###
Solving Equations and Inequalities

Students will be divided into four groups and work on their assigned task to become an expert. They will match vocabulary terms with definitions and examples, use the “Pass the Pen” strategy to create and solve equations or inequalities, or write a real-world problem for an equation given. The experts will then teach these concepts to their peers.

###
Express Yourself

Students determine which expression is a truth or a lie by generating equivalent expressions.

###
Keep Your Balance!

**Students are introduced to solving one-variable, one-step equations using addition and subtraction through models and hands-on activities. The students will learn the substitution method of checking answers.**

###
Perfecting Percents

Students will engage in an activity that allows them to explore the different parts of percents: part, whole, and percent, and develop conceptual understanding of percents through the Concrete, Representational, Abstract (CRA) method of instruction.

###
Perfectly Proportional Percents

Students will collaborate to explain verbally how to solve percent proportions and scaling while showing their thinking.

###
Exploring Number Sense

Students will use manipulatives and a number path to identify numbers one less than or more than a given number.

###
How Does the Cookie Crumble?

Students will self-discover how to multiply mixed numbers by using background knowledge of estimation, computations, and real world application of a recipe.

**Texas Essential Knowledge and Skills Related to the Unit **

In fifth grade, students will be able to multiply and divide whole numbers, which will lead into multiplication and division of decimals in sixth grade. That same year, they will model products and quotients of decimals to the hundredths place. This concrete model will lead them to a better understanding of the algorithm in fifth and sixth grade.

As fifth graders, students will model multiplication and division of a fraction and a whole number. The following year, students are expected to multiply and divide all types of fractions.

In addition, during sixth grade, students are introduced to integers (negative whole numbers) and will be able to model and solve all operations with integers. All of the skills previously stated will lead students to be able to perform all operations of rational numbers without models (positive and negative fractions, decimals, and whole numbers) in seventh grade.

###
Determining Slopes from Equations, Graphs, and Tables

Given algebraic, tabular, and graphical representations of linear functions, the student will determine the slope of the relationship from each of the representations.

###
Using Measures of Center and Spread to Summarize Data

**Students will be able to use the measures of center and spread of a set of data to make summary statements regarding the applications of the data.**

###
Independent and Dependent Variable in Tables and Graphs

Students will use information in a real-world scenario to create a table or graph, translate the meaning of the table or graph, and identify the independent and dependent quantities.
