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

### Addition and Subtraction Unit

#### Addition and Subtraction Unit

STANDARDS COVERED:

**K.3 Number and operations**

**K.3A **

Model the action of joining to represent addition and the action of separating to represent subtraction. **K.3B **

Solve word problems using objects and drawings to find sums up to 10 & differences within 10. **K.3C **

Explain the strategies used to solve problems involving adding and subtracting within 10 using spoken words, concrete and pictorial models, and number sentences.

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

- If we put the beans in this jar with the beans in this bowl, how many beans will there be?
- If we start with this many beans and give three beans away, how many beans will there be?

## Grade 1

### Equivalence Unit

#### Equivalence Unit

The Equivalence Unit involves understanding the meaning of the equal sign in order to answer questions such as:

- If I have 5 red counters and 4 yellow counters on one side of the equal sign, how many yellow counters must I put with two red counters to equal the number of counters on the other side of the equal sign?
- If I have 7 on this side of the equal sign, what numbers cans I put on the other side of the equal sign to make a true statement?

**TEKS standards covered: 1.5E**

## Grade 2

### Addition and Subtraction Unit

#### Addition and Subtraction Unit

The 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?
- How can you use place value to explain the strategies you used to solve this addition (subtraction) problem?
- Given an equation, can you create an addition or subtraction situation to match it? How can you prove your situation matches the equation?

**TEKS standards covered: 2.4A, 2.4B, 2.4C, 2.4D**

## Grade 3

### Comparing Fractions

#### Comparing Fractions

The Comparing Fractions Unit involves representing fractional parts of whole objects, lines, and sets in order to answer questions such as:

- Why must we use the same “whole” when comparing fractional parts?
- How can you prove that fractions are equivalent when using an area model such as pattern blocks or tangrams?
- How can you prove that fractions are equivalent when using a linear model such as a strip or number line?
- How can you prove that fractions are equivalent when using a set model such as 2-color counters?

**TEKS standards covered: 3.3F, 3.3G, 3.3H**

## Grade 4

### Adding and Subtracting Fractions Unit

#### Adding and Subtracting Fractions Unit

The Adding and Subtracting Fractions Unit involves using a variety of methods to join or separate parts referring to the same whole. Methods may include replacing mixed numbers with equivalent fractions; using properties of operations and the relationship between addition and subtraction; and using visual models of fractions. Questions to answer may include:

- Why must we use the same “whole” when adding or subtracting fractional parts?
- How can a number line represent adding or subtracting fractions?
- How can benchmark fractions help to determine whether a sum or difference makes sense?

**TEKS standards covered: 4.3A, 4.3B, 4.3E, 4.3F**

## Grade 5

### Products and Quotients with Decimals Unit

#### Products and Quotients with Decimals Unit

The Products and Quotients with Decimals Unit involves using patterns and place value to develop strategies to multiply and divide decimals. Questions to answer may include:

- How are the properties of place value (additive, multiplicative, base-ten & positional) useful in developing efficient procedures for multiplying and dividing decimals?
- How can mental math, rounding, and/or the use of compatible numbers help to determine whether a solution is reasonable?
- Given an equation involving finding products and/or quotients with decimals, how can you create a situation to match it?

**TEKS standards covered: 5.3D, 5.3E, 5.3F, 5.3G**
