Remove any ambiguity about using a helpful resource. Individuals use an interactive to find the number of triangles that fit given conditions. They find that some conditions can result in more than one triangle in the ambiguous case.

Stack the like terms to add vertically. The resource contains a visual aid to help with the addition of polynomials using the vertical method. Pupils use the aid to calculate the sum of two polynomials.

Different forms, same line. Young mathematicians investigate the standard form, slope-intercept form, and point-slope form of a linear equation. An interactive has them adjust lines on a coordinate plane to see changes in each form of...

Functions are special types of relations, but what makes them so special? Pupils use an interactive to slide a vertical line across six different graphs. Ten challenge questions then assess understanding of functions.

What does it mean to take the mean of the mean? An easy-to-use interactive has users adjust the mean ages of different samples. Finding the average of these sample means gives an estimate of the population mean.

Limits are made easy through graphs and tables. An easy-to-use interactive lets users change a function on a coordinate plane. They relate graphs and tables to the limit at a specific value.

A one-sided limit is no less important than a two-sided limit. Young mathematicians use an interactive to match limit notation to graphs. The exercise requires interpreting how one-sided limits connect to features of graphs.

There are an infinite number of reasons to use the resource. Scholars drag vertical and horizontal lines to the graph of a rational function to identify all asymptotes. They investigate the connection between asymptotes and limits to...

Building trigonometric basics here will last a mathematical lifetime. Learners expand on the previous lesson in a 36-part series by examining relationships between the sine and cosine of complementary angles. They also review the...

So a cylinder does not have to look like a can? By expanding upon the precise definition of a rectangular prism, the instructional activity develops the definition of a general cylinder. Scholars continue on to develop a...

How are systems related? Build on your pupils' previous knowledge of solving systems of equations by introducing systems of inequalities. Learners explore similarities between systems of equations and inequalities to make a strong...

Log the resource on logarithms for future use. Learners review and explore properties of logarithms and solve base 10 exponential equations in the 12th installment of a 35-part module. An emphasis on theoretical definitions and...

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...

Select items to purchase from a store, add up the total cost, then estimate the total cost! Kids count out the money needed to make the purchase and pay for the items. An excelent way to connect real life math and estimation!

Get your learners up and moving, all while reviewing numbers on the number line! For this activity, learners are grouped in teams outdoors. The teacher will have already created number lines on the ground (with chalk, tape, etc.), and...

Young scholars review solving equations. They solve an inequality and discuss how to graph it. Students work together on one inequality and then graph two on their own. This lesson contains links to a PowerPoint and a worksheet.

Sixth graders review the different types of graphs (bar, line, pictograph) They predict the data set they can garner several boxes of conversation hearts. Students record their data using an Excel spreadsheet. They create a graph based...

Fourth graders engage in a lesson that is about the concept of rounding decimals. They review place value and focus it upon the practice of rounding. Students use 10 base decimal grids or models to help make connections with the skill.

Explore metric measurement, recording data, and creating an electronic spreadsheet displaying results with your math class. Scholars will measure the length of their smiles, record the measurements, and represent the results on an...

Students explore inequalities to determine the optimal solution to maximize a profit for a company. In this linear programming lesson, students discover how to graph inequalities and how to determine the algebraic representation of a...

Third graders investigate congruent polygons through dance. In this congruency lesson, 3rd graders do the "brain dance" as a warm up. They review polygon names by singing "The Polygon Chant," before mirroring congruent shapes with a...

Youngsters solve division word problems. They will make their own division word problems using objects in equal groups. They share how they solved their problem with the class. Division worksheets are included to support the process....

In this 2-D shapes lesson, kindergarteners review plane shapes attributes. They engage in a shape hunt in the classroom and create art using plane shapes. A good, hands-on lesson!

High schoolers analyze environmental science data using Math. They do research about renewable energy, gather data, create graphs and interpret their findings. Then the group presents their arguments persuasively using their findings to...
