Grab some marbles from a bag. The applet simulates drawing marbles from a bag. Pupils determine the number of four colors of marbles in a bag and how many marbles to draw. Using information on whether order matters in the draw and if...

Build upon and stack up data to get the complete picture. Using the applet, pupils build bar graphs. As the bar graph builds, the interactive graphically displays the mean, median, and mode. Learners finish by exploring the changes in...

Take a look at data from a statistical lens. An interactive allows pupils to enter data set, labeling the data including the units used. Manipulating the applet, learners select the statistics to calculate that include total, mean,...

Liken a cell and its organelles to a tiny person and its organs. After gathering information on cell structures and their functions, small groups collaborate to come up with an analogy of their own. They produce a collage describing the...

Fifth graders build increasingly larger squares and triangles using pattern blocks. They record the growth patterns on a chart and look for corresponding numerical patterns. Students describe the patterns they find and use them to...

Students estimate the distance of student's broad jumps. This activity can take place in the block center with a small group of students. They are explained that they are going to jump from a starting point (marked with the masking...

Stories from "The Great Lakes Mariner" provide pupils with an opportunity to practice their synopsis-writing skills. The tabloid, which focuses on the Great Lakes region, is filled with stories written by sea captains, that are filled...

Engage scholars in a ratio lesson that employs real-world scenarios. Learners will compare the length and width of pictures and use a table to identify ratio patterns. They watch "Math Can Take You Places" and discuss jobs that use math...

Consider complex numbers, roots, and quadratic equations. Use the discriminate as a way to determine the nature of a quadratic's roots. Then discuss the similarities and differences between quadratics with two, one, or no real roots....

Abracadabra! Letters can be used in math to represent numbers with the operations of addition, subtraction, multiplication, and division to solve problems! Math magicians will participate in an activity that uses a calculator and a bag...

High School geometers verify through experimentation certain properties about dilations. This multi-step problem challenges them to construct examples of dilations to verify specific facts, the final step provides an opportunity to more...

Elementary ecologists examine trophic relationships using a coral reef food pyramid as an example. They play a game applying math skills that ultimately demonstrate the important role of the ever-scary top predator, the shark. This is a...

Here is an introduction to solving simultaneous linear equations. Start by drawing a line through two points. Create a second line which goes through the intersecting point. Background knowledge of how to find the equation of a line and...

Do big bodies make big brains? Let your learners decide whether there is an association between body weight and brain weight by putting the data from different animals into a scatterplot. They can remove any outliers and then make a line...

In this second of three activities, energy engineers plan and create a hydropower dam as they learn how hydroelectric power plants generate electricity. A hydropower puzzle is also included, which can be worked on by teams that finish...

Your young landscapers do concentration calculations in this problem dealing with mixing fertilizer. Learners use and analyze rational expressions within this context.

Scholars gain an insight into the relative size of planets and distance between inner and outer planets with the help of informational text, a data table, and a series of four questions.  

Examine ratio and scale through coordinate geometry. Scholars use two diagrams of different scale to calculate perimeter and area. Then, individuals use the perimeters and areas to find ratios.

Develop a new measure of the properties of an object. Scholars develop a definition and formula to measure the bumpy-ness of an object. They utilize their formulas to find the property for several spherical objects.

How do robots assist ocean explorers in collecting data and images? The final installment in a five-part series has science scholars examine underwater images collected by robots and identify the organisms shown. Groups then calculate...

Adjust the overlap to compare probabilities. Using sliders, learners adjust the shape of two Gaussian curves. The interactive calculates the area of the left tail for one curve and the right tail for the other. Pupils set the interactive...

A change in a parameter can end in overpopulation. The resources gives pupils the opportunity to control the parameters of rabbits and wolves in a natural setting. Using the set parameters, the simulation runs and displays the population...

Control the spread of a contagious disease. An applet allows pupils to run a simulation on the spread of a disease. Rules govern how the disease is spread and the length of time it takes to recover. Learners view the spread visually and...
