ExplorA-Pond:1st Grade Shapes

Life Skills:

  • Thinking & Reasoning

Time Frame:
1 class period that runs 45 minutes.

Group Size:



Students will combine simple geometric shapes to represent the shape of the pond.

sample circles, squares, etc sized to match the scale of your map of the pond; Overhead projector; Overhead transparency of the map of the pond; Handout containing a map (or drawing or airplane photo) of the pond. Note: You can use a printout of the virtual pond.

Background For Teachers:
Students should have already created the following shapes in previous lessons: circles, squares, rectangles, and triangles.

Intended Learning Outcomes:
Students will investigate and predict the results of joining two geometric shapes.

Instructional Procedures:
Review the basic shapes and their associated names with the students. Display the overhead of the pond. Explain that the class goal is to represent the shape of pond using a combination of simple geometric shapes (circles, squares, rectangles, and triangles). 1. Demonstrate how to combine some of the the geometric shapes on the overhead (use at least two different combinations) and have the students describe which of the combinations best represents the pond. 2. Let the children discover what combination of shapes best represents the shape of the pond (as individuals or in pairs). Students should use their sample geometric shapes created in earlier lessons. 3. Let several individuals or pairs present their discoveries to the class. Be prepared to accept several solutions representing the overal shape of the pond.
