Learn about the different types of characters in Cinderella, and determine which traits belong to the hero and villain.


Learn about climax and identify the event that signals the climax in the story Cinderella.

Colored Shadows

Manipulate dual shadows and learn why different types of shadows are cast.

Comparing Fractions: Bubble Gum Blowing Contest

Explore equivalent fractions, and decide which of two classrooms is better at blowing bubble gum.

Comparing Representations

Statistical analysis allows us to organize data in different ways to draw out potential patterns in the variation. Review and compare data represented in a bar graph and accompanying tables depicting relative and cumulative frequency.

Comparing Slopes

Control the slope of lines passing through the origin (0, 0). Keep track of what changes when the slope becomes positive or negative, and when slope is larger or smaller than 1.


Learn about a story's conflict, and then identify the character who is describing the conflict of "Cinderella."

Congruent Shapes

Find shapes that are congruent. Verify that they are congruent by making rotations, slides, and reflections.

Connecting Themes and Disciplines

Connect themes and content to teaching strategies and activities. Practice developing lesson ideas by listing new concepts you would teach and activities you would use to teach them.

Constant Area

Do figures with the same area have the same perimeter? Arrange and rearrange 12 square tiles on a grid, and then measure the perimeter of each shape you create.

Constructing Quadrilaterals

Use a "linkage strip" to to build quadrilaterals with different sets of lengths. Once you build a quadrilateral, see if you can deform it into a different quadrilateral with the same side lengths.

Constructing Triangles

Use a "linkage strip" to build triangles with different side lengths. When you build a triangle, see if you can deform it into a different triangle while keeping the side lengths the same.

Counting Raisins

Count the number of raisins in seventeen half-ounce boxes of raisins. Then come up with a solution to determine how many raisins are in Brand X's or Brand Y's box of raisins.

Counting Stairs

Build staircases out of square blocks. Look for patterns and come up with a rule or formula to predict the number of blocks in any staircase.

Creating a Line Plot

Watch as a physical stack of coins is added as a series of dots to a line plot.

Cylinders, Cones, and Spheres

Is there a relationship between the volume of a sphere and the volume of a cylinder of equal diameter and height? What about the volume of the sphere and the cone?

Decorative Boxes

Students need to cover 24 boxes with decorative paper. Observe as they use geometry and measurement to determine the area of one box in order to estimate the total amount of paper needed.

Design a Schedule

Map out a week-long schedule with time allotments so that you have at least 90 minutes of reading and writing each day.

Determining Rotation Symmetry

Explore properties of rotation symmetry. Determine the angle of rotation for different images.

The Distance Formula

Plot points on a graph. Use the Pythagorean theorem to calculate the distance between them.
