-Determine the greatest common factor among 2 numbers less than 100.

A complete set of 40 task cards that correlate to:

CCSS: 6.NS.B Compute fluently with multi-digit numbers and find common factors and multiples.

CCSS:6.NS.B.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 two whole numbers with no common factor.

These cards provide excellent practice for 6th grade students, as well as a great review for 7th grade math and enhancement for 4th and 5th grade students. They are a great way to check the understanding and mastery of the skills!

Student response sheet and teacher answer key included!

• 40 Task Cards for classroom use after the concept has been taught.
• Gives students extra practice in order to enhance mastery of the skill.

Ideas for use in the classroom:

• Whole group challenge by having students respond to each task card on individual dry erase boards.
• Whole group “Scoot” activity: Give students a specified amount of time to complete the card in front of them. Set timer. When timer sounds, each student moves to another seat to complete a new card. Continue until all cards have been completed by all students. *This may be fun for the students, but it will give the teacher a better idea as to how many students have mastered the skill well enough to complete the tasks correctly in a specified amount of time.
• Small group use in centers
• Individual practice for students when they have finished their classwork early.

These are especially handy when single hole punched in a corner and stored on a book ring! I put mine in sets of 10 so students can quickly finish a set when they have a few minutes after a test or after finishing an assignment.

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 two whole numbers with no common factor. For example, express 36 + 8 as 4 (9 + 2).
Find all factor pairs for a whole number in the range 1-100. Recognize that a whole number is a multiple of each of its factors. Determine whether a given whole number in the range 1-100 is a multiple of a given one-digit number. Determine whether a given whole number in the range 1-100 is prime or composite.
