Adding Fractions

Wednesday, April 13, 2016
We are learning all about adding fractions!

First, I gave each student 5 strips of paper - multiple colors to make it more fun, but all the same size. Then I let them work with the strips to create equal parts. We started with 1/2, 1/4/, 1/8, 1/3, 1/6 - all in that order. 

We partitioned the strips and labeled the parts. This gave students more of an understanding of taking the whole and partitioning it into parts.

Next, we started working with addition problems using the strips to help us along the way! I would give them an addition problem. (You can find the addition problem if you keep scrolling - 9/6 + 1/6 + 3/6. Before this problem, they were just 2 fraction problems, not 3.). The students knew the answer was 13/6 by adding the numerators, so we counted out 13 parts of the wholes partitioned into 6 parts. There were 5 unused, so we covered those up with red markers.

After seeing the answer represented by the strips, they were able to give their mixed number answer by seeing the 2 wholes and 1/6 left!

We currently are not simplifying (that will come later :)).
