Collaborative learners will see the geometric addition of functions by graphing the sum of two graphed curves on the same coordinate plane. This task then naturally flows into giving learners the algebraic representation of the curves...

Give AP Calculus classes the opportunity to check the accuracy of their calculations! A calculus activity involves the collection of data, the application of mathematics, and the analysis of the accuracy of results. Young mathematicians...

A cross-curricular resource that takes the electoral votes and allows your learners to organize and analyze the data. Young voters can determine which states are more influential and interpret the dotplot provided for more data....

Young scholars explore the concepts of Sierpinski's triangle, ratios, and concentrations. In this exploratory lesson, students are given three problems to solve. Young scholars learn about Sierpinski's triangle, how to calculate mpg for...

This can be used as a critical thinking exercise in congruence or as a teaching tool when first introducing the concept. Four octagons are arranged in such a way that a square is formed in the middle. With this information, geometry...

Your young landscapers do concentration calculations in this problem dealing with mixing fertilizer. Learners use and analyze rational expressions within this context.

Mathematicians practice communicating why the sum of two multiples of a number results in another multiple of that number. Encourage learners to construct a viable argument by applying the distributive property or by drawing a diagram....

This resource sneaks in the math so your learners will be adding and subtracting positive and negatives on a number line while thinking they are mapping out houses. The activity starts by putting houses the appropriate distance away from...

Spread your knowledge of spreadsheets. The first of five tutorials in the Spreadsheet Data Analysis unit introduces the basics of spreadsheets. It shows future data analysts how to organize and format tables, and how to use functions to...

The t-test tutorial will fit your needs to a T. After calculating the mean, sum of squares, standard deviation, and variance of two data sets on a spreadsheet, scholars learn to calculate the t-values. They then learn to use the TTEST...

Designed as a follow-up to the lesson plan titled Watch Out for Parenthesis 1, this activity asks young learners to write an equation for the calculation described with words rather than numbers and symbols. The treasure that 5th...

Start off with the definition of the imaginary number i, then have your class practice simplifying expressions involving powers of i and look for patterns. See how the cyclic nature of powers of i translate to sums of powers of i.

Put those thinking hats on and look at all the possible outcomes from rolling two different four-sided dice. The challenge in this problem is finding all the combinations when adding and subtracting the numbers from each die and creating...

A 27-page packet full of math games and activities builds on algebra, measurement, geometry, fractional, and graphing skills. Young mathematicians participate in math games collaboratively, promoting teamwork and skills practice.

Here is a lesson that starts with having geometers translate points using compass directions into an accurate picture of the problem. Then they must use their knowledge of the Pythagorean theorem or similar triangles to solve. This makes...

Your algebra learners build a quadratic function in this task of counting the blocks used to build objects. The arithmetic sequence that shows up brings up a shortcut to the long addition using the Gauss Method. Eventually, learners...

If you've always wanted to know more about spreadsheets, here's a perfect resource for you. A self-paced tutorial introduces how to autofill and copy formulas in a Google sheet or Excel spreadsheet. It also shows users how to find range,...

Gain a little interest in functions with a real-life task. Young scholars analyze home loan data with a geometric sequence and series. They use the models to make predictions about the total loan payments at certain intervals in a...

This activity looks at writing expressions to represent perimeter of a rectangle and then considers the concept of equivalent expressions and the distributive property in more detail. 

Students connect literature (story Jelly Beans for Sale by Bruce McMillan) to math concepts. In these estimating and money lessons, students work with jelly beans, unifix cubes, pennies, nickels, dimes, and quarters, to estimate and make...

For the purpose of obtaining results for several cones simultaneously, you can introduce into the calculator the multiple values of the cone. The calculator then will automatically sum the cone volume results which provides the...

In this activity, students calculate Riemann sums. They demonstrate when the Riemann sums will over-approximate a definite integral. They also observe the convergence of Riemann sums as the number of subintervals get larger.

Can you beat the calculator? Your task is to find the sum of all even numbers between two and any selected two-digit even number. If you can find the number pattern, you are sure to beat the calculator every time. Links to other "Beat...

In this Computer Algebra System (CAS) activity students use Riemann sums to estimate the distance traveled on a trip at various speeds. They utilize the concept of Riemann sums to calculate the area under a curve. Students find limits of...
