Standards and Learning Objectives

- Grade 3 -- Chapter 9: Fractions
- Students will focus on understanding, writing, and comparing fractions and mixed numbers.
- 3rd Grade Standards:
- 3N3 Identify and represent fractions (between 0 and 1 with denominators through 10) as parts of unit wholes and parts of groups.
- Model and represent a mixed number (with denominator 2, 3, or 4) as a whole number and a fraction, e.g., 1 2/3, 3 ½.
- 3N4 Locate on the number line and compare fractions (between 0 and 1 with denominators 2,3, or4, e.g., 2/3).
- 3N8 Select and use appropriate operations (addition, subtraction, multiplication, and division to solve problems, including money).
- 3N13 Use concrete objects and visual models to add and subtract (only when the answer is greater than or equal to zero) common
- fractions (halves, thirds, fourths, sixths, and eighths) with like denominators.
- Chapter 9 Learning Objectives:
- 9-1: Identify regions that have been divided into equal-sized parts, and divide regions into equal-sized parts.
- 9-2: Identify and draw fractional parts of regions.
- 9-3: Find equivalent fractions using models such as fraction strips.
- 9-4: Compare and order fractions.
- 9-5: Estimate fractional parts of regions.
- 9-6: Identify and locate fractions on a number line.
- 9-7: Identify fractional parts of sets or groups and divide sets to show fractional parts.
- 9-8: Find the number of objects in a fractional part of a set where the numerator is 1.
