Comparing equivalent fractions is one of the most difficult math concepts to teach to youngsters. How can numbers that look so different actually represent the same thing? This presentation takes a lot of the mystery out of equivalent...

If you're looking for a presentation to assist you in your teaching of triangles, this one could be for you. In it, learners are shown how triangles are classified by the size of their angles and by their sides. These are tricky concepts...

Aspiring astronomers study stars. They compare stars and explain the relationship between radius, mass, and diameter. By creating a star simulation, they discover how a binary star system's orbit can cause changes in the observed...

Middle and high schoolers use a spreadsheet to graph data. In this graphing lesson, learners determine how two parameters are correlated. They create a scatter plot graph using a computer spreadsheet.

Where are all the numbers? Scholars practice with number sequences in different formats as they fill in numerals. First, an analog clock face is missing four numbers. Next, they write in the next four digits in a single-digit sequence....

For this math worksheet, students investigate telling time, elapsed time and word problems pertaining to time. Students also convert minutes to hours and hours to days. There are 40 problems on the 3 pages.

In this math learning exercise, students investigate the concept of paying interest on a loan. Students read 10 problems where they look at a picture of something they are going to buy at a certain price and interest rate. Students...

Pairs of geometry whizzes work together to determine which of three differently shaped cylinders will have the greatest volume. Pupils cut out the three rectangles embedded in the plan, and tape them together to form a cylinder. From...

Math whizzes utilize spreadsheets to examine linear modeling. They roll marbles down a ramp from three different heights and measure how far they roll. They use Excel to record their data and create a plot of their data.

Middle schoolers investigate the validity of da Vinci's proportion theory by recording human measurements on scatter plots. In groups of three, they record each other's height and wingspan to create a Powerpoint presentation, chart, or...

Mathematicians analyze the relationships between surface area and volume. They conduct Internet research, conduct various experiments, record the data in a spreadsheet, and graph the results and compare the rate of increase of surface...

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.

Middle and high schoolers participate in a seven-part lesson plan creating Escher-Esque tessellations. They demonstrate their knowledge of geometric transformations after viewing a PowerPoint presentation, conducting Internet research,...

Students explore careers in their community and compare the average salaries for men and women working in those careers. They explore a variety of careers available in their community through participating in this lesson.

Middle schoolers explore the concept of slope in numerous ways and start to look at simple linear equations. They describe the slope in a variety of ways such as the steepness of a line, developing a ratio, using graphs, using similar...

This exponential expression resource has each of the class members determine the value of given exponential expressions. They use their calculator to find the values and identify patterns. Besides writing the numbers exponentially, they...
