Find Plane Figure educational ideas and activities
In this plane figures worksheet, students color the circles blue, the triangles orange, and the rectangles red. Students then count the shapes and write how many in the blanks. Students then color the triangles purple, the circles red, and the squares green and write their number counts on the lines. Students finish by finding the plane figure for a cone.
Using an Excel spreadsheet, young mathematicians calculate the area of triangles and parallelograms. This is a creative way to have them practice this concept. Not only do they learn how to use Excel, they also practice calculating the area of plane figures. It's a win/win proposition.
Shape shifters recognize characteristics of polygons. Embracing language arts skills in addition to math, they use a thesaurus to pinpoint specific attributes of a set of polygons. They also participate in a 21-question guessing game using the attributes of polygons. This engaging lesson is helpful in addressing the Common Core initiative for geometry.
Junior geometers develop the skill of drawing various types of shapes. They are given the measurements and are expected to draw the corresponding shape. As an anticipatory activity, they spend time reviewing the vocabulary of geometry so the teacher can use the terms when describing a shape without confusion. Protractors, compasses, and rulers are used during guided practice.
Introduce learners to area and square units. They look at a bird's-eye view map of a school and answer questions about different buildings' areas. They draw squares and rectangles on a piece of graph paper and find the area of the shapes. A comprehensive lesson plan with a great, engaging opener!
Using a variety of objects, your class is introduced to polygons. In pairs they describe a piece of playground equipment using angles and lines, and then create different plane figures using plastic drinking straws and pipe cleaners. This is an engaging lesson for grasping the variety of plane shapes and comparing them based on attributes.
Plane figures have the ability to transform. They can move in three different ways. Students explore translations, rotations, and reflections as they relate to plane figures in geometry. Each student uses a digital camera to photograph 1 object, they then use their photo and PowerPoint to show how that object can be rotated and flipped. A transformation template is included.
In the "Cha Cha Slide" pupils need to slide, turn and reverse and that's exactly what this instructional activity is about. They will create a graphic organizer defining the terms: reflections, translations, and rotations then they will use Scott Foresman Investigations: Flip, Slides, and Area to show how plane figures move in space. Introduce advanced learners to the idea that Algebra is a way to mathematically describe the actions of 3-D objects.
How is a plane figure like a toy Transformer? They both have the ability to change. Students think about the ways plane shapes can transform. They practice concept vocabulary then use the computer to design their own quilt square. Their design must have at least three polygons and two transformations, when they are finished they share their quilt square with a peer.
High schoolers explore the concept of fractals. In this fractals lesson, students discuss Sierpinski's Triangle using an applet. High schoolers discuss the patterns involved with fractals. Students discuss the area of Sierpinski's triangle as the iterations go to infinity.
