(773) 534-1680Objective(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:1Emphasize 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:2First 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:3Give 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:4Give 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:5Have 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 sharesConclusions:

80% of the students received basic knowledge of fractions.References:
