Made from Dots

Notice how magazines print photos using dots made up of percentages of only three colors and black. Try your hand at using percentages of cyan, magenta and yellow to match the magazine color displayed.

Making a Line Plot

Practice creating a line plot. Use raisin counts for 17 boxes of raisins to graph the distribution of raisins per box.

Making a Stem and Leaf Plot

A line plot may not be a useful graph for investigating variation so we must come up with a new representation based on groups of data. Construct a stem and leaf plot from a set of 26 data values.

Making a Tree Diagram

A tree diagram is a helpful tool for determining theoretical or mathematical probabilities. Toss a coin and watch as branches represent a toss of either head or tails.

Making Connections in Your Teaching

Connect teaching goals with strategies that enhance learning. Select teaching goals, review the tips provided, then brainstorm and list strategies you would use to help students make connections. Compare your answers to other teachers' answers.

Making Sense of Mathematics Text

In this activity, explore different protocols for making sense of mathematical text that meet the needs of your students.

MapMaker - U.S. History Interactive Maps

The maps provide an overview of key themes in U.S. history: the Civil Rights Movement, Women's Suffrage, the Mexican-American War, Westward Expansion, the Great Migration, the Great Depression, Early Explorers, Labor Movements, Native American Removal and Resettlement, and Immigration. Educators and students can customize maps by adding bookmarks, markers, and information and save them as their own.

Mass Units and Their Symbols

Study the names and abbreviations of mass units in both the metric and British systems. Then play a game to see how well you remember them.

Measuring Ant Tunnels

Students have used three non-standard measuring tools to estimate the length of an ant tunnel. Think about the problem-solving aspect of this activity as you compare their estimates.

Measuring Learning

You will use contextual cueing to measure your ability for implicit spatial learning. Your task is simple: repeatedly search for an object hidden in a set of photos. The program will then give you information you can use to gauge your implicit learning.

Measuring Short-Term Recall

Compare your recall of a list of non-words versus a list of words in timed sessions. Consider whether or not there might be bias in your experimental design.

Measuring Steepness

Does the ratio of height to distance and the angle of elevation change as you move a ladder? Identify any patterns that exist between the height-to-distance ratios and the angles.

The Median

Determine the median of eleven noodles. Consider what you would or would not be able to tell about the other noodles if you could only see the median noodle.

Medieval Hats

Hats were an important part of medieval garb in the Middle Ages. Look at pictures of five medieval hats and try to determine which of the people listed wore which of the hats.

Medieval M.D.

You are a doctor in the Middle Ages with three patients to cure. Read about their symptoms and decide what medieval treatment to prescribe.

Meeting The Needs of Students

Generate integrated teaching activities that meet student needs, e.g. creativity, social interaction, etc.

Melting Rocks

Turning solid rock into liquid magma involves changing its temperature, pressure and water content. Try your hand at melting rock to create magma.


Compare the ticking of a metronome to a sine wave. Use interactive metronomes to explore the phenomenon of spontaneous synchronization.


Practice some of the vocabulary and grammar covered in the Mexico episodes of Destinos.

The Midline Cut

You can cut geometric figures into pieces that you can rearrange to form different geometric figures. Show how the midline cut of any triangle can be used to form a parallelogram. View non-Flash version.
