Try the latest teaching guide for Fractions Intro. Just like the three-day lab for Circuit Construction Kit (DC Only) featured in our blog last week, this three-day activity was also developed between Meaghan Hixson and our PhET Team.
- Day 1: What is a Fraction?: students explore what makes a fraction by manipulating numerators and denominators. Through discussion and various fraction representations, students learn that numerators are the number of pieces being considered and the denominators are the number of equal pieces in a whole.
- Day 2: Comparing and Ordering Fractions: students use their knowledge of numerators/denominators from Day 1 to compare and order fractions and come up with rules for discussing the size of fractions.
- Day 3: Equivalent Fractions: students explore fraction equivalence using the Build a Fraction sim. By using the sim to create various representations of the same amount, students explore and discuss rules for finding equivalent fractions.
