Strategy
Strategy: Finger Math in Geometry
Appropriate Grade Level: Any grade that covers geometry
Procedures/Steps:
-Originally used for English language learners, but is effective for all
students
-Acknowledges non-verbal communication, and uses it to enhance learning
of geometry concepts
-Develop a series of hand signals for geometrical terms
(ray, parallel lines, parallel planes, rectangle, right angle)
-Teacher demonstrates hand signal that will reinforce meaning when
introducing a concept
-Help trigger memory when reviewing for exams by having student explain
a particular geometrical term through both spoken words and hand signal
-Very effective for visual learners
-Allow students to have fun and be creative
-Be sensitive of using signals in certain areas (high gang activity areas) to
avoid confusion or miscommunication
Comments and/or tips:
Hand signals are meant as a means to reinforce learned geometrical
concepts. The teacher may demonstrate some signals, but allowing students
to create their own will create opportunity for a better connection. Digital
cameras can be used to photograph hand signals and make flashcards to help
students memorize signals.
