PS 309 Grade 5 Chapter 2 Curriculum Map
Chapter Title: Divide Whole Numbers
Time Frame: September/October (3 weeks)
Grade Level and Subject: Grade 5 Mathematics
Big Ideas/ Enduring Understandings:
Extending division to 2-digit divisors, integrating decimal fractions into the place value system and
developing understanding of operations with decimals to hundredths, and developing fluency with whole
number and decimal operations.
 Number and Operations in Base Ten
 Number and Operations - Fractions
Common Core Standards (see Go Math Chapter 2 for CCLS)
5NBT.6 Find whole-number quotients of whole numbers with up to four-digit dividends and two-digit divisors, using strategies based on
place value, the properties of operations, and/or the relationship between multiplication and division. Illustrate and explain the calculation
by using equations, rectangular arrays, and/or area models.
5.NF.3 Interpret a fraction as division of the numerator by the denominator (a/b = a ÷ b). Solve word problems involving division of
whole numbers leading to answers in the form of fractions or mixed numbers, e.g., by using visual fraction models or equations to
represent the problem. For example, interpret 3/4 as the result of dividing 3 by 4, noting that 3/4 multiplied by 4 equals 3, and that when
3 wholes are shared equally among 4 people each person has a share of size 3/4. If 9 people want to share a 50-pound sack of rice equally
by weight, how many pounds of rice should each person get? Between what two whole numbers does your answer lie?

Go Math!: September/October 2015 (15 days)
*Select lessons from Grade 5 chapters 1 and 2 depending on student mastery of grade 4 standards based on
the Prerequisite Skills Inventory. There are 21 total lessons in Chapter 1 and 2 of Grade 5, and 14 days in
September to review multiplication and division of whole numbers from these units as well as to review
fractional concepts from grade 4 (mentioned above). Based on the data from the Prerequisite Skills
Inventory select which lessons to use with which students, for added RTI support and grouping.
*For remedial groups and enrichment see RTI/Reteach and Enrichment Guides for 5th grade chapter 2.
**Use the Chapter Pre-Test and Post-Tests as additional assessment if necessary.
