NYS Mathematics Standards: Prior Knowledge: Skip count by 2’s to 12 October 21, 2009 Math 201 Objective: Students will understand unit fractions as the basis for understanding equivalent fractions. Aim: What operations can we use on the numerator and denominator of a unit fraction that will create equivalent fractions? NYS Mathematics Standards: Prior Knowledge: Skip count by 2’s to 12 Skip count by 3’s to 15 Skip count by 4’s to 20

Mini Lesson: Fractions are equivalent when they occupy the same amount of space in a whole: The area occupied by these fractions is the same! Each of these equivalent fractions names the same value and occupies the same space!

Start with the numerator of the first fraction and skip count by the same amount, then do the same for the denominator

Let’s create equivalent fractions using this method: Add 1 to the numerator to get the next numerator Add 5 to the denominator to get the next denominator

Guided Practice: Write 3 equivalent fractions for each of the following by starting with the unit fraction and skip-counting: ¼ = ____ = ____ = ____ 1/6 = ____ = ____ = ____ 1/3 = ____ = _____ = ____ Independent Practice: Open your workbook to page 32 and do problems 17 – 22 while Mr. Brooks stops by your desk to review your work.
