Eye From the Sky
Students are introduced to the concept of aerial perspective and scale. Students will use satellite technology to view their neighborhoods and sketch the area surrounding their schools. They will take part in a neighborhood walk to view...
Curated OER
How far is a km?
Young scholars explore the size of a kilometer and the time it takes to cover this distance. They develop a concept of a km. They measure a distance of 1 km and the time taken to cover it.

Speed Is the Key
Students design and build a model downhill ski course that proves to be the fastest course at the Finish Line. They apply what they explore angles, slope, speed, and surface conditions to find the fastest course in the US.
Curated OER
Paper Pool
Students analyze the measurements of rectangles. In this analysis activity, students will investigate patterns by looking at ratios. Students will also hypothesize the probability of a ball going into a certain pocket when playing pool....
Curated OER
Signal Flags
Pupils examine the use of signal flags on vessels. They use measurements and symmetry to create their very own signal flag. Students work together and as individuals to solve problems and express their ideas.
Curated OER
Trigonometry
Eighth graders practice calculating the unknown length of a right angle triangle. They also examine the pythogoram theory in groups. They help each other work through the problems.

Introducing the Coordinate Plane
Fifth graders practice using estimation. In this estimation lesson, 5th graders add, subtract, multiple, and divide using whole numbers, fractions, and decimals. Students decide upon instances when estimation is more appropriate than...
Curated OER
Quilt Squared
Students study West Virginia quilts. In this mathematics lesson, students use symmetry, geometric shapes, and patterns to create their own quilt square.
Curated OER
Altitude Tracking
Students construct simple altitude tracking devices for determining the altitude a rocket reaches in its flight. They estimate the altitude a rocket achieves during flight.
Curated OER
Transformations and Rotations
Students define and identify transformation and rotation. In this geometry activity, students define rotations as congruence or isometry. They find the coordinates of an image and pre-image.
Curated OER
Probability and Geometry
Students explore the ways Geometry can help solve probability problems. Students describe platonic solids and practice calculating probability using an online resource. They construct dice with various numbers of sides to demonstrate...
Curated OER
The Tangent Ratio
Students calculate the tangent ratio given a right triangle. In this trigonometry lesson, students use a right triangle and the Pythagorean Theorem to solve problems.
Curated OER
Trigometric Ratios
This lesson requires a worksheet that is not connected. It is integral to the lesson.
Curated OER
Similarity and Congruence
Students determine that two figures are similar or congruent by
investigating figures that are similar and figures that are congruent. They prove that two figures are similar or congruent by using definitions,
postulates, and theorems.
Curated OER
Transformations: Translations
High schoolers perform transformations and translations using polygons. In this geometry lesson, students perform transformations on a coordinate plane. They identify the image and pre-image of each figure.
Curated OER
Making a Circle Graph of a Sample Budget
Students examine a sample budget and categorize the entries as a group. Then in small groups they convert budget category totals to percents and degrees to make a circle graph related to a sample budget.
Curated OER
Surface Area of Prisms
Students compute surface area and volume of prisms. In this surface area lesson, students find the surface area and volume of rectangular and triangular prisms. Independently, students use their computers to determine the volume,...
Curated OER
Surface Area and Volume
Students are introduced to the notion of surface area and volume, learn the terminology used with surface area and volume and have experimented with the surface area and volume of different prisms.
Curated OER
Navigating by the Numbers
Students observe how math is important in navigation and engineering. They study how surveyors use math and science to calcute, count, measure, label, and indicate distances on a map. They estimate specific distances.

REAL LIFE REAL WORLD Activity - Surveyor
Learners investigate surveying in this secondary mathematics lesson. They will explore a real world application of geometry and trigonometry as they create a plot plan using a geometry utility and calculate the area of the land parcel.
Curated OER
Graphing
Learners collect data to create different types of graphs-line, pie, and bar graphs. They use StarOffice 6.0 to create graphs.
Curated OER
Scatter Plots
Seventh graders investigate how to make and set up a scatter plot. In this statistics lesson, 7th graders collect data and plot it. They analyze their data and discuss their results.
