This is a 4 page assessment for fifth graders, although sixth and seventh graders will find it challenging, as will advanced 4th graders. As stated, it is balanced between concepts, skills and problem solving (as opposed to "regular" tests which focus on skills like creating equivalent fractions, "reducing" fractions and adding/subtracting fractions.)
Here are the features of this exam:
1) It uses a variety of models, including an area model using pattern blocks, and the linear model on a number line.
2) It uses the correct language: you don't "reduce" fractions, you "simplify" them. There is no such thing as "mixed fractions" - they are "mixed numbers."
3) It tests students on estimation: there is a question where students have to name three fractions and place them on a number line between 1/4 and 1/5.
4) It is not an endurance test: with 4 pages of questions, and only 6 of them involving computation, your students should be able to finish it within a 45 minute time limit. Not sure if they'll be able to do it? Then give the first 2 pages on one day for 30 minutes and pages 3 and 4 on the second day for 30 minutes.
5) Students are required to justify their answers: there is ample space for students to show their work, and in many cases, students have to write in full sentences (as in a section where they have to define the following and give 3 examples: unit fractions, complex fractions, improper fractions and mixed number.
This is an excellent assessment that you can use to decide what it is your students should know about fractions at the fifth grade level. I can also customize it for you if you have a special need for a certain type of question.
