Leaping Lemurs! How far can you jump?
Young scholars watch a segment of the PBS video which show the lemurs' ability to jump. In pairs, students collect measurement data involving each other's length of a standard step, a standing broad jump, and a long jump. They record...
Curated OER
Graph Both Crusts
Fourth graders calculate the angles and construct a pie graph of the percentages of the elements in the continental and oceanic crusts. Then they analyze the results. They can be assigned the task of researching the percentages.
Curated OER
Got Milk?
Students measure the angles of a milk carton. They identify and label acute, right, and obtuse angles. Using appropriate tools, students determine the volume of a cube or a rectangular prism. Students complete worksheets to...
Curated OER
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
The Distance to an Unapproachable Point
Students use geometry or trigonometry to measure the distance of a far off point. They verify their measurements using a tape measure to check their work.
Curated OER
Math: Arcs and Chords
Students draw diagrams demonstrating how it is possible to two central angles to be congruent and their minor arcs are not congruent. In groups, they illustrate theorems with their constructed circles, create diameters of circles that...
Curated OER
Volcanoes: Piles of Fire
Students investigate how particle size affects the angle of a volcano's slope.
Curated OER
For Better or Worse: Cultural Exchange
Students participate in a cultural exchange program with a Native American school in Winnebago, Nebraska. They conduct research on a variety of Native American tribes, prepare a presentation that represents the culture of their school...
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...
Curated OER
Laws of Reflection
Students experiment with mirrors to explore the Laws of Reflection. In this experimental lesson students develop their own experiments and follow a list of assigned steps then report what happens in their activity.
Mathematics Vision Project
Module 6: Congruence, Construction, and Proof
Trace the links between a variety of math concepts in this far-reaching unit. Ideas that seem very different on the outset (like the distance formula and rigid transformations) come together in very natural and logical ways. This...
K12 Reader
Punctuating Appositives
Where do the commas go? Kids rewrite a series of sentences using commas to set off the appositives in each sentence.
Curated OER
Vector Lab
Here is a math lab that helps young mathematicians understand the real-life meaning for vector addition. By building a model using spring scales and washers as weight, and then calculating the vector addition using two different methods,...
Curated OER
The Tipping Point
Students rewrite word problems and solve using math. In this word problem lesson, students gather data and observe the data. They relate this process to the scientific method and math. They review their data to be able to answer...
Curated OER
Quilt Squared
Students study West Virginia quilts. In this mathematics activity, students use symmetry, geometric shapes, and patterns to create their own quilt square.
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
Graphing
Students collect data to create different types of graphs-line, pie, and bar graphs. They use StarOffice 6.0 to create graphs.
University of Texas
Free-Body Diagram
Preparing for an AP test is about more than bubble sheets and memorization. The two activities in this resource require a direct application of skills learned throughout an AP Physics course.
Curated OER
Volume of Solid Figures
Learners calculate volume using the correct formula and the correct unit. They explore different prisms, spheres, cubes, and cones as they calculate volume and relate it to depths in oceans.
Curated OER
The Luxor Hotel Contract
High schoolers determine the surface area of the Luxor Hotel, using the square feet of the base, volume, and the volume formula. They create a scale model of the triangular/pyramid shaped hotel.
Curated OER
Congruent and Similar Figures: Reteach
In this congruent and similar figures activity, students review three steps to help them determine if figures are congruent, similar, or neither. Students then study the pairs of shapes and determine if they are congruent, similar, or...
Curated OER
Making Parallel Lines
Students differentiate between parallel and perpendicular lines. For this geometry lesson, students make conjectures and apply it to solve real life situations. They collect data and make predictions based on the data.
Curated OER
Studying Special Segments in Triangles
Students investigate special segments in triangles. In this geometry lesson, students graph, compare, estimate and predict findings based on their data. They differentiate between similarity and congruence of triangles.
