Lesson Planet: Curated OER

#### Simplify Algebraic Expressions (Basic)

To simplify or not to simplify, what should scholars do? Using several examples, the video works through the process of simplifying algebraic expressions. The resource restricts simplification to using the distributive property and to...

Lesson Planet: Curated OER

#### Simplify and Evaluate Algebraic Expressions 1

Evaluate the equivalence of expressions. A helpful video walks through the process of simplifying two expressions. Using values for the variables, the presentation evaluates the original expression and the simplified expression to show...

Lesson Planet: Curated OER

#### Transformations Resource

Transform your lesson for transforming functions. Scholars transform linear, quadratic, exponential, rational, and trigonometric expressions. They write their expressions to fit specific forms and identify the values of the resulting...

Lesson Planet: Curated OER

#### Transformations-Diagnostic

Change the way you teach about rewriting expressions. A diagnostic task asks learners to transform expressions in different ways. Given two linear expressions and two quadratic expressions, they rewrite them into the indicated forms.

Lesson Planet: Curated OER

#### Multi-Function Data Flyer

Explore different types of functions using an interactive lesson. Learners enter functions and view the accompanying graphs. They can choose to show key features or adjust the scale of the graph.

Lesson Planet: Curated OER

#### Incline

Study velocity while examining graphical representations. As scholars work with the animation, they discover the effect the height of an incline has on the velocity of the biker. They make conclusions about the slope of the line in terms...

Lesson Planet: Curated OER

#### Representing Functions of Everyday Situations

Functions help make the world make more sense. Individuals model real-world situations with functions. They match a variety of contexts to different function types to finish a helpful resource.

Lesson Planet: Curated OER

#### Factorising Expressions - Single Brackets

Use common factors to simplify expressions. The resource introduces factoring out the greatest common factor to simplify algebraic expressions. Worked examples include basic linear with numerical common factors to expressions that have...

Lesson Planet: Curated OER

#### Factorising Quadratics

Introduce factoring basic quadratics to your class. A video uses an example to introduce the concept of factoring a quadratic trinomial. All of the quadratics in the resource have a leading coefficient of one.

Lesson Planet: Curated OER

#### Simplifying Polynomials

Combine terms to help simplify. An introduction of like terms starts the discussion on simplifying polynomials. Playing the game "like terms or not like terms" soldifies the concept of like terms. The video shows how individuals can...

Lesson Planet: Curated OER

#### Integer Combinations—Postage Stamps Problem (HS Version)

It seems the post office has run out of stamps! Learners build all the values of postage available if the post office only sells five- and seven-cent stamps. The task provides an opportunity to create an expression in two variables and...

Lesson Planet: Curated OER

#### Factoring a Degree Six Polynomial

Within collaborative groups, scholars factor a degree six polynomial. They can factor the polynomial using many different strategies — a great way to prompt mathematical discussion.

Lesson Planet: Curated OER

#### Monomial Factors of Polynomials: Mystery Boxes

Shortcut the work in finding total volumes. Pupils determine a polynomial expression that would represent the combined volume of three boxes. Each box has the same height, and the scholars rewrite the expression by factoring out the...

Lesson Planet: Curated OER

#### Linear and Exponential Functions

Provide a continuous progression to linear and exponential functions. Pupils continue to work with the discrete functions known as sequences to the broader linear and exponential functions. The second unit in a series of nine provides...

Lesson Planet: Curated OER

#### Factoring

Factor in this resource when teaching how to factor polynomials. Scholars use algebra tiles to factor linear and quadratic expressions. They practice their skill by working on example problems from a worksheet.

Lesson Planet: Curated OER

#### Transformation II

Develop a solid understanding of the manipulation of expressions to produce equivalent expressions. Given an expression, pupils rearrange it to create a new one. Their new functions must match the structure of the model expressions.

Lesson Planet: Curated OER

#### Birthday Card

Add a twist to the practice of simplifying expressions. The task asks scholars to decode a mathematical puzzle using their knowledge of expressions. If they are able to write and simplify the expression, the mathematics behind the puzzle...

Lesson Planet: Curated OER

#### Transformation I

Rewriting expressions in different forms is an essential algebra skill. Support the development of this skill by using a task that asks scholars to begin with a linear, quadratic, and rational expression and then manipulate them into a...

Lesson Planet: Curated OER

#### Factoring the Difference of Squares

Explore a special pattern in factoring quadratics. The video instructor shows many examples of factoring binomials that are the difference of squares. The examples vary from single to multiple variables and multiple coefficients.

Lesson Planet: Curated OER

#### Para-Ball-A

Analyze the flight of a thrown ball. Learners determine the maximum height of a thrown ball and the time it takes to hit the ground given its initial speed. They continue to review different scenarios with different maximums or different...

Lesson Planet: Curated OER

#### Complex Fractions

Complex fractions are fractions divided by fractions—complicated, right? The video introduces the class to algebraic complex fractions. With the introduction to variables in the denominator, it is important make sure the denominator is...

Lesson Planet: Curated OER

#### Like Terms, Multiplication and Division

Introduce the class to simplifying algebraic expression using multiplication and division. Showing the connection of the rules for exponents between numerical expressions and algebraic expressions, the video works several examples of...

Lesson Planet: Curated OER

#### Like Terms, Addition and Subtraction

It is not good enough to have the same variable, they must have the same exponents too. The video introduces the class to like terms, while giving the definition of like terms and providing examples of combining like terms through addition.
