Your young basketball players will build a table and develop a general formula for a decaying exponential scenario involving the rebound distance of a bouncing ball. Using a CBR and graphing calculator can make this even more hands-on...

Does the number of calories you eat affect the total time you sleep? Young mathematicians tackle this question by collecting their own data and making comparisons between others in the class through building scatter plots and regression...

Bring the sun to your class! Young scholars analyze actual solar wind data in the second lesson plan of a five-part series. Their analysis includes speed, temperature, and density data.

Learners explore how changing an angle in a triangle changes the ratio of the sides. They also explore how changing the sides can make changes to an angle in a triangle. Finally, they determine how two different pairs of sides, in the...

Learners explore interaction between mathematics, science, and technology as they look at process of researching, developing, testing, and evaluating airplane design. They calculate glide ratio for model paper airplane by using data...

Learners investigate the slope of a cubic function. They find the tangent line of the cubic function at point P, and discuss the relationship between point P and point Q, the point the tangent line intersects the cubic function. ...

This lesson requires a worksheet that is not connected. It is integral to the lesson.

Eighth graders explain the relationship between the position of the sun, a city's latitude and shadow length. Ratio's, geometry, and algebra are used to determine the shadow lengths and building heights. A sun angle (altitude) charts to...

Young ratio masters calculate and cut a frame (out of poster board) to accurately create an even frame around a picture of themselves. The frame needs to be proportional to the picture with constraints determined by the instructor. 

Sixth graders pariticipate in a lesson that focuses on the finding of a ratio and using it to set up a proportion in realtionship to creating a scale drawing. This is done using given problems. It would be valuable for students to have...

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...

Learners find common ratios of geometric sequences on a spreadsheet. Using this data, they create scatter plots of the sequences to determine how each curve is related to the value of the common ratio. They will consider whether series...

Learners solve problems using trigonometric functions, specifically a problem about a tree stand. Pupils try to maximize the distance of hunting sight given certain restrictions. They use the Pythagorean Theorem, sine, cosine, and...

Young mathematicians draw and label right triangles using Cabri Jr. technology. They create other special right triangles and identify the length of the hypotenuse and each leg. High schoolers explore the ratios to determine how the...

Far out — plan a trip to space! Aspiring mathematicians steer a space vehicle through an asteroid field, calculate currency exchanges to buy provisions, and determine placement of charges to blow up asteroids. Along the way, they learn...

What type of quadrilateral is that? Discover the difference between the types of quadrilaterals. Small groups investigate types of quadrilaterals using geometry software to find their properties. To keep track of the different...

How do scientists identify which elements originate from meteorites? Scholars learn about a sample of material found in a remote location, analyzing the sample to determine if it might be from Earth or not. They study elements, isotopes,...

Student sinvestigate the area and perimeter of polygons. They differentiate between similar and congruent polygons.. They identify the ratio and proportions of the sides and angles of polygons.

Young scholars explore ratios and their relationships to fractions. They explain the process of identifying ratios and describe their comparison. Students write ratios as fractions and by using colons. They convert the ratios to...

Eighth graders investigate the basic concepts of probability. In this probability lesson, 8th graders learn the associated probability. They work with spinners, colored cubes in a bag, flip coins, and choose colored candies while they...

Seventh graders participate in a instructional activity that focuses on having them solve different proportions. The instructional activity includes an example that the teacher can work from in order to deliver direct instruction.

Seventh graders construct a three dimensional model of a constellation. In this constellation lesson, 7th graders make a blueprint for a scale model of the constellation and create their models. They present their models to the class.

Given a box of certain dimensions, young mathematicians must determine if a box that is twice as big, actually holds twice as much. This is a brain-teaser of a problem. The worksheet provides a handy table that has learners calculate the...

Here is a simple and clever activity which illustrates the concept of mathematical proportion and size quite effectively. In it, two pupils hold baseball bats: one is a regulation-size bat, the other is a miniature souvenir bat. The...
