Three Dimensional GeometryBritney Jenkin

IntroductionIn this unit, the students will begin to focus on defining attributes of three-dimensional shapes. They describe and sort shapes according to their attributes. This provides a foundation for classifying shapes in later grades, These experiences will help the students to look for and make use of structure in geometry as well as in the physical world.

Objective

The objective of thisunit is to teach students how to identify, sort, and compare three-dimensional shapes.

Assessment

Instructional PlansThis Unit will be taught over a one week period with one lesson a day. Each lesson will have an activity, a worksheet, and homework to reinforce the lesson.Three different types of instruction will be used to teach the lessons: Concept Formation, Learning Cycles, and Direction Instruction.Concept Formation introduces the lesson and then guides students to list, group, label, and regroup objects or concepts. The students are then asked to generalize what they have learned and then participate in a closing activity.Learning Cycles engages the students through questions and activities and then guides them to explore and explain new concepts. Those concepts can then be expanded before closing the lesson.Direct instruction introduces and presents new concepts while checking for understanding and guiding the students through practice.

Teaching ReflectionsVerbal and NonVerbal Strategies• "Give me Five"• Hold up hand• Complementing well behaved students• Reminding students of the rules• “One of Three Ways”

Activity #1Activity #2Scavenger HuntEach student is assigned a shape and asked to find something of the same shape in the classroom.Activity #3Building 3D ShapesGive each table group six 3-D shapes and have them build a larger shape. Have them describe the shapes they used.

Conclusion

At the end of the unit, the students were able toname three-dimensional shapes, locate them around the classroom, and label the two- dimensional shapes on the faces of the three-dimensional shapes. They were also able to count the number of faces and vertices oneach of the three-dimensional shapes.

Introduction

It is important for students to learn about three-dimensional shapes because shapes are all around us and are used to make up the objects around us. The students will need to understand these shapes in order to understandthe world around them.
