Common Denominators Center 1
Common Denominators Center
In this center activity students students use ordinary playing cards to review finding common denominators. This helps them develop fluency and flexibility with fractions operations.
Students draw playing cards to create two fractions and then find the common denominator.The number of “”problems”” they can do this is only limited by time!
Engage students in this center while you pull other students for intervention or tutoring.
This activity includes clear and concise teacher and student directions for independent center work, and conversation starters that give students what they need to have meaningful academic discussions.

Explain why a fraction a/b is equivalent to a fraction (n ร a)/(n ร b) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to ...
- CCSS.MATH.CONTENT.5.NF.A.1
Add and subtract fractions with unlike denominators (including mixed numbers) by replacing given fractions with equivalent fractions in such a way as to produce an equivalent sum or difference of fractions with like denominators. For example, 2/3 + 5...
