Unit 3: 5.03 On Fraction Concepts, Addition, and Subtraction Unit 3 focuses on understanding, comparing, and solving problems with fractions. This unit develops ideas about:
M5N4. Students will continue to develop thier understanding of the meaning of common fractions and compute with them.
a: Understand division of whole numbers can be represented as a fraction (a/b = a ÷b).
b: Understand the value of a fraction is not changed when both its numerator and denominator are multiplied or divided by the same number
because it is the same as multiplying or dividing by one.
c: Find equivalent fractions and simplify fractions.
e: Explore finding common denominators using concrete, pictorial, and computational models.
f: Use <, >, or = to compare fractions and justify the comparison.
g: Add and subtract common fractions and mixed numbers with unlike denominators.
Online Resources for Students:National Library of Virtual Manipulatives: The National Library of Virtual Manipulatives (NLVM) is an NSF supported project that began in 1999 to develop a library of uniquely interactive, web-based virtual manipulatives or concept tutorials, mostly in the form of Java applets, for mathematics instruction (K-12 emphasis). http://nlvm.usu.edu/en/nav/vlibrary.html
Equivalent Fractions: Create equivalent fractions by dividing and shading squares or circles, and match each fractions to its location on the number line. http://illuminations.nctm.org/Activities.aspx?grade=2&grade=3
NCTM Communicating about Mathematics Using Games, Playing Fraction Track: Interactive game that provides practice with using knowledge about equivalent fractions. http://standards.nctm.org/document/eexamples/chap5/5.1/
Learn NC: List of the recommended lesson plans and websites available to help students learn about and be comfortable with fractions.

Cyberchase, Games Central, Melvin’s. Make A Match: In Melvin's messy lab, players need to find matching potion bottles. The bottles can be matched using the information on their labels-- equivalent fractions. Students can print a worksheet for more practice after completing the game.
