New Math TEKS Grades 3-5 Involving Fractions and Decimals. 5.3 (J)represent . division of a unit fraction by a whole number and the division of a whole number by a unit fraction such as 1/3 ÷ 7 and 7 ÷ 1/3 using objects and pictorial models, including area models. 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. . A standard track is . mile long. If I ran 3 laps around the track how far did I run? .  . How can you represent and locate fractions on a number line?. A standard track is . mile long. If I ran 3 laps around the track how far did I run? . MAFS.3.NF.1.3c. Lesson Opening.

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.
