Unit 3: Fractions
Section 8: Representing, Comparing and Equivalence for fractions
- represent fractions using area, length, number line and discrete
- understand and compare sizes of fractions by relating them to
unit fractions and benchmark numbers
- write word problems for fraction addition
- add fractions with like and unlike denominators using
manipulatives and diagrams
- know what a prime number is, and why 1 is not prime
- understand factors and multiples, and find least common multiples
and greatest common factors using lists and prime factorizations.
Fraction models and representations
Different models for fractions (ways to
approach the idea of fraction. Note: we are going to emphasize the repeated units model in this unit, which relies on the part-whole model)
