Curated OER
Determine the Measure of an Angle of a Right Triangle.
In this geometry worksheet, students solve word problems by finding the values of missing angles and missing sides of triangles. They review their trigonometric properties of a right triangle. There are 9 problems with an answer key.
Curated OER
Mini-Metric Olympics
Students participate in a Mini-Olympics with measurements. In this measurement lesson, students throw items and predict how far they will go. They measure the actual distance and find the difference between that and their estimate.
Curated OER
Taking Estimation and Measurement Outside
Eighth graders gain a better understanding of visual distances and estimation. They actively practice using metric measurement and conversion. Students practice cooperative exploring and team building.
Curated OER
Introduction to Measures of Central Tendency and Variability
Students calculate the mean, median, mode, range, and interquartile range for a set of data. They create a box and whisker plot using paper, pencil and technology.
