Congruent Triangles Postulates
Students discover three lettered postulates that prove triangles congruent.
Curated OER
Translating Transformations in Geometry
Students create an image using given coordinates and evaluate how the coordinates change when a slide or rotation takes place.
Curated OER
Getting Familiar with Fractals
Students use the Internet to answer lab questions about fractals, and then construct fractals using the initial stage and iteration rule. They complete tables and generate rules for the "nth" term and create their own fractals.
Curated OER
Technology Literacy Challenge Grant Learning Unit
First graders explore counting and classification. They sort leaves, create graphs, write sentences for the data in the graphs, develop graphs for shapes, favorite animals, birthdays, and participate in a die prediction game.
Curated OER
Putting Your Best Foot Forward
Third graders measure their feet and their parents' feet, record data on computer-generated graphs, and calculate and record mean, median, and mode.
Curated OER
Introduction to Polynomials
Young scholars analyze the graphs of polynomial functions, examine vocabulary associated with polynomials, and determine the maximum number of real roots possible for a polynomial
Curated OER
Car Maze competition
Young scholars use graphs to calibrate an RCX car. They must then program the car to traverse a maze using their calibrations
Curated OER
The Odyssey: A Deeper Appreciation
Students read "The Odyssey" and identify the ways it relates to their own lives. As a class, they also examine the history of the story and identify the various Greek gods and goddesses. In groups, they focus on the geography of the...
Curated OER
Investigating Scale Factors with the Geometer's Sketchpad
Students use Geometer's Sketchpad to examine the scale factor when in is applied to the length of a figure's sides. They look at how the scale factor affects the side lengths, perimeter, and area of the figure that result. They work with...
Curated OER
Drawing Lines of Symmetry
Third graders explore the concept of symmetry using geometric shapes, capital letters and various other shapes. They fold shapes to show symmetry, draw lines of symmetry and create symmetrical designs.
Curated OER
Choosing the Best Graph
Eighth graders produce and examine two sets of data and create what they believe to be the most appropriate graphs to represent these sets of data. After completing the pre-assessment, they discuss reasons for using each type of graph...
Curated OER
Sun and Temperatures
Students consider the relationship of temperature to environmental conditions and then apply their knowledge to a practical event. The task assesses students' knowledge and application of that knowledge to an additional situation.
Curated OER
Rubber Band
Eighth graders investigate what would happen to the length of a rubber band as more and more rings were hung on it. They base their explanation on what they observed, and as they develop cognitive skills, they should be able to...
Curated OER
Ocean Botttom Profile
Students interpret a graph of ocean depths and topographic features. This task assesses students' abilities to interpret figures, organize and represent data, apply knowledge of scale to a profile, and apply theoretical knowledge.
Curated OER
From Probability to Combinatorics and Number Theory
Students see how division is used to help solve probability problems. They use tables as data structures where they are used to count outcomes and to compute probabilities. Students use games to help solve probability problems.
Curated OER
Replacement and Probability
Students explore sampling with and without replacement. They explore the effects on the probability of drawing a desired object. Students examine probability and the difference between sampling with and without replacement.
Curated OER
Expected Value
Students discuss what expected value is, they are introduced to the concept of varyting payoffs. Students use a computer simulation of a "real world" example where expected value is used.
Curated OER
Patterns and Sequences
Ninth graders examine sequential number patterns and the Fibonacci sequence. Given number patterns, they determine the next number in a sequence. Students develop their own number patterns and exchange them with another to be solved.
Curated OER
Exploring Arrangements of 2, 3, 4, and 5 Cubes
Students use problem solving skills to create various models of tricubes, tetracubes, and pentacubes. They classify the cubes into various groupings and identify them as mirror images, regular arrangements, and irregular arrangements....
Curated OER
Similar Triangles
Ninth graders find the height of every day objects using techniques learned through postulates that allow triangles in a problem to be similar. They calculate the length of a missing side and solve proportions.
