The teacher plans to teach kindergarten students about 2D and 3D shapes through hands-on activities including videos created by the teacher, webquests, and identifying shapes on a poster. Students will watch videos on 2D and 3D shapes, complete individual webquests on each type of shape, and then identify shapes on a poster as 2D or 3D. The teacher will evaluate students' understanding through the interactive poster activity and by reviewing their individual webquests.
