? This is
the RULE of the pattern.
• Finally, continue the pattern using the
rule.

Solve the word problem using what
you learned about Number Patterns.
Make a T-Chart on the back of your
Checklist. Complete the chart to solve
the problem.
Do this first, and then check your work
with the answer on the next slide.
Solve:
We planted a seed & took care of it every
day. At the end of week 1, the plant was 2
inches tall. At the end of week 2, it was 4
inches. At the end of week 3, it was 6
inches tall. If this trend continues, how tall
will it probably be at the end of week 7?
