Integrating internet resoucres into lessons

An Introduction to 3-D Shapes (Grade 2)

GLO:
Name, describe and construct a variety of 3-D objects and 2-D shapes.
SLOs:
18. Explore faces, vertices and edges of 3-D objects.
19. Identify, name and describe specific 3-D objects as:cubes, spheres,cones, cylinders, pyramids.

Activity:
Utilizing an interactive geometric solids utility(National Council of Teachers of Mathematics), the teacher can accurately articulate and display to the students the definition of a face, a vertex, and an edge. With the utility, students can count faces, vertices and edges on a number of different 3-D shapes.
With the aid of another online resource (Primary Resources), a simple slide show, the basic 3-D shapes can be viewed and named. While each new shape is viewed, students can mark on the smartboard each shape's faces, vertices and edges.

Relevant ICT Outcomes:
C6 Students will use technology to investigate and/or solve problems.

Rationale for integrating technology into this lesson:
Two different resources were used as visual aids in the lesson. The first made use of the technology to visually express a concept which can be difficult to get across to students when limited to 3-D models or drawings on a whiteboard. The second resource was a simple pictorial presentation of shapes which may have taken the place of flash cards or a teacher drawing on a whiteboard. The benefit of the slide show is it's speed and simplicity in presenting a straight-forward introduction of the lesson. An added benefit is the possibility of having students approach the smartboard and draw on the shapes to assess their understanding of the concepts of faces, vertices, and edges.
