Fractions are used to represent parts of whole numbers . Fractions always have a top and a bottom number. The number at the bottom . (denominator. ) tells you the size of the parts that make the . whole, e.g. . What is half of 545?. 1/2 of 500 = 250. 1/2 of 5 = 2. ½. . So half of 545 must be 272. ½. or 272.5. 1/2 of 40 = 20.

Learning Target:. Students will be able to divide fractions by other fractions, mixed numbers, and whole numbers.. Apply . and extend previous understandings of multiplication and division to divide fractions by fractions.. Percents. . Go Together…Like PB & J!. Charline. Brown. How do our kids view fractions?. Most students see parts-to-whole relationships only.. Explain the numerator as “number you have” and the denominator as “number you have in all”?. Standard 2.G.3. To be a fraction, . a shape must . have . EQUAL parts. Equal parts means that all parts are the same size. Do these shapes show equal parts? Why do you think so?. Equal Parts .

Students express fractions as fair sharing, parts of a whole, and parts of a set. They use various context (candy bars, fruit, cakes) and a variety of models (circles, squares, rectangles, fraction bars, and number lines) to develop understanding of fractions and represent fractions. with Models.
