Turtle Diary Math - Equivalent Fractions

Computational Thinker
equivalent fractions


Turtle Diary is a free online website for teachers to use. There are fun and interactive games and videos to use with the students. This program can be used with grades 1-4.

Students will:

  • Be able to find equivalent fractions by multiplying or dividing the numerator and denominator by the same number.

Vocabulary Words:

  1. Equivalent Fractions: Equivalent fractions are fractions that have different numbers but the same value. (For example, the fractions 1/2, 2/4, 3/6 and 4/8 are equivalent since each represents the same value.)
