Fractions Overview: Lessons One through Eight
Lesson 1: Subunit Intervals. By the end of the lesson, students will use units and subunits to identify and match fractions in area model and number line representations.
Lesson 2: Defining Denominator, Numerator, and Fractions. By the end of the lesson, students will be able to create C-rod models of unit-subunit relationships, name the subunits (e.g., “fourths”), and use the definitions of denominator and numerator to label fractions on the line.
Lesson 3: Labeling Fractions and Understanding Lengths of Subunits. By the end of the lesson, students will use the definitions of denominator and numerator to label fractions on the line and reason about the relationship between the length of the subunit and the value of the denominator.
Lesson 4: Less than 1 - Measuring Lengths. By the end of the lesson, students will be able to apply the principles of subunit, numerator, and denominator to mark fractions less than 1 on the line.
Lesson 5: Reasoning about Fractions Less than 1. By the end of the lesson, students will be able to apply the principles of subunit, numerator, and denominator to reason about fractions less than 1 and mark them on a number line.
Lesson 6: Measuring Distances Less than 1. By the end of the lesson, students will apply the definitions of subunit, denominator, and numerator to measure distances from 0 on the number line and label the distances as fractions less than 1.
Lesson 7: Mixed Numbers. By the end of the lesson, students will apply the definitions for multiunit, unit, and subunit to place fractions greater than 1 on the number line and label these points as mixed numbers.
Lesson 8: Fractions Greater than 1. By the end of the lesson, students will be able to label whole numbers as fractions (e.g., 2 and 8/4) and label points greater than 1 and between whole numbers as both mixed numbers and as fractions with the denominator greater than the numerator (e.g., 1 1/4 and 5/4).
