Chapter 7
          In Second Grade, students were introduced to the idea of fractions.  They learned to partition shapes into two, three, or four equal parts, and describe the parts using halves, thirds, or fourths.  Fractions were represented using models that helped students to visulaize the relationship between the parts and the wholebefore moving on to the more abstract symbolic level in Grade 3.
          In this chapter, students will work with fractions of wholes that are divided into more than four equal parts: sixths and eighths.  Students will learn new concepts such as equivalent fractions and identifying a fraction of a set using their understanding of unit fractions.  Students will develop an understanding of the different meanings and uses of fractions, such as representing parts of a whole, parts of a set, points or distances on a number line, and more than one whole represented as a fraction.
         Students are introduced to each fraction concept using concrete materials like fraction bars, fraction circles, and connecting cubes.  Pictorial representations are then used to help students to understand the concepts of fractions.  Bar models and number lines are both used to represent fractions so students can find equivalent fractions, and compare fractions to find the lesser or the greater fractions.
