Explore different representations for fractions including improper fractions, mixed numbers, decimals, and percentages. Additionally, there are length, area, region, and set models. Adjust numerators and denominators to see how they alter the representations and models.
“This time, divide 3/4 by 1/8. Let’s place as many 1/8 strips as we can to match the 3/4 strip.” Model it and then walk around to help students who may need support.
