Before You Begin This Unit...
  Unit at a Glance

The work of this unit builds on the work of units 1 and 3. In unit one students worked to solidify fluency that started in grade 3 unit  5. Before beginning this unit you will want to use data collected in units 1 and 3 to identify and support students who are not meeting 3 grade expectations for fluency. These students will struggle within this unit because this unit assumes students have strategies for  determining the products for the facts that they don’t know automatically. Read the NC-CCS to familiarize yourself with the expectations for each standard that is related to multiplication.

Interpret a multiplication equation as a comparison, e.g., interpret 35 = 5 × 7 as a statement that 35 is 5 times as many as 7 and 7 times as many as 5. Represent verbal statements of multiplicative comparisons as multiplication equations.

Multiply or divide to solve word problems involving multiplicative comparison, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem, distinguishing multiplicative comparison from additive comparison.1

Solve multistep word problems posed with whole numbers and having whole-number answers using the four operations, including problems in which remainders must be interpreted. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding.

Multiply a whole number of up to four digits by a one-digit whole number, and multiply two two-digit numbers, using strategies based on place value and the properties of operations. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.

Find whole-number quotients and remainders with up to four-digit dividends and one-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. 1 Grade 4 expectations in this domain are limited to whole numbers less than or equal to 1,000,000.
