The Mathematics Assessment Project aims to bring the Common Core State Standards (CCSSM) to life in a way that will help teachers and their students turn their aspirations for achieving them into classroom realities. The project's free...

An explanation of how to use our curated resources for Eureka Math / EngageNY in 3-8 grade math classrooms.

Dr. Math responds to a question about how to determine if two triangles are similar. The Dr. goes into detail about the process and gives several examples that are worked out for you.

This website provides information about and tools and resources to support the Common Core State Standards for Mathematics (CCSSM).

Test your math vocabulary for properties of operations in this online car racing game.

A clear explanation of how to multiply a matrix by a vector and a matrix by a matrix. A follow-up page provides additional examples.

This illustrated math lesson shows how important levels of accuracy in measurement are. The answer can be different since a scale only accurately weighs to the nearest tenth of a gram instead of to the nearest hundredth of a gram. Aligns...

This resource provides information about the commutative and associative properties of multiplication.

Contains detailed information on absolute values for complex numbers.

This resource provides information about commutative and associative properties of addition.

Provides a thorough step-by-step approach to combining like terms. Takes the student through important vocabulary used, as well as examples to help explain the topic. Several pages of notes are offered along with relevant links at the end.

Given a complex number in rectangular form, write it in polar form. And given a complex number in polar form, write it in rectangular form. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a...

Solve word problems that involve general triangles using trigonometry. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Practice solving word problems by dividing fractions by fractions. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Observe students while they complete the following sheet to see how they discuss and match the numbers with the visual representation. Included is a score sheet to record data.

Purplemath gives several examples which clearly show the process of completing the square to find the maximum and minimum solutions to a quadratic equation.

[Free Registration/Login may be required to access all resource tools.] A collection of resources that teaches students that the zero and identity matrices play a role in matrix addition and multiplication similar to the role of 0 and 1...

The principal purpose of the task is to explore a real-world application problem with algebra, working with units and maintaining reasonable levels of accuracy throughout. Aligns with N-Q.A.3, N-Q.A.1, and N-Q.A.2.

This task is about farm-workers who are harvesting two fields. Students are presented with a scenario involving two teams of workers, two different sizes of fields, and work spread out over two days. They must calculate how many...

Given the height and volume of a certain cylinder, Jill uses the volume formula to compute its radius. If a second cylinder has the same volume as the first, but is 100 times taller, what is its radius? Aligns with A-SSE.A.1.

A landscaping company prepares two mixtures of fertilizer. In this task, young scholars investigate what happens to the value of an expression when a quantity is changed. Aligns with A-SSE.A.1 and A-SSE.A.1.b.

The purpose of this task is to apply translations and reflections to the graphs of the functions f(x)=cos x and g(x)=sin x in order to derive some trigonometric identities. There are also rotations 180 degrees about points on the x-axis...

In this task, students will rewrite fractions as a sum of distinct unit fractions. To solve the problem, students will rewrite a simple rational expression and will need to study the arithmetic of these unit fractions with a variable in...

For this task, students investigate the properties of a polynomial of degree d > 0. The task relates to the Fundamental Theorem of Algebra. Aligns with A-APR.B.2.
