Playing with Quadperson

Compare the effects of relative and absolute changes on a picture. Watch what happens to a Quadperson (a drawing of a face made of quadrilaterals) if every line were made half as long or made a half-inch shorter.

Plot Plans and Silhouettes

Plot out a three-dimensional structure based on two-dimensional silhouettes. Look at the front and side view of figures and use a table to plot out the dimensions that mathematically represent the figures.

Polygon-Classification Game

Click all the polygons to see which Venn diagram circle they belong to. Then try to determine the correct labels for each of the circles.

Powerful Teaching and Learning

Read the description of each segment, then identify up to three elements of powerful teaching and learning best represented in the segment. Once you've identified the elements, explain your answers.

Practice Conversion Problems: Multiple Conversion Factors

If you don’t know the conversion factor between a metric and a British unit, use the conversion factors you do know even though this may require more than one conversion step. Practice conversion problems with multiple conversion factors.

Practice Conversion Problems: Two Conversion Factors

If you don’t know the conversion factor between a metric and British unit, use the factors you do know even though this may require more than one step. So if you need to go from meters to inches start with meters to feet and then convert feet to inches.

Problem: Cystic Fibrosis

Explore the concept of genetic inheritance. Learn how to calculate the probability that cystic fibrosis will be inherited using the Punnett square.

The Producer

Help a fictional producer balance a tight budget with his desire to make a successful, critically acclaimed film. Decide on personnel (screenwriter, director, cast), location, special effects and marketing while always keeping the budget in mind.

Puerto Rico

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

Put Your Money to Work

One way to be sure you'll have enough money to live comfortably when you retire is to put your money in a savings account where it will collect interest. Find out how simple and compound interest can help your money grow and calculate your own savings.

Quick Images

Stretch both your visualization and drawing muscles. View a shape for three seconds and then try to draw it from memory.

Quilts

Copy a quilt block made of 16 squares. Each block will have one of the four symmetry types: H, M, B, or S and you choose which you think it is.

Random Sampling

Sampling can produce measurement bias. See if you can personally select a sample that is representative of a particular population.

Reaction Time

You'll be challenged to test your reaction time under different conditions and then compare the results. You'll find out how processing in the brain changes reaction time under different conditions: being distracted, being presented with emotionally charged stimuli, or being faced with increasing complex tasks.

Reading Maps

Learn the visual language of maps (perspective, symbols and data) and see how mapping techniques have changed over time. Practice looking at maps as historical artifacts.

Reasoning About Fractions

Apply the reasoning and proof standard to a problem based on the Fraction Tracks game. Observe as students use a linear model as well as hands-on materials to solve the same problem.

The Rectangle Method

One approach for finding area is to surround the shape with a rectangle, determine the areas of the rectangle and subtract the pieces of the rectangle that are outside the original shape. Use this geoboard to create shapes and determine their areas.

Repeating Decimal Rings

The process of converting fractions to decimals can help clarify the relationship between the two. Investigate the repeating parts that emerge when you expand sevenths and 13ths fractions into decimals.

Report Your Sightings

Observe various migratory species (hummingbirds, butterflies, etc.) and report their sightings online. Share and review the sightings with other students/classrooms to track hemispheric migratory patterns.

Representations of an Infinite Series

What are some different ways to represent the sum of consecutive powers of 1/2; that is, 1/2 + 1/4 + 1/8 + 1/16 + ..., etc? Explore physical, numeric, geometric and symbolic representations and consider how you represent math in your own mind.
