Properties of Operations
Explore the definitions of algebraic properties through a hands-on activity. Individuals cut and paste examples and match them to the correct properties. After examining the provided examples, pupils create examples of their own.
Illustrative Mathematics
Numbers in a Multiplication Table
Identifying patterns is a crucial skill for all mathematicians, young and old. Explore the multiplication table with your class, using patterns and symmetry to teach about square numbers, prime numbers, and the commutative and identity...
EngageNY
Proofs of Laws of Exponents
Apply pupil understanding of exponent properties to prove the relationships. In the sixth lesson of the series, individuals are expected to prove relationships using mathematical statements and reasoning.
Beyond Benign
Packed Up Properties
Determine physical properties of potential packaging materials. Continuing from previous lessons in the series, the resource asks groups to identify physical properties of the substances. They test for conductivity, solubility, water...

Module 10: Matrices Revisited
A matrix is just a fancy way of making a table. Young scholars explore operations with matrices with the first lessons in the final module of a 10-unit Algebra II series. After adding, subtracting, and multiplying matrices, pupils use...
EngageNY
Proving Trigonometric Identities
Young mathematicians first learn the basics of proving trigonometric identities. They then practice this skill on several examples.
Alabama Learning Exchange
The Birth of Rock(s) - Identifying Rock Types
Young scientists investigate types of rocks in this instructional activity. They collaborate to examine groups of rocks, make written descriptions of them, and use websites to help them identify the types of rocks they are.

Matrix Multiplication Is Distributive and Associative
Learn the ins and outs of matrix multiplication. After discovering the commutative property does not apply to matrix multiplication in a previous activity in the series, pupils now test the associative and distributive properties. The...
EngageNY
Using Matrix Operations for Encryption
Data encryption is an important security measure for sensitive data stored on computers. Pupils learn how to utilize matrices for creating code. They also get a great review of matrix multiplication, inverse matrices, and the identity...
EngageNY
Basic Trigonometric Identities from Graphs
Have young mathematicians create new identities! They explore the even/odd, cofunction, and periodicity identities through an analysis of tables and graph. Next, learners discover the relationships while strengthening their...
EngageNY
Factoring Extended to the Complex Realm
A solution will work one way or another: find solutions, or use solutions to find the function. Learners use polynomial identities to factor polynomials with complex solutions. They then use solutions and the Zero Product Property to...
Curated OER
Real Number System
Ninth graders discuss the real number system and its' properties. In this algebra lesson, 9th graders discuss rational, irrational, closure, real numbers and the distributive property of algebra. They solve problems using these...
EngageNY
Complex Numbers and Transformations
Your learners combine their knowledge of real and imaginary numbers and matrices in an activity containing thirty lessons, two assessments (mid-module and end module), and their corresponding rubrics. Centered on complex numbers and...
Curated OER
Fruity Math
Students solve one step linear equations. In this algebra lesson, students manipulate their variables and numbers to answer each problem. They make sure the equations stay balanced at all times.
Curated OER
Pattern Search
Third graders review the commutative and associative property in mathematics.  Using a worksheet, they work together to identify the patterns between the 32 triangles.  To end the lesson plan, they create their own array and exchange it...
Curated OER
Watts Up Doc?
Students examine the wattage of a light bulb using math. In this algebra lesson, students find the inverse square of given parameter. They work in groups collecting and analyzing data.
Curated OER
Determining the Age of Fossils
Students examine the concept of radioactive dating. In this radioactive dating lesson, students investigate how to determine the ages of fossils and rocks as they learn about half-life radioactive decay. 
Curated OER
Totem Poles -- Storytellers of Long Ago
Third graders discover the main purpose for totem poles was to communicate with others.  In groups, they compare and contrast the four types of totem poles and the various symbols used.  They write their own stories based off of pictures...
Curated OER
Do it With Dominoes
Students explore modes for addition.  In this K-2 mathematics lesson, students investigate the four models of addition (counting, sets, number line, and balanced equations) using dominoes.  Students examine the relationship...
Curated OER
Fractals
Students explore the concept of fractals.  In this fractal lesson plan, students use applets to explore Koch's Snowflake, Sierpinski's Triangle, and other fractals.  Students develop these concepts through exploration and teacher guided...
Curated OER
Penny Moves
Students explore math functions by completing a worksheet in class. In this spatial movement lesson, students utilize a four square grid and a penny to practice moving the coin horizontally, vertically and diagonally as instructed....
