On this interactive website students practice various math skills using a real life scenario at an igloo. Those skills include counting by ones, fives and tens up to fifty.

On this interactive website students practice various math skills using a real life scenario. Those skills include identifying 3D objects, identifying the similarities and differences in prisms and pyramids, and drawing 3D shapes such as...

On this interactive website students practice various math skills using a real life scenario at a toy store. Those skills include describing the features of pyramids, prisms, cones, cylinders and spheres.

On this interactive website students practice various math skills including naming prisms and pyramids, drawing cross sections of prisms and pyramids, and exploring three-dimensional views.

Teachers, this is the place to come for fraction lesson plans if you teach elementary learners. All the topics have a number of resources available from which to choose.

On this interactive site students learn to arrange numerous events from unlikely to very likely.

Different approaches to incorporate problem-solving skills into the elementary mathematics classroom.

The purpose of this task is to use technology to study the behavior of some exponential and logarithmic graphs and to manipulate some explicit logarithmic and exponential expressions. Aligns with HSF-LE.A.4, F-BF.B.5, and F-IF.C.7.e.

Experiment with a spring that is connected to a wall to see what happens to the oscillation when you change the mass, spring stiffness, or damping. Students can also change the starting position. Site includes equations to help students...

[Free Registration/Login may be required to access all resource tools.] Multiply matrices by scalars to produce new matrices, e.g., as when all of the payoffs in a game are doubled.

This lesson details graphing logarithmic functions. The lesson explains the relationship between the graph of the logarithm and its inverse. The site gives examples of logarithmic graphs of base 2, 3, and e. Shifts in logarithmic graphs...

A rigid motion of the plane is a map of the plane to itself which preserves distances between points. The purpose of this task is to use fixed points as a tool for studying and classifying rigid motions of the plane, i.e., translations,...

Students will practice counting and number identification with this activity which can be good for a math center. The teacher gives students the counting mat and many small objects to count with. Students will read the numbers and...

An overview of fractional (i.e., rational) exponents, including an example and practice problems with solutions.

Provides an introduction to probability. Includes examples, two videos, and links to additional resources, e.g., exercises to try. There are also problems and discussions of them in the Comments section.

An explanation of how to write a paper that reports statistical information and analysis.

Ahoy Matey! Join PBS Kids characters Peg + Cat to explore fair sharing and solve math problems to help a group of cranky pirates divide things fairly. Children will separate sets of objects into equal groups and divide single objects...

Practice checking if sample space diagrams match a compound event. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

In this exercise, students practice multiplying fractions by fractions word problems. Students receive immediate feedback and have the opportunity to get hints and try questions repeatedly.

Find the range of values of one variable that corresponds to a given value of the other variable in a system of two-variable linear inequalities. Students receive immediate feedback and have the opportunity to try questions repeatedly,...

Rewrite some elaborate exponential expressions that involve fractional exponents and radicals. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Rewrite exponential expressions (where the exponent can be a fraction) using the properties of exponents. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Multiply complex numbers by single terms that are either real or imaginary. Students receive immediate feedback and have the opportunity to try questions repeatedly or receive hints.

Find the magnitude of a vector. You'll see vectors given in graphs, given in component form, and given by initial and terminal points. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a...
