New Horizons began its journey to Pluto in 2006. Ten years later, it continues its mission. In that time, scholars have surely grown, but how much more will they grow by the time New Horizons reaches its destination? Find out with an...

Observe and demonstrate how to calculate state sales taxes. Learners create a sales tax chart by calculating the sales tax amount and tax inclusive retail price for school store items, then calculate the subtotals, sales tax amounts, and...

The fifth portion of the 25-part series introduces probabilities calculated from outcomes that are not equally likely. Class members use tables to calculate probabilities of events, add outcome's probabilities, and find...

Third graders increase their knowledge of how to make change with dollars and cents by correctly identifying coins along with their values and then using coins to make an assigned amount which will be written on envelopes. They then...

Time flies when you're teaching math! Okay, maybe not for everyone, but this lesson will have your young mathematicians calculating elapsed time before you know it.

Plumb the depths of the Submarine Ring of Fire and explore seismic waves with this lesson. Junior geologists simulate s-waves and p-waves, calculate their speeds, and then apply the data to discover the material that makes up inner...

Students investigate how to make change when purchasing items.  In this making change lesson, students examine a scenario to calculate the correct change.  Students play Bingo based on information and calculations to determine...

In exploring the concept of complex roots, students find the axis of symmetry and roots of parabolas.  Then, they discuss what makes a solution complex and how to identify functions with complex roots.

Show your classes how different means can represent the same data. Individuals collect household size data and calculate the mean. Pupils learn how handling of the data influences the value of the mean. 

We know that sample data varies — it's time to quantify that variability! After calculating a sample mean, pupils calculate the margin of error. They repeat the process with a greater number of sample means and compare the results.

Time for statistics and learning to overlap! Learners examine Venn Diagrams as a means to organize data. They then use the diagrams to calculate simple and compound probabilities.

Twelfth graders simulate making purchases based on infromation located in supermarket flyers. Working in groups, 12th graders alternately make purchases and calculate change from a given amount. Students role play common bank...

Learners calculate the square root of a given number using carpenter's square measurements. In this math lesson, students relate this method on the Pythagorean theorem. They answer practice problems after the exploration activity,

Students examine how to solve word problems by recognizing patterns. They create tables to help them visualize the problem. They discover that some problems can be solved by recognizing a pattern,

In this finding the sums of word problems worksheet, students add the one-digit word numbers and numerals and use the pictures to assist them. Students solve four problems.

First graders demonstrate an understanding of subtracting one from a number of ten or less using manipulatives, work with calculators to solve subtraction problems, and create subtraction number sentences to solve on the calculator.

Do your learners like dinosaurs and theme parks? An ambitious lesson invites learners to put together a plan for supplying dinosaurs for a new theme park. Pupils work together in groups to come up with their plan, which must include a...

Using your graphing calculator, find all the rational zeroes of a polynomials by using the Rational Zero Theorem. Divide polynomials using the Remainder Theorem and the Factor Theorem and then graph it to find the number of real roots.

Challenge young mathematicians to buy classroom supplies by staying within the means of a $1,000 budget. The mathematical activity provides learners with the opportunity to decide what items from the supply list would benefit a class of...

One of the most common, everyday applications of math is dealing with money. This single problem calculating how much change Margie receives is more involved than it appears at first glance. An understanding of how fractions and decimals...

Students investigate the concepts of adding, estimating, and ordering. The lesson uses the alphabet as an example illustration. The students practice the calculations in class in order to ensure mastery.

Third graders explore math functions by completing a worksheet in class. In this word problem solving lesson, 3rd graders read a book titled Counting on Frank by Rod Clement and utilize the information in the story to answer study...

There are many ways to approach finding the rational approximation of an unknown square root. Here is a problem that will help math learners make a connection between square roots and their order on a number line. As usual, determine two...

The class checks to see if the formula for finding powers of a complex number works to find the roots too.  Pupils review the previous day's work and graph on the polar grid. The discussion leads the class to think about...
