Teacher Name:

Grade:
 Grade 1
Subject:
 Math

Topic:
 Lesson 4: Introducing 3D shapes(cube, sphere, cone, cylinder, rectangular and triangular prisms) Classifying everyday 3D objects
Goals:
 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
Materials:
 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
Introduction:
 -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?
Development:
 -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
Practice:
 -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
Accommodations:
 -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
