Strategies for Division
Common Core State Standards:
4.NBT.6 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.
· inverse operation
· area model
· expanded notation
· algebraic notation
In this unit, students will apply their understanding of place value to help them explore multiple groups or division. Students will utilize their knowledge of base ten and groups of numbers within another number to help them solve for multi-digit division. This will be the students’ first exposure to remainders. Students will be asked to reason with remainders and make connections to prime and composite numbers. Students will solve multi-digit division problems with the use of various strategies listed below. Students will not be required to use the standard algorithm until 5th grade.
Students will build on their understanding of addition and subtraction by using place value strategies to make sense of the standard algorithms. They are expected to use a variety of models to support their reasoning about numbers.
· Rectangular Section/Arrays
· Base Ten blocks
· Expanded notation
· Algebraic notation
