Multiply and Divide Whole Numbers Unit

The Multiplying and Dividing Whole Numbers Unit involves using patterns and place value to develop strategies to multiply and divide whole numbers. Questions to answer may include:

• How are models useful for representing the processes of multiplication and division? (Models might include equal jumps on a number line, arrays/area models, or base ten materials.)
   
• How are the properties of place value (additive, multiplicative, base-ten & positional) useful in developing efficient procedures for multiplying and dividing whole numbers?
   
• How can mental math, rounding, and/or the use of compatible numbers help to determine whether the solution to a multiplication or division problem is reasonable?

4.OA.A.3

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.
