ACTIVITY
Create an Equivalent Fraction Counting Books. Using the Fractions;
• ½• 1/3• ¼• 1/5• 1/6 create a page for each. Each page can be
divided into two sections one with the original fraction and the other side containing the equivalent fraction. Each page should include pictures, words and numbers.
