Take the class over the rainbow. Pairs or small groups follow directions to create a spectrograph. The pupils measure the angles formed by the different colors of the spectrum along with calculating the lengths formed by the spectrum and...

Get ready to set the standard! Pupils watch a video on how to graph a parabola from a quadratic in standard form without converting the form. Scholars learn how to find the axis of symmetry from the equation and from there the vertex....

It's time to crack open that piggy bank and see what's inside. First, count up the pennies, nickels, dimes, and quarters, identifying what fraction of them are dimes. Then calculate the total value of the coins, writing another fraction...

When it comes to rating educational calculators, this calculator is always near the top of this list. Now it's available as an app. There is a lot of calculator power wrapped up in this app. Not only is this a fully functioning...

We landed on the moon with less computing capabilities than you can find in this app! Here is a multiple function calculator that takes all the power you get from a handheld and adds the wonderful large screen that only a tablet can...

Middle and high schoolers construct a triangle using Cabri Jr. They construct squares on each of the legs and hypotenuse of the triangle. Pupils show that the area of the squares on the leg equal the area of the square on the hypotenuse.

Loans are rarely provided without a cost. Pupils evaluate the high cost of using a payday loan or payday advance through discussion and worksheets, and finally work in groups to develop short public service announcements...

Density: the reason a giant pumpkin will float, but a tiny cranberry won't. Lesson begins with a demonstration of two of the same-sized cubes having different densities. Then pupils take eight cubes, each of the same size, and have to...

Model the flight of a ball. Small groups collect time data for how long it takes to toss a ball between two people. The teacher leads a discussion about projectile motion to get the class thinking about how to calculate the equation of...

How high will it fly? Pairs build straw rockets and launch them at different angles and determine the height and horizontal distance of the flight path. Teams make conjectures about how the angle affects the measured distances and use...

Students define the slope of a line as rate of change. They investigate positive, negative, zero, or undefined slope using a graphing calculator. They determine the slope of a line when given the equation of the line.

Students examine the calculator. In this math lesson, students use the directions to learn how to use a calculator. Students apply the knowledge and solve problems using the calculator.

Students investigate the four basic operations of mathematics that are addition, subtraction, multiplication, and division. The use of a technology game is part of the lesson plan. They demonstrate the proper use of a calculator as part...

Here is a fun calculator trick, perfect for getting your learners ready for a day of exciting math. They multiply any single-digit number by 12,3456,789 to reveal an amazing result. Teaching notes are included on two of the slides.

Learners match a given velocity graph and sketch the corresponding position graph using a graphing calculator. After collecting data from their everyday life, students use specific functions on their calculators to create graphs and...

In this modeling data learning exercise, students use quadratic functions to model data using three different methods.  This learning exercise provides explanations and an example.  Additionally, students are given the steps to...

Students make mathematical argument using the concept of Limit. In this algebra instructional activity, student calculate the instantaneous rate of change from the linear graph. They use a TI-calculator to create a visual of the graphs.

Using TI-89, mathematicians explore and investigate Riemann sums to estimate the area under the graphs of intervals by drawing and illustrating rectangles. They review and practice the concepts of summation notation and area formulas to...

It's time to investigate patterns! First and second graders construct a paper weaving using a hundreds chart, then use the Ti-10 calculator to make patterns such as adding 3 each time. Learners remove multiples of three from the hundreds...

Pupils investigate how electrical usage is counted. In this electricity lesson, students research an electric bill and define terms such as watts and kilowatts. Pupils calculate the average electricity cost per year by using a...

This worksheet belongs to a four-part resource that gathers information from data tables to calculate percentages. The page introduces one problem and shares an explanation to the answer.

Students discover the relationships of the lengths of the sides of right triangles and right triangles using a series of drawings on dot paper. They investigate and solve problems of standard (customary and metric units) and non-standard...

From z-scores to probability. Learners put together the concepts from the previous lessons to determine the probability of a given range of outcomes. They make predictions and interpret them in the context of the problem.

Statisticians analyze a data set of student IQs by finding measures of central tendency and dispersion such as mean, median, mode, and quartiles. They practice using a graphing calculator to find the values and analyze box plots and...
