Unit Title: Prime Time
Suggested Time: Unit does not begin until day 8. Unit will take approximately 14 days.
Enduring understanding (Big Idea): 1. Determining the factors of whole numbers. 2. Finding greatest common factors and generating multiples. 3. Determining prime
factorization. 4. Classifying numbers as prime or composite. (FOUND IN TEACHER’S EDITION ON MATHEMATICAL HIGHLIGHTS PAGE)
Essential Questions: Will breaking a number into factors help me solve the problem? What relationships will doing that help me see? What do the factors and multiples of the
numbers tell me about the situation? How can I find the factors of the numbers? How can I find the multiples? What common factors and common multiples do the numbers have?

Common Core Standards
Alignment/Mathematical Practices
Connection to 2003 Standards
6.EE.2.b Identify parts of an expression using
mathematical terms (sum, term, product, factor,
quotient, coefficient); view one or more parts of
an expression as a single entity. For example,
describe the expression 2(8 + 7) as a product of
two factors; view (8 + 7) as both a single entity
and a sum of two terms described verbally
1.05 Develop fluency in the use of
factors, multiples, exponential
notation, and prime factorization.
Mathematical Practices:
3. Construct viable arguments and critique the
reasoning of others.
5. Use appropriate tools strategically.

Math Reflections
7. Look for and make use of structure.
6.NS.4 Find the greatest common factor of two
whole numbers less than or equal to 100 and the
least common multiple of two whole numbers less
than or equal to 12. Use the distributive property
to express a sum of two whole numbers 1–100
with a common factor as a multiple of a sum of

example, express 36 + 8 as 4(9 + 2.
Mathematical Practices:
1. Make sense of problems and persevere in
solving them.
4. Model with Mathematics.
5. Use appropriate tools strategically.
