Geometry: Shapes, Partial/Whole

A large group game with an air of mystery for expanding perspective in shapes and a table project that stands up under repetition.

Objectives

Children ages 4-5 years can recognize a partially shown object when only smaller segment is visible Lang. IIC
and they can use paste to join paper FM II
Ages 4 can recognize a part shown when only the largest segment is visible Lang. IIC
Ages 2-21/2 years can match shape to complete outline of that shape Lang. IIIA

 

Materials

Mr. Math puppet; screen or box; different sizes of cardboard or flannel shapes; envelopes each containing a shape cut into 2-6 pieces; worksheets with pre-drawn outlines of whole shapes to use as "frames" for puzzle assembly; glue.

Procedures

1. Large group: Mr. Math reaches behind screen or into box and shows larger segment of shape. "What shape is this?" Continue game, diminishing the size of the shape segment shown. Children can take turns bring the teacher and show each other parts of shapes to identify.

2. Small group: Seated around table, each child gets an envelope with cut-up shape inside, and, on the outside, the shape which the pieces will make when assembled; and a worksheet with outline(s) of same kind of shape as on envelope. Younger children should get shapes cut into fewer pieces and perhaps worksheets with only one outline apiece. Each child sets about assembling own puzzle within outline on worksheets. If a child has difficulty, teacher might place one piece or try giving some verbal help, but try to let child work independently. (Better to give child a shape in fewer pieces that interfere too much or let him/her feel incompetent.)
