Curated OER
Fractions IV - Equivalent Fractions Shirley Sides
An outstanding presentation on fractions and their equivalents awaits your mathematicians. They view many excellent examples of models of fractions that look different numerically, but are actually the same in value. Terrific practice...
Curated OER
Comparing Fractions and Equivalence
There are a few ways to practice fraction skills here, and they will all appeal to visual learners. First, mathematicians fill in blanks in two fraction number sequences. Next, they analyze two fractions marked along a number line to...
