Round to the Nearest Whole $
In this rounding money activity, students identify the money amounts in each examples and round to the nearest dollar for the 10 examples.
Curated OER
Transformations
Tenth graders recognize, perform and derive rules for basic transformations including translation, reflection and rotation. They also consider compositions, a combination of two or more basic transformations. Students explore both...
Curated OER
Shape Makes a Difference!
Students learn the difference between perimeter and area by watching a video and a hands on activity.
Curated OER
Cracks on the Walls
Learners observe the cracks in school walls and pavements. In this geometry lesson, students explore the factors to be considered before building a structure. They complete a graphing and calculation worksheet after the lesson.
Curated OER
Deer Tracks
Students use satellite images to track to movement patterns of deer and examine deer behavior. They write stories about a day in the life of a field scientist.
Curated OER
Grasping Geometry
Students investigate geometric shapes in their environment, make a geometric design, and write paragraphs describing the design.
Curated OER
Geometric Glossary
Fourth graders use drawing and paint tools to identify, draw and state several geometric terms.
Curated OER
A Real Difference
Fifth graders use the Celsius and Fahrenheit thermometers to compare temperature readings. They use the Internet to find the temperatures of selected cities. After data is collected for five days, 5th graders graph the temperatures.
Curated OER
Pythagorean Theorem Investigation
Eighth graders investigate the Pythagorean Theorem and practice applying the theorem to various triangles. Finally, in the next lesson in the sequence, 8th graders create a song or a story to help them remember the Pythagorean Theorem.
Curated OER
Mathematics: The Star of David
Sixth graders determine the number of triangles in the Star of David.
Curated OER
Exploring Arrangements of 2, 3, 4, and 5 Cubes
Pupils construct models of various tricubes, tetracubes, and pentacubes that are possible, classify n-cubes into different groupings, and draw these figures on isometric dot paper giving true perspective to what they visualize.
Curated OER
Two-Dimensional Drawings from Three-Dimensional Objects
Sixth graders identify and draw two-dimensional representations of a three-dimensional object. Students investigate the views of an object and determine that three views are required (front, one side and the top). Students use these...
Curated OER
Slides, Flips and Turns
Third graders are introduced to different types of transformations. As a class, they describe how a stuffed animal slides across the floor and use themselves to demonstrate as well. Individually, they flip and turn in different...
Curated OER
Symmetry
Sixth graders explore symmetry and discuss the difference between a rotation and reflection. Using hands-on activities, such as folding paper shapes, they discover how to find the lines of symmetry and symmetrical characteristics. As a...
Curated OER
Back to the Bees (Tesselations)
Sixth graders observe the creation of a tessellation with hexagons. In groups, they work with polygons to discover what shapes can be used to create tessellations and explore the angle measurements of each shape. Using internet websites,...
Curated OER
Angle Benchmarks
Sixth graders discuss the characteristics of specific angles and then use the information to to identify and estimate given angles. The class goes outside, identifies north, and turns a specified amount of degrees. Using a given compass,...
Curated OER
Calendar -- Months of the Year
First graders study the months of the year. They enjoy making a class book using their birthdays and the types of weather in that month. After a lecture/demo, 1st graders utilize a worksheet imbedded in this plan to design their book.
Curated OER
Congruent Triangles - Is This Enough Information?
Seventh graders examine congruence postulates and apply knowledge to triangles in the world around them.
Curated OER
How Does Kansas Measure Up?
Students identify the five main crops of Kansas and crops that are produced in other states. The categorize the types of fruits and seeds of each plant and measure each to compare the length of each.
Curated OER
Modular Houses
Students, working in pairs, are presented with the problem. They are asked to design modular houses using four cubic modules, all the same size, which touch each other on complete faces. They must draw each of their houses on isometric...
Curated OER
Justifying Mathematical Conjectures
Sixth graders, in groups, explain why they think something. This requires students to listen to and respond to each other. In this particular lesson, 6th graders explain to their classmates when one can or cannot construct a specific...
Curated OER
Model Sails: Investigating Sails of Tall Ships
Students investigate the dimensions of a full-rigged ship and a schooner. Using the dimesions, they calculate and compare the area of the sails. In groups, they create model sails that require modeling and estiminating using the...
Curated OER
Volume Of Tetrahedron With Congruent Faces
Ninth graders investigate the concept of a tetrahedron and how it is formed with its congruent faces. They practice making the shape by practicing the folding paper to create the shape. Students continue the lesson with the estimation...
