Students see how division is used to help solve probability problems. They use tables as data structures where they are used to count outcomes and to compute probabilities. Students use games to help solve probability problems.

Pupils explore percent increases and decreases. They calculate the percent increase and decrease. Students use math to solve problems and communicate. They apply the given formula for percent increase/decrease.

Students observe models of fractional parts. After writing the definitions of percent, part and whole, students use the calculators and computers to solve problems. Individually, they complete assigned problems where the convert the...

Students, after completing a warm up exercise on one proportion word problem, distinguish between functions and non-functions. They identify domain and range on a function as well as recognize and implement function notation. They solve...

Students investigate speed, time and distance. In this algebra lesson plan, students utilize their knowledge of linear equations to solve problems related to time, speed and distance. This assignment is hands on using two toy race cars.

In this inverse variation worksheet, students solve twelve inverse variation problems.  Five of these problems are multiple choice and seven are free-response problems.  this worksheet is designed are preparation for the Math...

In this math worksheet, students describe a step by step method to solve rate problems. Then they state the time derivatives of different quantities.

Explore rational numbers with the young mathematicians in your class. They will investigate decimals, fractions, and percents before ordering and comparing rational numbers. This multi-day unit includes differentiation activities and...

Students read an explanation from the NASA Web-based "textbook", The Beginner's Guide to Aerodynamics, then use the information in combination with data from other Web sites to solve single variable equations for distance (range), time,...

Pupils build a working definition of regular fractal, look carefully at the concepts of dimension and scale, and are introduced to logarithms. They solve simple exponential equations for the exponent both by trial and error and using logs.

Middle schoolers build a working definition of a regular fractal, they measure the concepts of dimensions and scale, they explore the concept of a logarithm and they attempt to solve simple exponential equations for the exponent both by...

Third graders model the tag and recapture of bears and use proportions to estimate the population of the bears in their forest. This is a statistical sampling method used by scientists and naturalists to determine population numbers.

Learners determine the size of the population at a given time. They calculate the time at which the population will be a given number. They observe how the population grows at the rate that is directly proportional to the number of...

Students examine population growth and collect data. In this statistics instructional activity, students create a scatter plot to represent the different species found in the water and are being harvested. They graph their data and draw...

Young scholars calculate the distance they will travel. In this geometry lesson, students use the TI and CBL system to make calculation of a certain path. They explore geography by calculating distances between different areas as it...

Middle schoolers find the cost of an outfit. In this percentages lesson, students look at ads, pick out an outfit, and find the sale price. They create a commercial and complete 4 included worksheets. 

Over the course of three class periods, middle schoolers design an experiment to provide learner input to administration about which rock band to invite to play at school. They practice several random sampling exercises, all well...

Strive to think outside of the quadrilateral parallelogram. Worksheet includes two problems applying prior knowledge of area and perimeter to parallelograms and trapezoids. The focus is on finding and utilizing the proper formula and...

Let's paint the town equal parts yellow and violet, or simply brown. Pupils calculate the amount of blue and red paint needed to make six quarts of brown paint. Individuals then explain how they determined the percentage of the brown...

Examine food labels to determine percentage of fat and sugar to total calories with middle schoolers. Daily nutritional guidelines are discussed and learners will decide how well their foods fit into a healthy diet. In the provided...

See how design and geometry go hand in hand. The activity asks learners to use geometry to design a backyard garden given dimensions of each feature. Scholars work with ratios and scale to develop an accurate scale drawing that includes...

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...

Find that slope! This video does an excellent job of demonstrating how to use the slope formula to find the slope of a line using two points. The instructor first reviews the definition of slope of a line, then works three problems using...

To take the longest path, go around—or was that go over? Class members measure scale drawings of a cylindrical vase to find the height and diameter. They calculate the actual height and circumference and determine which is larger.
