Measuring Body Angles
Students use technology to graph and compare angles. In this geometry lesson, students range of motion in the environment. They identify the missing parts of polygons using similarity and congruence.
Curated OER
Geometry Jeopardy
Students identify the pattern in a problem. In this geometry lesson, students make predictions, collect and analyze data. They apply the idea of scales and measurements to the real world.
Curated OER
Analyzing Body Angles
Students investigate angles of polygons. In this geometry instructional activity, students identify the relationship between angles and the number of sides in a polygon. They differentiate between sumilarity anf congruence in angles and...
Curated OER
Identifying Lines of Symmetry
Students calculate the lines of symmetry using polygons. In this geometry lesson, students graph, compare and estimate using collected data. They identify different attributes to the polygons based on their sides.
Curated OER
Studying Special Segments in Triangles
Students investigate special segments in triangles. For this geometry lesson, students graph, compare, estimate and predict findings based on their data. They differentiate between similarity and congruence of triangles.
Curated OER
Sum of the Parts
Fifth graders build objects using various materials. They estimate the weight of the object using individual building pieces. Then they weigh the actual object and then tear it apart and weigh the pieces. They compare the two weights.
Curated OER
Separating Soup Mix
Students use screens of three sizes to separate a mixture of five solid materials. They plan and conduct simple investigations using appropriate tools, measures, and safety rules and record and report observations, explanations, and...
Curated OER
Adding and subtracting fractions: the same sized slice
Students establish a strategy for adding simple fractions. They convert improper fractions to mixed numbers and interpret drawings and storyboards.
Curated OER
Classifying Transformations
Students analyze different polygons by shapes and sides. In this geometry lesson, students differentiate between similar and congruent polygons. They name the different polygons based on the number of sides.
Curated OER
Hexagon Island
Students identify different polygons. In this geometry lesson, students name polygons using the number of sides. They calculate distance and slopes using the correct formula.
Curated OER
Real Life Application of Area and Perimeter
Fifth graders explore real-life situations of area and perimeter. They develop a list of real-life applications of area and perimeter, select a situation, and write a step-by-step procedure and diagram on graph paper for solving the...
Curated OER
More on Least Squares
For this least squares worksheet, students solve 3 different problems that include determining the least squares of equations. First, they use the data given in the table to write out the normal equations a system of 2 equations in 2...
Curated OER
Using Concept Maps to Design 3D Spheres
Pupils create three dimensional shapes using concept maps. In this geometry instructional activity, students investigate the impact of mental schemas on humans. They collect data on this topic and plot their data on a coordinate plane.
Curated OER
Circle Art
Students investigate two and three dimensional shapes. In this geometry lesson, students write equations of circles and graph them correctly. They create pictures using circles.
Curated OER
Making Parallel Lines
Young scholars differentiate between parallel and perpendicular lines. In 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
Similar Triangles - Applied Problems
Students differentiate between similar and congruent triangles. In this geometry lesson, students identify the angles of triangles using the similarity theorem. They apply concepts of triangles to the real world.
Curated OER
Tallies Tell It All
Students explore data collection through the use of tally marks. After a demonstration of the use of tally marks students complete various inquires where they create a chart documenting the number of times a desired result happens. They...
Alabama Learning Exchange
Partying with Two/Three Digit Whole Numbers
Learners practice problem-solving with this addition activity. They plan a party for their class and another class by determining how many cupcakes are needed. Students draw a picture of how they determined the number of cupcakes.
Curated OER
Scalene Triangles
Fifth graders identify and classify scalene, equilateral, and isosceles triangles. In this triangle lesson, 5th graders define the different attributes of 3 types of triangles and sort them by descriptions and...
Curated OER
Sketching Spheres
Students investigate spheres through sketches. For this geometry lesson, students sketch two and three dimensional shapes creating nets. They find and differentiate between the nets for prisms, pyramids, cones, cylinders and spheres.
Curated OER
Geometry Slideshow
Sixth graders create slideshows of geometric terms. They use images taken with digital cameras or scanned from magazines.
Curated OER
Traveling Sound
Students explore how sound waves move through liquids, solids and gases in a series of simple sound energy experiments. They describe how sound needs molecules to move and that changing the medium that it travels through changes the...
