These pages begin with a very concise demonstration of fraction equality which students do with paper folding. Then we move on to using Fraction Towers to model equal fractions. The algorithm for writing equal fractions (using both multiplication and division) is derived from the examples students have created with Fraction Towers, and practice in writing pairs of equal fractions both by multiplying and dividing is included.
Fraction strips may be used if you don’t have Fraction Towers. A set of towers can be shared among two or three students.
The Smartboard 10 file has images of Fraction Towers which are cloned so you can model everything you want the students to do.
