Modeling Using Similarity
How do you find the lengths of items that cannot be directly measured? The 13th installment in a series of 16 has pupils use the similarity content learned in an earlier resource to solve real-world problems. Class members determine...
Curated OER
Extraordinary Extrapolation
Students study how scientists have estimated the maximum height to which trees can grow, and assess the reliability of interpolation and extrapolation techniques by making predictions with particular data sets and analyzing accuracy of...
Curated OER
Prime Factorization
Sixth graders participate in a lesson that focuses on the concept of finding the prime factorization of a number. They write the answer using exponential notation. Students play a game of Bingo to keep engaged during the lesson.
Curated OER
Prime Factorization
Students work with prime numbers. In this prime factorization lesson, students review writing numbers in their prime factorization form and solve multiple problems.
Curated OER
The Fair Factor
Students participate in playing many games to determine if they are fair or not. They create their own game that is fair to play with their classmates.
Curated OER
What Are You - Prime or Composite
Students explore the concept of prime factorization. In this prime factorization activity, students participate in an activity where they find the prime factorization and greatest common factor of a number derived from their name....

Trees For Trout!
Fourth graders determine the impact of native forests, local clearcuts and local clearcuts and local reforestation projects on the survivablity of Rainbow Trout in their area. They record and document the stages of the trout throughout...
Curated OER
Carrying Capacity of Ecosystems
Students define population and carrying. In this algebra lesson, students explore exponential growth and decay based on animals and things that grow or decrease exponentially. They graph their findings and discuss their results as they...
Curated OER
The Generation of Fractions
Young scholars explore the process of reducing fractions to simplest form by using a multiples grid. In this simplest form lesson, students pull different fractions out of a bag and then consult their grid to discover all the multiples...
Curated OER
How Healthy is the Wetland?
Students explore wetlands. In this ecology lesson plan, students visit a wetland site and collect data about the wetland functions. Students record their results and use the data recorded to rate the wetland site on its function.
Curated OER
Shape and Space: Transformations
Students explore transformations. In this mathematical transformations lesson, students define quadrilaterals, convert centimeters to meters, and complete a transformations worksheet.
Curated OER
Similar Triangles - Applied Problems
Students differentiate between similar and congruent triangles. In this geometry lesson, students identify the angles of triangles using the similarity theorem. They apply concepts of triangles to the real world.
Curated OER
Intro To Probability
Students investigate the concepts related to the practice of using probability. They review the use of mean, median, and mode within the context of previous instruction. Students predict outcomes and calculate them in small groups. The...
Curated OER
Toothpicks and Timber
Students problem-solve how to log five acres. Working in pairs, they construct models of logging sites before and after the trees are harvested. they paint their models and include other environmental details.
Curated OER
Maximizing Lumber Cuts
Students examine how lumber companies use each tree to the fullest extent. They practice using a saw blade in which they cut a piece of wood in different configurations to see which cut can waste the least.
Curated OER
Prairie Adaptations
Twelfth graders consider the survival of prairie plants. They examine how some tallgrass prairie species are adapted to the conditions of their ecosystem. They make a prediction of how a species might change given new conditions.
Curated OER
Similar Figures
In this geometry worksheet students explore similar polygons and determine measure of missing sides and angles. Students use indirect measurement with similar triangles and determine the area and volume of similar figures. The seven page...
