Multiplication and Division

Parent Information

Our Focus

We are beginning to work on our multiplication and division unit. In this unit students will learn how to multiply two digit by two digit numbers and do long division with up to a 4 digit number by a 1 digit number. Students will be using this information to solve real world problems involving multiplication and division.


Instructional Approach

This year in 4th grade students will use both alternative methods and the standard algorithms to multiply and divide. The alternative methods are called partial product and partial quotient. These methods are taught so that students understand how place value works with multiplication and division. After students understand the role of place value in multiplication and division they will learn the standard algorithms for multiplication and division. Students will use real world problem solving situations to apply multiplication and division in meaningful ways. Students will understand that multiplication occurs when equal groups are joined. Division occurs when equal amounts are made into groups. All of these skills will be used to help our 4th grade mathematicians evaluate problems, plan, solve, represent and justify their thinking.
