Ptolemy's Theorem
Everyone's heard of Pythagoras, but who's Ptolemy? Learners test Ptolemy's Theorem using a specific cyclic quadrilateral and a ruler in the 22nd installment of a 23-part module. They then work through a proof of the theorem.
Curated OER
Brian's Pegboard II
Young scholars are able to assess a problem and use systematic methods to solve the problem. They also find out all the possible outcomes for a sequence of events using tree diagrams.

ndirect Measurement Technique: Using Trigonometric Ratios
Ninth graders find the height of an object that would be difficult or impossible to measure directly. They construct and use a Clinometer to measure the angle of elevation (or depression). Students create a sketch of the measurement...
Curated OER
Square and Triangular Numbers
Young scholars use equations to represent practical situations. They solve linear equations and quadratic equations. The use of problem solving strategies is also developed.
Curated OER
Exploring Similarity Using Scale Drawings
Learners explore scale factor as they create a scale drawing of a box, then determine the surface area and volume of the original and the scale drawing. The one page worksheet contains activities and procedures with four questions....

Congruent Triangles - Is This Enough Information?
Seventh graders examine congruence postulates and apply knowledge to triangles in the world around them.
Curated OER
Color Dots 2
Students develop simple observations. They observe bleeding of colored inks with water, to understand mixtures, and to make generalized inferences from their observations.
Curated OER
Follow Those Tracks
Students observe a picture containing patterns of animal tracks, infer what might have happened based upon the pattern of tracks, and write a story describing what might have happened.

Identifying Creatures
Students use a classification key from a provided worksheet to identify creatures. This task assesses student's abilities to interpret data, make decisions, identify, and classify.
Curated OER
Colored Dots 1
Learners observe that colored markers are a mixture of many different colors by performing a chromatography experiment. They make observations, record information, and make generalized inferences from their observations.
Curated OER
Packing Materials
Students observe the effects of water on four different packing materials to determine which ones are more soluble. They then decide which material would be a good packing material to use for the environment and which may be a bad...
Curated OER
Plastic Wrap
Students compare the price and quality of different kinds of plastic kitchen wraps and then rank them from best to worst. They take into account how well it comes out of the roll, if it seals well, it is tangles, how much weight it...
