Lesson Planet: Curated OER

#### InteGreat

Hands-on investigation of Riemann sums becomes possible without intensive arithmetic gymnastics with this interactive lesson plan. Learners manipulate online graphing tools to develop and test theories about right, left, and midpoint...

Lesson Planet: Curated OER

#### Number Cube

Building a six-sided number cube has never been so easy. Just cut out the figure on the solid lines, fold on the dotted lines, connect the sides together using glue or tape, and there you have it!

Lesson Planet: Curated OER

#### Order of Operations Worksheets

Put your red pen down, it's time for your mathematicians to review students' work. Pupils are given one problem that has been solved three different ways to inspect its correctness and explain their thinking using academic language.

Lesson Planet: Curated OER

#### Finding Percent of Fractions

Sixth graders read word problems that involve finding the percent of an item, given the fraction.

Lesson Planet: Curated OER

#### Finding Percents

What is 75% of 200? The answer is 150. These are the types of questions students are prompted to solve, in a worksheet that reinforces finding percents of a number.

Lesson Planet: Curated OER

#### Rolle’s Theorem and the Mean Value Theorem

Using the derivative to apply the Mean Value Theorem and its more specific cousin, Rolle's Theorem, is valuable practice in determining differentiability and continuity on an interval. This presentation and accompanying worksheet walk...

Lesson Planet: Curated OER

#### Multiplying Polynomials

Without ever relying on the FOIL trick, this presentation carefully walks young algebrists through multiplying binomials by a monomial and by each other. Examples start easy, but move into complicated pairings of coefficients, positives...

Lesson Planet: Curated OER

#### Polynomial Operations

This overview of polynomial operations does a solid job of summarizing how a mathematician attacks adding, subtracting, and multiplying polynomials. With particular emphasis on combining like terms and when exponents do and do not...

Lesson Planet: Curated OER

#### Simplifying Radical Fractions

Rationalizing denominators of radical fractions is one of those skills that pulls together understanding of many different concepts. By carefully scaffolding from easy to hard examples and explaining each example step-by-step, this video...

Lesson Planet: Curated OER

#### Matrices

This accessible presentation presents the basics of matrices, from vocabulary through addition, subtraction, and scalar multiplication. With particular emphasis on positives and negatives, this method introduces learners to this useful...

Lesson Planet: Curated OER

#### Determinants and Cramer’s Rule

Practicing determinant calculations and their applications is the focus of this detailed skills practice instructional activity. A summary of steps at the beginning of each section keeps young mathematicians on track, while clear and...

Lesson Planet: Curated OER

#### Multiplicative Inverses of Matrices and Matrix Equations

Young mathematicians so often have a love-hate relationship with matrices and their inverses. They love the idea of a quick algorithmic way to solve systems of equations, but get stuck in the arithmetic precision required by the method....

Lesson Planet: Curated OER

#### Matrix Solutions to Linear Systems

The emphasis is on the mechanics of matrix reduction in this problem set and presentation. Clear steps and a summary of method directions open the student notes, followed by six problems that walk learners through Gaussian and...
