###
Lines of Symmetry

Students will work collaboratively with a partner to discover what is a line of symmetry.

###
Composing and Decomposing a Number

In this lesson, students will learn how to compose a number with base 10 blocks, decompose a ten, and then compose the same number a different way.

###
Courts of Measure

Students will use measurement tools to measure the dimensions of the basketball court and calculate the area of the court.

###
Equations in the Real World

**Students will create and solve equations with variables on one side before comparing the equation with another to determine at what rate they will be equal. **

###
Mission Possible—The Hierarchy of Polygons

The students participated in three missions that required them to independently classify two-dimensional quadrilaterals in a hierarchy of sets and subsets using a graphic organizer based on their attributes and properties.

###
Balancing Act

Given a prompt, students will solve a multi-step equation using concrete and/or pictorial models.

Students learn to to use proportional relationships to describe dilation; explain proportional and non-proportional relationships involving slope; and use proportional and non-proportional relationships to develop foundational concepts of functions.

###
9 OnTRACK Grade 8 Math: Expressions, Equations, and Relationships

Students will learn to develop mathematical relationships and make connections to geometric formulas; use geometry to solve problems; use one-variable equations or inequalities in problem situations; and use multiple representations to develop foundational concepts of simultaneous linear equations.

###
5 OnTRACK Grade 8 Math: Two-Dimensional Shapes, Measurement, and Data

Students will learn to develop transformational geometry concepts and to use statistical procedures to describe data.

###
6 OnTRACK Algebra I: Properties and Attributes of Functions

Students will learn how to use the properties and attributes of functions.

###
6.08 Bonus Video: Law of Sines—The Ambiguous Case

The Law of Sines can be used to solve for sides and angles of oblique triangles. However, in some cases more than one triangle may satisfy the given conditions. We refer to this as an ambiguous case.

###
Math Problem Solving CAN DRIVE good problem solvers!: 1st grade CAN Drive

**Students will help the principal collect cans for a can food drive. The students will be able to solve math word problems using the UPS✓ (UNDERSTAND what the problem is asking, make a PLAN, SOLVE the problem, and then CHECK to see if the answer makes sense) song/strategy, draw to show their work, and write a number sentence to go with their problem. **

###
Breakout with Linear Relationships

Through a collaborative breakout station format, students will access prior knowledge to develop a deeper understanding of the relationships of slope through proportional relationships represented by unit rate and linear non-proportional relationships. A variety of representations will be practiced through scenarios, tables, graphs, and equations.

###
Study Edge Statistics

In Statistics, students build on the mathematics knowledge and skills from Kindergarten–grade 8 and Algebra I, broadening their knowledge of variability and statistical processes. Students will study sampling and experimentation, categorical and quantitative data, probability and random variables, inference, and bivariate data. Students will connect data and statistical processes to real-world situations and extend their knowledge of data analysis (TAC §111.47(b)(3)).

This video book is brought to you by TEA and Study Edge. It may be used to teach an entire Statistics course or to supplement traditional Statistics textbooks.

###
Study Edge Precalculus

Precalculus is the preparation for calculus. The course approaches is designed to strengthen and enhance conceptual understanding and mathematical reasoning used when modeling and solving mathematical and real-world problems. Students systematically work with functions and their multiple representations. Precalculus can deepen students' mathematical understanding and fluency with algebra and trigonometry and extends their ability to make connections and apply concepts and procedures at higher levels. Students will investigate and explore mathematical ideas, develop multiple strategies for analyzing complex situations, and use technology to build understanding, make connections between representations, and provide support in solving problems (TAC §111.42(b)(3)).

This video book is brought to you by TEA and Study Edge. It may be used to teach an entire Precalculus course or to supplement traditional Precalculus textbooks.

###
Transformations of Absolute Value Functions

Given an absolute value function, the student will analyze the effect on the graph when f(x) is replaced by af(x), f(bx), f(x – c), and f(x) + d for specific positive and negative real values.

###
2.07 Lurking and Confounding Variables

In this video, students learn the difference between lurking and confounding variables and how they affect results.
