Chapter 3


Chapter 3 is a very important chapter as mastery of addition and subtraction of fractions is a CCSS big idea for grade 5. Use visual models to represent fractions. This chapter expects that students can find common denominators if students struggle with understanding equivalent fractions go back to grade 4 materials and use paper strips or fraction circles. Be sure to locate fractions on the number line and operations should be modeled there too. CCSS emphasizes this model for fractions. Fact Fluency – 5 minutes 3x a week.
