# TEKS Math Samples (for Texas)

Yours to try, free: Performance tasks that connect both the TEKS Mathematical Content Standards to the Mathematical Processes. Featuring differentiated instructional tasks and summative assessments with anchor papers, these engaging tasks let every student build their skills through solving real-world DOK 3-level problems.

The samples below are organized by Units of Study around the Math TEKS and include problem-solving performance tasks, teacher planning sheets, rubrics, student anchor papers, and scoring rationales. And, they reflect just a few of the 380+ tasks in Problem Solving for the 21st Century: Built for the TEKS.

## Kindergarten

### Comparing Numbers Unit

#### Comparing Numbers Unit

The Comparing Numbers Unit involves understanding the relative position and magnitude of whole numbers, and their relationships within the numeration system. Students will answer questions such as:

• Which group has more? Less?

• Do any groups have the same number? How do you know?

TEKS standards covered: K.2E, K.2F, K.2G, K.2H

### Strategies for Addition & Subtraction Unit

#### Strategies for Addition & Subtraction Unit

The Strategies for Addition and Subtraction Unit involves understanding the processes of addition and subtraction in order to solve problems and answer questions such as:

• If we know all of the parts, how can we find the whole?

• If we know the whole and one of the parts, how can we find the missing part?

• Given an equation, can you create an addition or subtraction situation to match it? How can you prove it matches the equation?

TEKS standards covered: 1.3A, 1.3D, 1.3E, 1.3F, 1.5D, 1.5G

### Algebraic Reasoning Unit

#### Algebraic Reasoning Unit

The Algebraic Reasoning Unit involves understanding number patterns within properties of numbers and operations in order to answer questions such as:

• How can you prove this number is odd or even?

• How can you use the relationship between addition and subtraction to solve problems in which the unknown may be any one of the terms in the equation?

• Give an equation in which the unknown may be any one of its terms, how can you create a situation to match it? How can you prove that your situation matches the equation?

TEKS standards covered: 2.7A, 2.7C

### Multiplication Unit

#### Multiplication Unit

The Multiplication Unit involves identifying a variety of models to represent the process of multiplication in order to learn how to use it to solve problems. Questions to answer may include:

• How do multiplication situations differ from addition situations?

• How do equal-sized groups model multiplication situations in the world outside the classroom? What real-world examples of equal-sized groups can you think of?

• How do arrays and area models represent multiplication situations in the world outside the classroom? What real-world examples of arrays can you think of?

• Given a multiplication equation, how can you create a situation to match it?

TEKS standards covered: 3.4D, 3.4E, 3.4F, 3.4G

### Multiplying and Dividing Whole Numbers Unit

#### Multiplying and Dividing Whole Numbers Unit

The Multiplying and Dividing Whole Numbers Unit involves using patterns and place value to develop strategies to multiply and divide whole numbers. Questions to answer may include:

• How are models useful for representing the processes of multiplication and division?

• How are the properties of place value (additive, multiplicative, base-ten & positional) useful in developing efficient procedures for multiplying and dividing whole numbers?

• How can mental math, rounding, and/or the use of compatible numbers help to determine whether the solution to a multiplication or division problem is reasonable?

TEKS standards covered: 4.4B, 4.4C, 4.4D, 4.4E, 4.4F, 4.4G, 4.4H

### Decimal Place Value Unit

#### Decimal Place Value Unit

The Decimal Place Value Unit involves understanding and representing the relative position, magnitude and relationships within the numeration system in order to answer questions such as:

• How can you use the additive property of place value to decompose this decimal number?

• How can you use the multiplicative property of place value to describe the meaning of each digit in the number 0.123?

• How can you use the base ten property of place value to explain the relationship between each of the digits in the number 5.555?

TEKS standards covered: 5.2A, 5.2B, 5.2C
