Lesson Plan : Geometry introduction to 3D shapes

Teacher Name:
 Tricia Koning
 Grade 1

 Lesson 4: Introducing 3D shapes(cube, sphere, cone, cylinder, rectangular and triangular prisms) Classifying everyday 3D objects
 1. Students will recognize the difference between 2D and 3D shapes 2. Basic introduction to 3D shapes while modelling geometrical language 3. Students will make a connection between everyday objects and 3D shapes 4. Students will sort and classify 3D objects as a group and then independently with their worksheets
 2D cutouts 3D block shapes 5 hula hoops bag with 18 objects (1 per student) `sorting shapes`worksheets `what does it look like` worksheet pencils, scissors, glue
 -students seated at carpet, tell them that we have been learning about 2D shapes, now we are learning about 3D shapes -to make a connection, use example of 3D movie, what is the difference?
 -show students a 2D cutout of a circle and 3D block sphere what is the difference? -repeat for square/cube, rectangle/cylinder or rectangular prism, triangle/cone or triangle base prism, circle/sphere
 -tell students that we are going to play a game at the back of the room -students move slowly and quietly to form a circle at the back of the room -whoever does the best job gets to chose first -teacher hands out objects to remaining students -hoops are in the middle, place a 3D block shape in each for sorting purposes -go around the circle, each student shares what his/her object is, its shape and places it in the corresponding hoop -children return to carpet according to shape ie, spheres first
 -class-teacher discussion -student interaction and discussion -hands on activity -fun and artistic worksheets
Checking For Understanding:
 -comprehension can be observed through discussion and sorting activity -worksheets will also indicate level of comprehension
