Sampling Techniques
Sixth graders examine how to select samples and apply them to an experiment. In this sampling lesson plan, 6th graders use a bag of yellow and blue cubes to take a sample. They predict how many of each color there are the bag. They set...
Curated OER
Sin, Cos and Tangent
Students find the identity o sine, cosine and tangent. In this precalculus lesson, students solve and identify the different parts of a right triangle. They use the ratios of the Pythagorean Theorem to find the missing side or angle.
Curated OER
Scale Factor Area Perimeter
Mathematicians compare triangles at different scales. In this geometry lesson, young scholars calculate the area and perimeter of triangles. They use the Ti to make observation of the change that takes place as the triangles are dilated.
Curated OER
Scaling Figures Two
In this similar figures worksheet, students find the missing side of the larger figure when the smaller figure's sides are given. Students complete 4 problems.
Curated OER
Measuring a Mummy Case
Young scholars practice how to calculate volume using mummy cases. They measure using ancient Egyptian, U.S., and metric systems. They explore how to convert measurements into different systems, and discuss ratios.
Curated OER
Identify Similar Figures
Students explore the concept of similar figures. For this similar figures lesson, students develop the idea that similar figures are a different size but the same shape by comparing similar rectangles. Students use patty paper to trace...
Curated OER
Similar Triangles - Applied Problems
Students differentiate between similar and congruent triangles. For this geometry lesson, students identify the angles of triangles using the similarity theorem. They apply concepts of triangles to the real world.
Curated OER
Similarity and Congruence
Students explore the concept of similarity and congruence. In this similarity and congruence lesson, students identify and verify whether or not two figures are similar, congruent, or neither. Students use postulates and theorems such as...
Curated OER
Similarity and Congruence
Students explore the concept of similarity and congruence. In this similarity and congruence lesson, students cut out strips of paper and form a triangle. Students try to prove that their triangles are congruent using the SSS theorem of...
Curated OER
Prime Time Math
Seventh graders use educational software in order to practice lesson objectives. They define rate and ratio. Students solve distance problems given two variables. They also use a problem solving strategy that can be defended in its usage.
Curated OER
Body Building
Pupils determine whether ancient Egyptian drawing was proportional and in perspective by comparing ancient Egyptian drawings, a mummy's x-ray, and contemporary photographs of people.
Curated OER
How Many Bears in the Forest?
Third graders model the tag and recapture of bears and use proportions to estimate the population of the bears in their forest. This is a statistical sampling method used by scientists and naturalists to determine population numbers.
Curated OER
Converting fraactions and percents
Sixth graders practice the conversion of percents and fractions. They focus on the fact of both fractions and percents are part of a whole. In the independent practice the students also work with solving proportions.
Curated OER
Wings and Othe Things
Students work in groups that are engaged in different activities at different times. They watch the video "Madagascar" and collect data pertaining to the Fish Eagle's arm spam. They work together to perform mathematical computations...
