Fraction Ordering with Lowest Common Denominators: Test Your Strength
Young mathematicians use a bell and hammer to see how high or low the puck goes. Then, they order the fractional values to demonstrate the greatest to lowest hit. Students then respond to several questions that require them to use...
Curated OER
Comparing Fractions
Young mathematicians compare two fractions with like denominators and then move to the next level to compare fractions with unlike denominators. They will first try to use mental math to make educated guesses. There are a few guidelines...
