My third grade students started a new unit on fractions this week. They’ve explored fractions before, but more along the lines of identifying different types of fractions and adding/subtracting with common denominators. This new unit involves students finding fractions of sets and a heavy dose of fraction computation. Students need to have a deep understanding of fractions to be able to add them and show a visual model. So on Friday the class practiced skills associated with finding fractions of sets. Students were given this prompt:
Draw four different ways to show 3/4 in the box below.
The student models fell into a few different categories.
- A number line
- Pie, rectangles, squares
- Dots or arrays
The class reviewed the results and we had a discussion about the different ways to represent fractions. Next week the class will be combining these models to add and subtract mixed numbers.
