Calculator Teacher Resources

Calculators ... they are more efficient than tables. Using two 30-60 right triangles, the segment of a playlist on geometry shows that trigonometric ratios for an angle are the same independent of the size of the triangle. The video...

Branch out with a tree diagram. A presentation on complex probability explains the process of creating a tree diagram to represent the possible outcomes in a scenario. It then uses the diagram to calculate the probabilities of each of...

Explore the effect sample size has on margin of error and confidence interval. The instructor calculates the margin of error of fictional data. He shows how the calculation changes when the sample size changes while keeping the other...

A series of word problems relate to money and real world applications. Learners are encouraged to use calculators to solve each of the problems, however they can be solved with out the use of a technological device. Note: All money is in...

Eighth and ninth graders solve and complete 6 different types of word problems. They use their knowledge to solve a number of word problems involving exponents, square roots and scientific notation and use a calculator to perform the...

Work smarter, not harder! Learn a function of the calculator that assists with creating a table of values. The calculator does the work of substituting values and finding the input-output pairs.

In this math worksheet, learners use a graphing calculator to solve nine multi step problems with order of operations with exponents. Directions and diagrams about what buttons to push are included.

Do bigger sails mean that the sailboat goes faster? Middle and high schoolers compare sailboats, and learn that simply calculating sail area is not enough. A slideshow presentation demonstrates how to calculate the Sail Area to...

Take young mathematicians' understanding of geometry into the real world with this upper-elementary math lesson. Given the floor plans of a historic building in Tennessee, young scholars are asked to calculate its area and perimeter as...

In this math worksheet, students use calculators to complete seven problems with area and volume. Pictures are shown along with questions, and students perform calculator solutions to the questions

So, exactly, what does it look like? The easily usable graphing calculator allows pupils to visualize the graph of equations and inequalities. The interactive supports any algebraic graph needed for high school mathematics and then some.

How much is owed? A calculated resource introduces the simple interest formula with a video that describes how to use it. Classmates then show what they know by answering questions within a simple interest worksheet.

A wonderful resource just waiting to be used. Provide learners with a complete explanation on how to calculate the area of a rectangle. After this process is covered, they will see how they can use rectangles to calculate the area of...

Before beginning this money math activity, discuss with scholars why calculating change is an important life skill. They examine the prices for fruit on a snack menu and observe three customer scenarios. For each one, scholars determine...

These 52 questions ask students to calculate moles from masses of ceratin elements, or the mass of a certain umber of moles.  This is excellent practice with varying degrees of difficulty.

Mathematicians need to know that not all numbers are rational. We approximate irrational number with rational numbers. That is why a calculator may be misleading. This task give learners an opportunity to see how rounding a number and...

Not all data falls on a perfect line. After collecting class data on shoe size and height, scholars create a scatter plot and draw a line of best fit. They calculate the residual for their own data points, and then create residual plots...

Under which condition should you calculate a conditional probability? An educational video explains in detail the notation and calculations involved when finding a conditional probability. Using Venn diagrams to organize the information,...

Do your pupils already have knowledge of moles and mass? If so, this is the next step for the chemistry classroom. The video segment, while short in length, is filled with demonstrations on how to perform mole calculations involving both...

Calculate theoretical probabilities and compare them to experimental probabilities. Pupils build on their knowledge of experimental probabilities to determine theoretical probabilities. Participants work several problems with the...
