This PowerPoint contains two lessons. It aims at teaching the standard NF 4a: Decompose a fraction into a sum of unit fractions. This standards actually breaks out into 3 separate lessons.
I first teach my students to decompose a fraction by adding. For example, 3/4 = 1/4 + 1/4 + 1/4.
Then I teach the two lessons attached next. The first lesson: 3/4 = 3 x 1/4.
The 2nd lesson decomposes a fraction multiplied by a whole number. For example, 2 x 3/4 = 2 x (3 x 1/4) =
6 x 1/4.
