Topic: Introduction of Fractions
Time Duration:45 minutes of lesson and 15 minutes of class work,
Grades: K-7th
The instructor began class by explaining how to understand the numerator and denominator of
a fraction. The numerator was expressed as the portion of a certain group. The denominator
was explained to be the number of proportions a item has. For example, if there was one
rectangle cut into four equal parts, the denominator would be 4 because it is cut into four
proportions. The students participated in constructing fractions. They were given pieces of
paper and asked to put them together. The pieces of paper were cut into fractions like 1/2
and 1/3. The instructor explained how to make a whole fraction. The students were given a
challenge, after they understood how to construct a fraction and how to distinguish a
fraction. The challenge was to identify how many different pieces of candy can be divided
into fractions. For example a Kit Kat bar can be divided into 4 pieces, so a whole candy bar
could be represented as 4/4. The instructor would then ask, "how many portions does a Kit
Kat bar have, if it is divided in half?" The students would reply 2/4. When a student
answered the question correctly, they were able to keep that candy to eat.
