Sample Assessment Questions
9th Grade TAKS - High School
The free response section of an Advanced Placement Exam is worth 50% of the entire score. Our
current assessment tools do not meet the challenges of this type of assessment. Preparing our future
AP students early with an AP assessment format, will promote a greater understanding of the
challenges of a rigorous Advanced Placement Math Course.
What Makes a Good Pre-AP* Mathematics
Problem?
After reading the goals of the Pre-AP* mathematics program, seeing how AP* problems can be adapted for use
at other levels. After examining exemplar problems for particular TEKS, we hope you have a better
understanding of what makes a problem or activity particularly appropriate for use in the Pre-AP mathematics
classroom. Below you will find some of the criteria that the committee used in selecting the problems and
activities for this document.

has a clear connection to the vocabulary, skills, concepts, or habits of mind necessary for success in AP
mathematics courses;
goes beyond a minimalist approach to addressing the TEKS;
can serve multiple purposes, such as addressing an Algebra I TEKS, reviewing a middle school
geometry skill, and introducing an AP Calculus concept;
should go beyond simple drill and recall (There should be a greater emphasis on analysis, application,
and synthesis of material.);
requires students to engage in an extended chain of reasoning (Problems should require more than one
step and might cover more than one topic.);
might be completely different from problems that the teacher has demonstrated in class, though based on
the same concept (Students are expected to apply their knowledge in novel situations with very little
teacher direction.);
requires students to develop their reading and interpretation skills using verbal, graphical, analytical, and
numerical prompts;
asks students to communicate their thoughts orally and/or in writing (Students must be able to justify
their work in clear, concise, and well-written sentences.);
stretches the students in ways that might make them uncomfortable (The solving of problems might take
several attempts. They might have to hear someone else's explanation (preferably one of their peers)
before they begin to develop understanding.);
should be graded based on the process and methods as well as the final answers; and
might require the thoughtful use of technology.
