Decimal and Percent Concepts and Decimal Computation
This activity contains 10 questions.
When connecting fractions to decimals, we should
Use models to explore the families in rational numbers
Extend the base-ten decimal system to numbers less than one
Use the symbols of equivalences such as 1.75 and 1¾.
Use operations to show methods of translating between fractions and decimals
Before considering decimal numerals, it is wise to review old concepts. One of the most basic ideas relevant to decimal numerals is
The expanded form translating from fractions to decimals
Whether the fraction it represents is more or less than ½ , 0, or 1
The ten-to-one relationship between the value of two adjacent positions
Decimals are easier to use than fractions
Early work with base-ten fractions is designed primarily to include all of the following EXCEPT....
To extend the place value system for computational issues
To learn to read and write base-ten fractions in different ways
To acquaint students with the models
To help them begin to think of quantities in terms of tenths and hundredths
To model 1/3 as an infinitely repeating decimal, students should first
Utilize the calculator to convert the problem
Looking at a 10 x 10 square to determine what 1/3 would represent
Model 1/3 as a decimal by partitioning the whole square into 3 parts using strips and squares
Attempt to divide the numerator into the denominator and extending infinitely
Most common models for fractions do not depict the decimal equivalence.
The most common length model is a meter stick.
To understand the place value of a decimal such as 0.45, it should be thought of as 4 tenths and 5 hundredths.
Any base 10 model can be a decimal model as well.
According to the NAEP exams, children can easily master fraction-decimals equivalences for mixed numbers.
Explain 2 models for representing the number 0.75.
To create paragraphs in your essay response, type <p> at the beginning of the paragraph, and </p> at the end.
