Fractions

Mattie Drane Crown Academy School

Objective(s):

Identify the numerator and denominator of a fraction. (Grade 1-4)

Materials Needed:

Crayons or markers, construction paper, Dominoes, M&M Candy, fruits, toothpicks,
large bowl, paper cups, papers, pencils, paper towels, plastic knife

Strategy:1 Emphasize that the down number, (denominator) tells how many fair
shares are in the whole object and that the top number, (numerator) tells how
many of the shares are being talked about.

Strategy:2 First have each student study a blank sheet of paper. Ask, "How
many folds have you made?" Next have each student fold his/her paper in half,
then unfold it. Ask students how many folds they made, how many fair shares
they have and what each fair share is called. Have students write 1/2 on each
fair share. Then have each student fold a second sheet of paper twice to
create four equal shares. Prompt students to tell that they made two folds and
have four fair shares that are each called one-fourth. Then give students
oral directions for coloring their papers such as "Color one-fourth red, two-
fourths blue, and one-fourth yellow." If desired, have students turn these
papers over and repeat the sequence, this time create your own fair shares.

Strategy:3 Give each of several small student groups a handful of dominoes.
Explain that each domino features a set of dots that has been divided into two
parts. Instruct each student to draw each of his/her group's dominoes on a
sheet of drawing paper. (Students can trace the domino shapes, then draw the
dots.) Below each domino, have each student write the two fractions that
describe the domino's dot arrangements. If desired, challenge students to add
each pair of fractions-to make a whole!

Strategy:4 Give each student 12 M&M candies. Have each student identify the
fractional part of his/her set represented by each color of candy. To extend
the lesson, have students eat a portion of their candies, then repeat the
activity using their net sets.

Strategy:5 Have each student bring one fruit item to school. While students
observe, cut each piece of fruit into fractional parts. For example, an apple
could be cut into halves, quarters, and eighths. Or a banana could be cut into
thirds, sixths, and twelfths. Have students identify the fractional parts as
they are formed. Mix the fruit pieces together in a large bowl; then serve
the fruit salad in paper cups. Have students use toothpicks as their eating
utensils.


Performance Assessment:

1. Questions & answers
2. Teacher observation
3. Students will create their fair shares

Conclusions:

80% of the students received basic knowledge of fractions.
