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.
Dividing Whole Numbers, Part 2: Division and Partial Quotients
This clip revisits the notion that there are two ways to look at division: as the opposite of multiplication or as repeated subtraction. The clip then introduces partial quotients and explains how they can be used in the subtraction process.
Dividing Whole Numbers, Part 2: Plain Arithmetic Problem, A
This clip presents a basic arithmetic problem which is solved through the use of "educated guesses" and partial quotients.
Dividing Whole Numbers, Part 2: Division Shortcut, A
This clip explains that, "
if you are dividing by a number less than 10, you may have learned to do all the work in your head." It then demonstrates the steps that one would go through in dividing 208 by 8.
Dividing Whole Numbers, Part 2: Practical Problem About Eggs, A
This clip presents a division problem which is solved through the ability to work with multiples of ten, which simplifies the problem, as well as an understanding of partial quotients.
Dividing Whole Numbers, Part 1: Rules of Division
This clip explains 4 rules of division, including never dividing by zero; zero divided by a non-zero number equals zero; any number divided by one equals that number; and, any non-zero number divided by itself equals 1.
Dividing Whole Numbers, Part 1: Remainders
This clip explains when remainders are used, noting that they are unnecessary once fractions are learned.
Fluid Volume: Practical Problems: Converting Between Metric and U.S. Customary Systems
This clip provides practical problems that are solved by converting between metric and U.S. units. The problems include figuring out a hospital's requirements for antiseptic solution, the capacity of an automobile's gas tank, the amount of cough syr...
