Written Topics for 2024-2025

  • All symbolic manipulators, including HP's and the TI-Nspire CAS, are prohibited for the frosh and sophomore levels at all meets.

Frosh

  1. Counting Basics and Simple Probability: The emphasis is on organized thinking, not using formulas. May include tree type problems, combinations, and permutations. (2023-24) (ANY CALCULATOR EVEN CAS.)
  2. NO CALCULATOR. Number Bases: May include conversion and computation in different bases (bases from 2 to 16); finding the base given some information. (2023-24)
  3. NO CALCULATOR. Basic Statistics: May include measures of central tendency (mean, median, and mode), box-and-whisker plots, two-way tables, stem and leaf, range. No variance. No standard deviation. (Resource: OpenStax: https://openstax.org/details/books/introductory-statistics). (2022-23)
  4. NO CALCULATOR. Applications of Systems of Linear Equations and Inequalities and Quadratic Equations: Limited to two variables. May include absolute value, domain, range, composition, max and min values, applications, graphs of quadratic functions, quadratic formula, and vocabulary such as consistent, inconsistent, dependent, independent. (2020-21)

Sophomores

  1. Geometric Probability: Standard treatment of probability problems with continuous variables using ratios of lengths, areas, and volumes. (2023-24) (ANY CALCULATOR EVEN CAS.)
  2. NO CALCULATOR. Logic, Sets, and Venn Diagrams: May include notation, intersection, unions, subsets, empty set, complements, universal set, cardinality of a set, solution sets, and number of subsets. Should include classic Venn diagram problems involving how many things are in various intersections. Emphasis for logic is on using logic, not formal vocabulary. No truth tables. (2021-22)
  3. NO CALCULATOR. Circles: Standard material. May include arcs, area, angles, power theorems, inscribed and circumscribed polygons, sectors and segments. Does not include trig nor equations of circles. (2022-23)
