Math problems of the week: 5th grade Investigations vs. Singapore Math

Polygons: recognizing terminology and properties vs. deducing area

I. A 5th grade Investigations worksheet (click to enlarge):



II. The first 5th grade Singapore Math assignment involving polygons (click to enlarge):


III. Extra Credit
One of these problems builds on a previous unit on fractions; the other one might charitably be interpreted as confusing labels with concepts. Which is which?

My wealthy suburban school district is going to start using Investigations next year. Ugh.
