Geometry Manipulative Summary Sheet

Manipulative Concept/Topic
1. Number Sense/ a. develop aptitide for problem solving
Puzzle Problems b. realize some problems have more than 1
c. illustrate alternative problem-solving
strategies
d. foster interest in mathematics
e. motivate student to persue questions, and
persist in finding solutions

2. Math Journal a. bridges to different types of learner
(multiple intelligences: interpersonal)
b. students can move from rote memorization
to algorythmic processes to generalization
of concepts, enabling transference and
extension of ideas

connections between ideas learned over
period of time

6. Tangrams a. basic geometry terms (point, line,
segment, midpoint, parallel lines,
perpendicular linesscale, proportion)

c. basic geometry shapes (triangle, iso.
triangle, square, parallalogram)
d. similarity
e. congruence
f. fractions/ratios
g. Pythagorean Formula

7. Cuisenaire Rods a. perimeter/area/volume
b. spacial relations

9. Pattern Blocks a. basic geometric shapes (square, hexagon,
parallelogram, ect.)
b. polygons
c. mosaics
d. area/perimeter/volume

11. Triangle Dominos a. triangle classification
b. a fun game

13. Paper Folding a. parallel lines

d. segment bisectors, perpendicular bisectors
e. symmetry
f. Pythagorean Formula
g. circle properties (perp. bis. of chords,
center of circle)
` h. non-formula problem-solving
g. packaging design

I am not satisfied with classifying all these items as
manipulatives. Is a math journal really a manipulative? Some
additional thought needs to be given to the classification of
types of resources. Where do graphing calculators fit into this
scheme? Geometer's Sketchpad? Various Games? Guest Experts? Internet?
Perhaps a database for resources could be developed that
we could access when we wanted to work on a particular idea or
concept.
