```Introduction to Fractions Using Cuisenaire RodsGwendolyn M. Manson            Benjamin Banneker                               6656 S. Normal                               Chicago IL 60621                               (312) 535-3020Objective(s): Grade 5

(1) Students will visually "see" and manipulate fractions with Cuisenaire
Rods staircase to develop concept and fractional relationships.
(2) Students will learn numerical values of rods and relate them to color
and length.
(3) Students will use varied approaches to discovering new fractional
relationships that answer the "why" in fractions and lessen "the only
one way" hazard.
(4) Students will write a problem-solving story that is interest-based but
also demonstrates basic understanding of fractions and vocabulary
usage.
(5) Students will relate fractions in a relevant way to their culture.

Materials Needed:

(1)  Cuisenaire Rods - One set per student
(3)  Overhead Cuisenaire Rods - 1 set per class
(4)  Acetate Sheets - 6 per class
(5)  Grease Pens - Two per class
(6)  Poster Boards - One per five groups
(7)  Magic Markers - One per five groups
(8)  Worksheets (2) - Two per student

Strategy:

(1)  Display objects and discuss why fractions are important and
needed in real-life situations, i.e. sewing, fabric measurement,
money, recipes, telling time, body measurements, etc.
(2)  Students will work in cooperative groups (A-E) and build a rod
staircase.
(3)  Students will explore, examine and learn the colors, lengths and
numerical value of each rod.
(4)  Students and teacher work together using the Overhead Projector
with Cuisenaire Rods to develop and write fractional equivalents
and relationships.
(5)  Learners will make values of ten using each of the colored rods.
(6)  Students will do multiples of the white, red and light green rods.
(7)  Display an orange rod and show that it takes two yellow rods to
make an orange rod.  Write in the following manner:
O     = 2 Yellow
1/2 O = Y
(8)  Do the same with the Red (R), Dark Green (D), and Brown (N) which
are multiples of two.
(9)  Students discover the multiples of three, i.e. E=3G read as Blue
equals three Green, 1/3 E=G.
(10) Students will do a self checking worksheet to answer a Cuisenaire
Rod riddle.
(11) Students will form cooperative groups (A-E) to write a mathematical
story for a specific combination of Cuisenaire Rods displayed on the
