Today in class, we learned about adding fractions. Mr. Harbeck gave us an example which was, 1/2 + 1/3. He said it equaled 2/5, and asked if it was correct.

This picture says, 1/2 + 1/3 is bigger than

2/5 when you compare it. So it makes it wrong.

What you need to add fractions is common denominators (you get it by multiplying the 2 denominators) and the same size pieces. So for 1/2 + 1/3, the denominator is going to be 6.

Joysie 817said...Great Job, Erika.

I loved your pictures. It helped me learn how to make fractions in rectangles instead of circles. :P And i love your pictures! They were so colorful. I especially like the last one. Purple!!

I think you make some Spelling/Grammar mistakes, but that can easily be fixed.

Other than that, You did an awesome job!!! ☺
