Fraction: A symbol that names a component of a entirety, a part of a collection, or location on number line. Example: 1/2, 2/3
Numerator: The number over the fractivity bar in a fraction; it tells just how many type of equal parts.
You are watching: Another name for a fraction bar
Denominator: The number below the fraction bar in a fraction; it tells the full variety of equal parts.
Fraction Bar: The symbol offered to separate the numerator and also denominator.
Fractional Unit: The name of the total number of equal components (halves, thirds, eighths,etc)
Unit Fraction: A fraction with a numerator of 1. example: 1/2, 1/4, 1/8
Benchmark Fractions: Commjust offered fractions such as 1/4, 1/3, 1/2, 2/3, 3/4
|One- half||1/2||One of Two equal parts of a whole|
|One-third||1/3||One ofThree equal parts of a whole|
|One-fourth||1/4||One ofFour equal components of a whole|
|One-fifth||1/5||One ofFive equal parts of a whole|
|One-sixth||1/6||One ofSix equal parts of a whole|
|One-eighth||1/8||One ofEight equal components of a whole|
|One-tenth||1/10||One ofTen equal parts of a whole|
|One-twelfth||1/12||One ofTwelve equal components of a whole|
Mixed Number: A number through a entirety number component and a portion part
Equivalent Fraction: Fractions that name the exact same number
Simplest Form: A fraction through a numerator and also denominator that cannot be divided by the very same divisor, other than 1.
In initially grade and second grades, students comment on partitioning and equal shares. Students will have actually partitioned circles and also rectangles into two, three, and also four equal shares. This is the first time students are understanding/representing fractions via the usage of a number line, and developing deep knowledge of fractional components, sizes, and relationships in between fractions. This is a foundational structure block of fractions, which will certainly be extended in future qualities. Students should have actually ample experiences utilizing the words, halves, thirds, fourths, and also quarters,and the phrases half of, 3rd of, fourth of, and quarter of. Students must additionally job-related through the principle of the entirety, which is created of 2 halves, four fourths or four quarters, and so on.
By the conclusion of this unit, students should be able to show the adhering to competencies:● Identify and give multiple representations for the fractional parts of a entirety (location model), number line, or of a collection, utilizing halves, thirds, fourths, sixths, and eighths.● Recognize and reexisting that the denominator determines the variety of equally sized pieces that comprise a entirety.● Recognize and also reexisting that the numerator determines just how many kind of pieces of the entirety are being referred to in the fraction.● Reexisting and compare fractions through denominators of 2, 3, 4, 6, and also 8, using concrete and photographic models.

MCC3.NF.1 Understand a fraction 1/b as the quantity created by 1 part when a totality is partitioned into b equal parts; understand a fraction a/b as the amount created by a parts of dimension 1/b.
MCC3.NF.2 Understand also a fraction as a number on the number line; reexisting fractions on a number line diagram.a. Reexisting a portion 1/b on a number line diagram by defining the interval from 0 to 1 as the entirety and partitioning it right into b equal parts. Recognize that each part has actually dimension 1/b and that the endallude of the part based at 0 locates the number 1/b on the number line.b. Recurrent a fraction a/b on a number line diagram by noting off a lengths 1/b from 0. Recognize that the resulting interval has actually dimension a/b and also that its endallude locates the number a/b on the number line.
MCC3.NF.3 Exordinary equivalence of fractions in distinct instances, and also compare fractions by thinking around their dimension.a. Understand also two fractions as identical (equal) if they are the very same size or the exact same allude on a number line.b. Recognize and also geneprice easy identical fractions, e.g., 1/2 = 2/4, 4/6 = 2/3). Exsimple why the fractions are indistinguishable, e.g., by utilizing a visual fraction design.c. Express whole numbers as fractions, and also identify fractions that are tantamount to whole numbers. Examples: Expush 3 in the develop 3 = 3/1; acknowledge that 6/1 = 6; situate 4/4 and also 1 at the same suggest of a number line diagram.d. Compare 2 fractions via the very same numerator or the exact same denominator by thinking about their size. Recognize that comparisons are valid just as soon as the 2 fractions describe the exact same totality. Record the results of comparisons through the signs >, =, or MCC3.MD.3 Draw a scaled photo graph and a scaled bar graph to represent a documents collection via a number of categories. Solve one- and two-step “just how many kind of more” and “just how many type of less” problemsutilizing indevelopment presented in scaled bar graphs. For example, attract a bar graph in which each square in the bar graph can represent 5 pets.
MCC3.MD.4 Geneprice measurement information by measuring lengths using rulers marked through halves and fourths of an inch. Show the information by making a line plot, wright here the horizontal scale is marked off in proper units— entirety numbers, halves, or quarters.
Whenever you check out a portion, it have to make feeling. You must think around what the fractivity suggests. In the fractivity 5/6 , the "6" indicates divide somepoint right into 6 equal components, and the "5" suggests 5 of these parts. The fractivity 5/6 represents practically the whole of something because it represents 5 out of 6 equal parts. As viewed below:

This fractivity bar mirrors 4/4 filled:
In situation you require additional help, you have the right to watch this youtube video around fraction bars.
We will call a full circle aunit. Thisunitis split into 3 equal components. If we take the 2 colored parts, we have actually taken 2 of the three equal components.
The top number 2 in the numeral 2/3is the numerator. The numerator tells us exactly how many kind of of the parts in the unit are to be taken.
The bottom number 3 in the numeral 2/3is the denominator. The denominator tells us the full number of equal components right into which the unit is separated. In this example tright here are 3 equal components in the circle.
The line in between the numerator and also denominator is known as thefraction bar. It is likewise dubbed thedepartment bar.
You will certainly enter the fraction 2/3bereason 2 of the 3 parts in the circle are colored.
Label each number line with the correct fractions the tick marks reexisting. “First, let’s count the full variety of equal components from zero to one. This will be our denominator. Next off, let’s label each component in in between zero and one as a fraction via the denominator we determined above.”
Example: Find 9/12 on a number line.
1. Make 12 equal parts between 0 and also 1 considering that 4/12 is less than one entirety.

2. Label each tick mark.
3. Put dot on provided number (4/12)
You can additionally use a bar version to assist settle and attract out equal parts.Due to the fact that there is twelve components total, the denominator will certainly be twelve. Each component of the bar version is 1/12
