Dividing Whole Numbers, Part 1: Division's Relationship to Multiplication and Subtraction, Part Two
This clip continues the previous discussion about viewing division as a shortcut for repeated subtraction or as the opposite of multiplication.
Dividing Whole Numbers, Part 1: Division's Relationship to Multiplication and Subtraction, Part One
This clip explains that division is a shortcut for repeated subtraction, and is also the opposite of multiplication.
Dividing Whole Numbers, Part 1: Division Facts
This clip explains that it's not necessary to write out all the division facts, because "
we can get them by working backward from the multiplication table."
Dividing Whole Numbers, Part 1: Few Division Problems, A
This clip offers two practical division problems which can be solved using techniques taught previously, including repeated subtraction and multiplication.
Dividing Whole Numbers, Part 1: Defining Dividend, Divisor and Quotient
This clip defines the three components that make up a division problem: the dividend, divisor, and quotient.
Dividing Whole Numbers, Part 2: Summary: Dividing Whole Numbers, Part Two
This clip summarizes the key points in Part 2 of Dividing Whole Numbers, including the concepts of repeated subtraction and partial quotients. The clip also refers to long division, stating that what we've learned in this lesson is very much like lo...
Dividing Whole Numbers, Part 2: Problem Involving Bottles of Soda, A
This clip presents a division problem which is solved with the use of partial quotients, and whose answer is checked through multiplication.
Dividing Whole Numbers, Part 1: Summary: Dividing Whole Numbers, Part One
This clip summarizes the key points in Part 1 of Dividing Whole Numbers, including the introduction of the terms dividend, divisor and quotient. It then explains that division was introduced in two different ways: as a shortcut for repeated subtract...
Dividing Whole Numbers, Part 2: Partial Quotients and Multiples of Ten
This clip explains how understanding and learning powers of ten and learning multiples of ten can reduce the number of partial quotients needed to solve a division problem.
Dividing Whole Numbers, Part 2: Comparing Methods of Division
This clip explains that dividing can sometimes be done more quickly for those comfortable with guessing the partial quotient rather than figuring it out. On the other hand, the method known as "long division" offers another approach altogether.
