Fraction: A symbol the names a part of a whole, a component of a set, or ar on number line. Example: 1/2, 2/3

Numerator: The number above the fraction bar in a fraction; it speak how countless equal parts.

You are watching: Another name for a fraction bar

Denominator: The number listed below the portion bar in a fraction; it tells the total variety of equal parts.

Fraction Bar: The symbol used to separate the numerator and also denominator.

Fractional Unit: The surname of the total variety of equal parts (halves, thirds, eighths,etc)

Unit Fraction: A fraction with a numerator of 1. Example: 1/2, 1/4, 1/8

Benchmark Fractions: frequently used fractions such together 1/4, 1/3, 1/2, 2/3, 3/4

 Words Fraction Definition One- half 1/2 One of 2 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 parts of a whole One-tenth 1/10 One often equal parts of a whole One-twelfth 1/12 One ofTwelve equal parts of a whole

Mixed Number: A number with a totality number part and a portion part

Equivalent Fraction: Fractions that name the same number

Simplest Form: A fraction with a numerator and also denominator that cannot be separated by the same divisor, except 1.

In very first grade and 2nd grades, students discuss partitioning and also equal shares. Students will have partitioned circles and also rectangles into two, three, and four same shares. This is the first time students space understanding/representing fractions through the usage of a number line, and developing deep understanding of spring parts, sizes, and also relationships between fractions. This is a foundational structure block that fractions, which will certainly be expanded in future grades. Student should have ample experiences using the words, halves, thirds, fourths, and quarters,and the phrases half of, third of, fourth of, and quarter of. Students should also work v the idea that the whole, i m sorry is created of 2 halves, 4 fourths or 4 quarters, etc.

By the conclusion that this unit, students should have the ability to demonstrate the adhering to competencies:● Identify and also give multiple representations for the fractional parts of a whole (area model), number line, or that a set, using halves, thirds, fourths, sixths, and eighths.● Recognize and represent that the denominator identify the variety of equally sized piece that comprise a whole.● Recognize and also represent that the numerator determines how countless pieces that the whole are being described in the fraction.● Represent and compare fractions with denominators that 2, 3, 4, 6, and also 8, using concrete and pictorial models.

MCC3.NF.1 Understand a portion 1/b together the quantity formed by 1 component when a totality is partitioned into b equal parts; know a portion a/b as the quantity formed by a components of size 1/b.

MCC3.NF.2 Understand a fraction as a number ~ above the number line; stand for fractions on a number heat diagram.a. Represent a fraction 1/b on a number line diagram by specifying the interval native 0 come 1 together the whole and also partitioning it right into b equal parts. Identify that each part has size 1/b and that the endpoint the the component based at 0 locates the number 1/b top top the number line.b. Represent a fraction a/b top top a number heat diagram by noting off a lengths 1/b native 0. Recognize that the result interval has size a/b and that the endpoint locates the number a/b on the number line.

MCC3.NF.3 describe equivalence of fountain in distinct cases, and also compare fountain by reasoning about their size.a. Recognize two fractions as indistinguishable (equal) if they space the same size or the same suggest on a number line.b. Recognize and also generate an easy equivalent fractions, e.g., 1/2 = 2/4, 4/6 = 2/3). Define why the fractions space equivalent, e.g., by using a visual fraction model.c. Express entirety numbers together fractions, and also recognize fractions the are tantamount to entirety numbers. Examples: refer 3 in the type 3 = 3/1; recognize that 6/1 = 6; find 4/4 and 1 at the same suggest of a number line diagram.d. Compare two fractions with the same numerator or the exact same denominator through reasoning about their size. Identify that comparisons room valid only as soon as the two fractions describe the same whole. Record the outcomes of comparisons with the icons >, =, or MCC3.MD.3 attract a scaled photo graph and a scaled bar graph to stand for a data collection with number of categories. Deal with one- and also two-step “how numerous more” and also “how plenty of less” problemsusing details presented in scaled bar graphs. For example, draw a bar graph in which every square in the bar graph can represent 5 pets.

MCC3.MD.4 generate measurement data by measuring lengths making use of rulers marked with halves and also fourths of one inch. Show the data by make a heat plot, where the horizontal scale is marked off in proper units— entirety numbers, halves, or quarters.

Whenever you check out a fraction, it need to make sense. You have to think about what the portion means. In the portion 5/6 , the "6" way divide something into 6 same parts, and the "5" shows 5 of this parts. The fraction 5/6 represents almost the totality of something since it represents 5 out of 6 equal parts. As checked out below:

 X X X X X

This portion bar mirrors 4/4 filled:

We will speak to a full circle aunit. Thisunitis separated into 3 same parts. If us take the two colored parts, we have actually taken 2 of the three equal parts.

The optimal number 2 in the character 2/3is the numerator. The numerator tells united state how plenty of of the parts in the unit space to be taken.

The bottom number 3 in the character 2/3is the denominator. The denominator tells us the total variety of equal parts into which the unit is divided. In this instance there are 3 equal components in the circle.

The line in between the numerator and also denominator is well-known as thefraction bar. That is also called thedivision bar.

You will enter the fraction 2/3because 2 the the 3 parts in the circle space colored.

Label each number line with the exactly fractions the mite marks represent. “First, let’s counting the total variety of equal parts from zero to one. This will certainly be our denominator. Next, let’s brand each component in between zero and also one as a portion with the denominator we determined above.”

Example: uncover 9/12 top top a number line.

1. Do 12 equal parts in between 0 and 1 because 4/12 is much less than one whole.

2. Brand each tick mark.

3. Placed dot on offered number (4/12)

You can likewise use a bar design to help solve and also draw out equal parts.Since over there is twelve components total, the denominator will certainly be twelve. Each component of the bar version is 1/12
