CK-12 Middle School Math Concepts - Grade 6
Twelve chapters cover a multitude of math concepts found in the Common Core standards for sixth grade. Each title provides a brief explanation of what you will find inside the chapter—concepts from which you can click on and learn more...
Curated OER
Infinite Secrets
Students duplicate the method that Archimedes used to estimate the value of pi. They complete a data table and find the approximate values of pi for three sets of polygons.
Curated OER
Square Graphs
Students identify the different properties of quadrilaterals. In this geometry-lesson, students define parallel sides and diagonals of polygons as they compare to a quadrilateral. They identify the methods to find the angles in a...
Curated OER
Math: a World of Symmetry
Pupils expand their knowledge of quadrilaterals and identify basic symmetrical forms. Over three weeks, they explore the math, application, and discussion of symmetry. After conducting Internet research, students create symmetrical...
Curated OER
Geometry in Tessellations
Students examine tessellations and their geometric properties. Students explore the concept of tessellations and lines, planes, angles, and polygons. Students experiment with the area and perimeter of polygons. Students analyze...
Curated OER
Geometry Review
Seventh graders explore basic geometric definitions involving angles, area, and circumference. To reinforce basic geometric concepts, they play a "lightning Flash" card game. Students discuss chores or jobs that require the use of...
Curated OER
Circles and Pi
Students identify the relationship between the radius and Pi. In this geometry lesson plan, students calculate the circumference and area of a circle. They create visuals to help them see how the circumference relates to Pi.
Curated OER
Visual Patterns in Tessellations
Students explore tessellations as well as various types of polygon. Students examine tessellating patterns in the world around them. Students examine tessellations by creating their own tessellations and completing the included worksheet.
Curated OER
Equations Worksheet
In this math worksheet, learners create and solve equations with the help of Algebra Tiles. Then they apply formulas for geometry to find the perimeter of a polygon.
Curated OER
1st Geometry
In this geometry worksheet, students choose the multiple choice answer to 15 questions involving several different elements of geometry.
Curated OER
Cylinder: Student Worksheet
In this cylinder worksheet, students compare three different cylinders to experiment which one has the greatest volume. Students interact with rectangles as they experiment with the cylinders.
Curated OER
Geoboard Squares
Students create squares of different sizes on a geoboard. They find and describe a pattern. Students use the pattern to determine the number of squares possible on a 10-by-10 geoboard. They create squares with a horizontal base (and...
Curated OER
Penny's Box
Students need to be able to calculate the volume and surface area of a cuboid as well as present a systematic list of results in order to justify the minimum case. The use of three factors of 100 is also important.
Curated OER
Geometry
In this line and angles worksheet, students explore basic geometry vocabulary. They classify polygons. Students determine the area and perimeter of given shapes. They examine the parts of a circle, find volume and surface area of...
Curated OER
Coordinate Geometry
In this geometry worksheet, learners calculate the midpoint and distance between two points. They use the correct formula to solve the area and perimeter of polygons. There are 20 multiple choice questions with an answer key.
Curated OER
The Mysterious Hexagon on Saturn!
In this Saturn worksheet, students use a photograph of a hexagon feature on Saturn to solve three problems. These include finding the time it takes for the jet stream to complete one circuit around the hexagon, to find the size of the...
Curated OER
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
Pythagorean Theorem by Graphic Manipulation
There are many different ways to show a proof of the Pythagorean Theorem. Here is a nice hands-on paper cutting activity that shows a graphic representation. You can even challenge your young Pythagoreans to come up with their own...
Curated OER
You Can Count on Squares!
Fourth graders engage in and explore to develop mathematical, specifically algebraic, ideas. Although the tasks are built around measurement, they are algebraic to the extent that they require 'formulae' to be derived form the geometric...
Curated OER
Making Rectangles
Students study rectangles. In this math lesson, students use numbers, measurements and geometry to draw rectangles of varying sizes.
