Polygon Capture: A Geometry Game
Students classify polygons according to more than one property at a time. Students must move from a simple description of shapes to an analysis of how properties are related, all in the context of an enjoyable game.
3-D Visualization Activity
Students use 3-D visualization and reasoning when beginning this lesson. Using new vocabulary, they identify the different types of polygons. They complete journal entries on a weekly basis on problems solved. They draw their own 3-D object to complete the lesson.
Sort It Out and Match It Up
Students identify objects that are the same shape and size. They compare and contrast attributes of two-and three-dimensional objects using appropriate vocabulary. Pupils justify an extension of a geometric pattern to explain what was done and why it was done.
Students work together to make figures out of tangram squares. In groups, they calculate the measurements they need and apply the Pythagorean Theorem. They complete a worksheet solving equations using the theorem and review their answers.
Here is a fabulous activity on shapes for young elementary learners. They view a presentation on shapes that is led by the teacher, then construct shapes on their own using paper, straws, tape, and other supplies. Fantastic worksheets are embedded in the plan, as is the weblink that the teacher accesses to show the presentation. A terrific math lesson plan!
A Cone and Its Net
Create and investigate nets for solid shapes with your class. They identify the different parts and faces of each polygon and solid then calculate the surface area and volume of cones. They use circle sectors of varying sizes to build cones. Resource contains zero procedural details.
First graders make a picture using a triangle, rectangle or circle and share with a neighbor the shape they used to make their object. They then sort their objects by shape. Students are then sent on a scavenger hunt to take pictures of objects around the school that are cones, rectangular prisms or cylinders with a digital camera.
Identify Solid Shapes
In this solid shapes worksheet, students name and describe the solid shapes on the left. Students color the objects that are like the solid shape.
In this solid shapes worksheet, students learn to identify and solve word problems that use solid shapes. Students solve six word problems about solid shapes.
In this solid shapes worksheet, students learn to identify solid shape faces. Students identify the solid shapes and the faces in the six word problems.
Classify and Compare Solid Shapes Practice 8.4
In this solid shapes worksheet, students analyze pairs of solid shapes and write how the pair is alike and different. There is an example on the page.
New! Using Linear Equations to Define Geometric Solids
Making the transition from two-dimensional shapes to three-dimensional solids can be difficult for many geometry students. This comprehensive lesson starts with writing and graphing linear equations to define a bounded region and calculating the areas and perimeters of the space. Using this as a base, the lesson then has learners revolve these regions to create solid figures and calculate the resulting volume. A real-world example using a bowling ball and visualization software caps off this in-depth instruction.
New! Exploring at the Nanoscale
Nano-nano! Nanotechnology can seem like it's from another planet! After learning about this tiny technology, collaborative groups experiment with how smaller particles affect chemical reactions. They do this by immersing a whole and a crushed antacid tablet into equal amounts of water. Nanotechnology is a fascinating topic for your STEM curriculum.
Shapes are Everywhere
Multiple strategies in this lesson plan will enhance learners' knowledge of shapes. First, they will work in pairs to guess and explain a solid shape using math terms. Then, the class will observe a photograph of a large city and identify different shapes throughout the scene. Finally, they will use digital cameras to take pictures of different shapes they can spot around the school. Tip: If you do not have access to digital cameras, make drawings!
2: Isle of Shapes - Based on the Puerto Rico Quarter Reverse
Students identify both two and three-dimensional shapes. In this geometric shapes instructional activity, students listen to a teacher led instructional activity about the island of Puerto Rico. They look at the symbols and shapes on "Puerto Rico Quarter Reverse" on a transparency. They complete associated worksheets by drawing items in the classroom that match the given shapes and coloring the coin.
Attitude Determines Altitude
A fabulous lesson which combines mathematics with space science. Middle schoolers work in cooperative groups in order to research early astronauts and their accomplishments. They look at a variety of rocket and space shuttle designs, and use Newton's laws to plan, design, and build a paper rocket. There is an abundance of worksheets, websites, and other support materials to help learners successfully complete their tasks. A terrific cross-curricular lesson!
Fish Tank Problem
Thomas needs help with his fish tank! He wants to add a large decoration that will serve as a home for the fish in the tank. The decoration is a right solid cylinder with a hole through the middle in the shape of a right square prism. Thomas wants to make sure that the water in the tank won't overflow when he adds the decoration. Geometers use volume formulas for cylinders and prisms in this real-world problem that requires them to consider different interpretations of how the information is presented.
Here is a cute problem that requires visualizing two-dimensional shapes within a three-dimensional object, and using properties of triangles and the Pythagorean theorem to solve a real-world problem. There is a small mistake in this problem, that your charges are sure to let you know about. Clown fish are not goldfish, and two couldn't live together in the same fish tank. If this fac becomes an obstacle, then challenge them to rewrite this problem in a totally different way.
Middle schoolers construct a three-dimensional model of a city using both similar and congruent figures and geometric transformations. City must have at least ten buildings with each building labeled and may be constructed out of paper or modeling clay. A two-dimensional representation, drawn to scale, must be included as well.
Identifying Lines of Symmetry and Creating Reflections over a Line
Fifth graders review the concept of a line of symmetry by using pieces of paper that have pictures such as, letters of the alphabet, polygons, and designs made from polygons in order to determine if they have symmetry. The fine, two-hour session should lead to a much greater understanding of symmetry. Terrific worksheets are embedded in the plan which support your teaching, and some innovative extension activities are described as well. A very impressive instructional activity!
