# Math (TAG): Fraction Equivalence, Comparison, and Addition and Subtraction with Like and Unlike Denominators

### Suggested Time Frame: 14 Instructional Days

##### Focus TEKS

Representing Fractions (Including Improper Fractions and Mixed Numbers)

• 4.3A  represent a fraction a/b as a sum of fractions 1/b, where a and b are whole numbers and b > 0, including when a > b S
• 4.3B  decompose a fraction in more than one way into a sum of fractions with the same denominator using concrete and pictorial models and recording results with symbolic representations S
• 4.3G Represent fractions and decimals to the tenths or hundredths as distances from zero on a number line S

Equivalent Fractions

• 4.3C  determine if two given fractions are equivalent using a variety of methods S

Comparing Fractions with Like and Unlike Denominators

• 4.3D Compare two fractions with different numerators and different denominators and represent the comparison using the symbols >, =, or < R

Add and Subtract Fractions with Like and Unlike Denominators

• 5.3K Add and subtract positive rational numbers fluently- R
• 5.3A Estimate to determine solutions to mathematical and real-world problems involving addition, subtraction, multiplication, or division – S  [addition and subtraction in this unit]
• 5.3H Represent and solve addition and subtraction of fractions with unequal denominators referring to the same whole using objects and pictorial models and properties of operations- S
##### Computational Fluency TEKS

Relate Fractions and Decimals

• 4.2G relate decimals to fractions that name tenths and hundredths; – R RC1
• 4.2H determine the corresponding decimal to the tenths or hundredths place of a specified point on a number line. – S RC1
##### Spiral Review TEKS

Algebraic Reasoning

• 5.4B represent and solve multi-step problems involving the four operations with whole numbers using equations with a letter standing for the unknown quantity R
• 5.4C generate a numerical pattern when given a rule in the form y = ax or y = x + a and graph R
• 5.4D recognize the difference between additive and multiplicative numerical patterns given in a table or graph S
• 5.4E describe the meaning of parentheses and brackets in a numeric expression S
• 5.4F simplify numerical expressions that do not involve exponents, including up to two levels of grouping R
• 5.4A  Identify prime and composite numbers- S
