When dividing by greater and greater powers of 10, the digits move to lesser and lesser place-value positions. When using the standard algorithm for multiplying decimals, students may determine the number of decimal places in the answer by counting the decimal places to the left of the decimal point instead of the right.
If students have used the number line to model fraction multiplication, they will have the experience necessary to connect the number line model of division of fractions back to the number line model of multiplication of fractions.
When using rectangular area models, the same result may look different. It is called a factor because you can multiply it by the quotient to get the larger number. Today, I ask students to trade their journals with another person, but to not talk about them.
How many pounds of peanuts should you put into each bag? Students who struggle to position the decimal point correctly when multiplying decimals may benefit from writing the decimals as fractions first, and then multiplying.
Of these steps, 2 and 3 can become difficult and confusing to students because they don't seemingly have to do with division—they have to do with finding the remainder. What's a common denominator? Just as with subtraction, order matters; division is not commutative.

Divide the divisor in this case, 5 into the left digit or digits of the dividend in this case, Why is the ability to model quantitative relationships in a variety of ways essential to solving problems in everyday life?
These contextual situations provided real life experiences for students to construct multiplication models concrete, pictorial, and areaequal groups, arrays, strip diagrams, and equations in relevant ways.
Half of them draw circles. What patterns exist within different types of quantitative relationships and where are they found in everyday life? They are told to pretend that one of them is the teacher, and the other partner pretends they are a 2nd grade student who knows nothing at all about division.Search the history of over billion web pages on the Internet.
