Division Models for Whole Numbers and Integers
Transcript of Division Models for Whole Numbers and Integers
There are three different ways you can write a division problem.
30 3 =
3 30 The Sharing Approach If we have 3 people and we want to distribute 30 balls between them we will use the sharing approach by distributing the balls between the students evenly. 10
3 30 The Measurement Approach If we have 30 balls and we want to give 3 balls to an undetermined number of groups, we will discover that 3 balls will be distributed to 10 groups. 30 3 = 10 The Missing Factor Approach Since division is an inverse operation of multiplication we can find missing factors by using multiplication. ______ 3 = 10 ______ 3 = 10 30 http://ma-gb-en-pr.whizz.com.s3.amazonaws.com/flash/ex/MA_GBR_0700KAx0200.swf Games & Quizzes References = 8.
