Product Description
Did I ever tell you that I design amazing assessments? Everybody says so: they are the best assessments you've ever seen. The other assessments you've seen? They're a disaster.

Sad.

This is a percent assessment that is unlike any that you have ever done. First, it requires your students to use scissors! Second, there are very few "clean" numbers (that is, exact numbers) because, well, life is NEVER exact! Third, it assesses on concepts and skill AND problem solving, so your students have to interpret remainders. Oh, and while there are problems that can be solved by "inspection" (that is, looking for efficient solutions), many of the problems also require using a calculator, although they will still have to set up the equations to solve them....

Oh, and it's kind of fun.

Here's how it works; there are 12 different problems of three different types: those where you have to calculate a percent, those that require finding percent of a number and those where you know the percent and the percent amount, and you have to find the original amount. There are 4 groups of problems, with three problems (one of each type) in each group.

Task #1: Students cut out the twelve problems and then sort them into three groups. They paste the problems onto the solution sheet based on what proportion they would use to solve the problem

Task #2: Students set up the problem as a proportion.

Task #3: Students shows the steps needed to find the solution. However, there are 3 problems (one in each group) where the students can use more efficient methods than cross products to solve the problem: in fact, they use a common factor which saves some work. But if your students are just blindly following an algorithm instead of actually "looking" at the problems, they won't see it, will they?

Task #4: Students have to interpret the answer, because the 9 problems that require a calculator do not come out evenly, at all. Which means your students are going to have to round up, round down, or even discard the remainder altogether.

There are two sets of detailed rubrics which explain how to assess the student's work: one is a "wholistic" approach, while the second set of rubrics use a numerical assessment. Assessment rubrics include using alternative methods for finding the solution and interpreting remainders and stating the solution so that it makes sense (as in: there's no such thing as shooting a basketball 32.1 times.)
