PRE ALGEBRA
Eighth graders find missing angles of triangles, quadrilaterals and angles formed by parallel lines cut by a transversal. They use area formulas to find the area of a figure; find the complement and supplement of a given angle; and know...
Curated OER
Distance Formula
Students watch teacher demonstration of distance formula, view non-collinear cities on maps, plot points on coordinate plane, evaluate square roots, compute distance between two points, and use Heron's formula to find area of triangles.
Curated OER
Reflection of Light and Mirrors
Students address common misconceptions concerning reflection, light and mirrors. They investigate light reflection in mirrors and determine how light is transferred to the eye. In addition, they make predictions and then test them...
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
Polygon Sum Conjecture
In this geometry instructional activity, 10th graders identify the missing angles using the polygons sum conjecture. They measure exterior and interior angles using their angle theorems. There are 63 problems.
Curated OER
Properties of the Ocean: Change
Students research and create a visual presentation on the seasonal salinity of the Earth's oceans. They apply the research in a simulation of a lab disaster in which they must relabel ocean samples.
Curated OER
Great Graphing
Students collect data, use a computer spreadsheet program to create various graphs, and compare the graphs. They state the findings of each graph in writing and decide which graph type best represents the data.
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
Paying for Crime
Learners participate in activties examining ratios and proportions. They use graphs to interpret data showing the government's budget for prisons. They present what they have learned to the class.
Curated OER
Glacial Striation Investigation
Students operate a GPS unit to investigate the direction of glacier movement. They describe the motion of glacier movement by interpreting a graph. Students explain how scientists use glacier striations to determine glacier movement.
Curated OER
An Archaeological Adventure in Athens
Students review map skills and practice finding locations on a map. In groups, they create maps with mystery locations identified by hidden stick-on magnets. Other groups attempt to find the mystery locations and then check their work...
Curated OER
Stars and Constellations
Ninth graders investigate how ancient cultures viewed their world in terms of astronomy. They read and discuss an informational handout, construct an astrolabe, and locate stars and constellations using star charts.
Curated OER
Public Land
Students examine the needs of their community for public space and determine the solutions to math problems related to planning landscape designs. They read and discuss an article from the New York Times, create their own designs for a...
Curated OER
Building Blocks of Geometry
In this geometry learning exercise, students answer questions about midpoints, distance, lines and segments. They are given different shapes and asked to calculate the angles, and sides of polygons.
Curated OER
Measurement via Triangulation
Students utilize triangulation techniques to determine altitudes of objects. An altitude locator is constructed and used to determine the height of a building or a tree. Tangent tables and formulas provide the ratio for the formula to...
Curated OER
Sextant Measurements
Students create a sextant. Using their sextant, students measure the height of tall objects. Students explore how sailors used sextants to identify their location on the ocean. They research how sextants are created.
Curated OER
Transversal and Angles
Tenth graders identify angles formed by parallel lines and a transversal. Using meter sticks and bolts, they perform hands-on activities to demonstrate the properties of parallel lines and congruent angles. They color code diagrams to...
Curated OER
What Is Your Angle?
Students explore the concept of angles by interacting with numerous types of measurements. They create index cards with different angles. Then they pass the cards around to other students for comparison and measurement. They practice the...
