Areas of Polygons
Students calculate the are of regular polygons. In this geometry lesson, students create polygons on the computer and move it around to create different shapes. They explore the area of different polygons and how they inter-relate.
Curated OER
Exploring Angle/Pair Relationships
Students find missing angles and sides of triangles. In this geometry lesson plan, students create intersecting lines to measure angles. They use Cabri Software to create virtual angles.
Curated OER
Exploring Geometric Mean
Students solve problems using geometric means. In this geometry lesson plan, students create altitudes in right triangles. They use Cabri software to move the triangle around and observe different sides and angles.
Curated OER
Exploring Geometric Mean
Student identify the solution using geometric mean. In this geometry lesson, students create right triangles where the altitude of the triangle is the side containing the right angle. They modify shapes using Cabri software and observe...
Curated OER
The Trappings of Trapezoids
Students define trapezoids and their shapes. In this geometry lesson, students calculate the area of a trapezoid and a parallelogram. They use Cabri software to make investigations.
Curated OER
LRO's First Image of Mare Nubium
In this scale image worksheet, students use an image taken by the LRO satellite of Mare Nubium to determine the scale of the image, the diameter of the smallest crater and a comparison scale drawing of a house.
Curated OER
Exponential Functions and the Natural Logarithm
Students solve exponential and log functions. In this algebra instructional activity, students graph natural log and logarithmic functions. They compare and contrast between logs and the exponential graphs.
Curated OER
Comparing Data
Eighth graders create a survey, gather data and describe the data using measures of central tendency (mean, median and mode) and spread (range, quartiles, and interquartile range). Students use these measures to interpret, compare and...
