Working With Functions, Statistics, and Trigonometry From the UChicago SMP Curriculum
The University of Chicago School Mathematics Project materials on functions, statistics, and trigonometry take a fairly rigorous approach compared to many standard high school texts. If you are trying to use these resources or understand how they operate, there are some practical things you need to know before diving in. This curriculum was developed as part of the broader SMP initiative that attempted to modernize secondary mathematics instruction. The treatment of functions comes early and with more abstraction than most state standards require. Statistics and probability receive substantial attention, often earlier than traditional curricula place them. Trigonometry is introduced through a unit-circle foundation rather than the right-triangle-first approach common elsewhere. The book organizes content around conceptual coherence rather than topic isolation. Functions appear repeatedly across different contexts. You will see linear relationships, exponential growth, and periodic behavior treated as variations on a single underlying idea. This means earlier chapters on notation and mapping matter. If you skip the preliminary material on function notation and domain restrictions, the later trigonometry sections become confusing quickly.
The statistics portions emphasize data distributions, sampling variability, and basic inference. The trigonometry sections build from the unit circle through graphs of sine and cosine, then into solving triangles and applied problems. The exercise sets tend toward longer, multi-step problems rather than repetitive drill.
Practical Issues You Will Encounter
I ran into a specific problem when working through the trigonometry proofs section. The text assumes familiarity with radian measure and the geometric definition of sine and cosine before introducing exact value tables. Students who come from programs using degree-only approaches often stall around Chapter 8 or 9. The workaround I found was to pause and review the unit circle constructions separately. Working through the coordinate definitions of trigonometric functions on graph paper for a full week cleared up most of the confusion. It added time upfront but prevented repeated backtracking later. Another issue involves the statistics problems. They sometimes present real data sets with incomplete information, asking students to make reasonable estimates. This is pedagogically sound but frustrating if you expect a single correct numerical answer. The text does not always signal whether rounding conventions apply. I learned to check the preceding examples for rounding patterns before submitting work, since the expected answers depend on those implicit conventions.

Common Pitfalls and Counter-Intuitive Points
One thing beginners miss is that this curriculum treats inverse trigonometric functions as restricted-range mappings from the start. Many students expect arcsin to return multiple angles. The text does not accommodate that interpretation at any point. Attempting to use general solution forms in the early chapters will conflict with the stated domain and range definitions. A second nuance involves the probability sections. The authors often use simulation-style reasoning before formal counting rules. If you jump straight to permutation formulas without understanding the underlying sample-space construction, you will make errors on compound event problems. The curriculum deliberately delays formula application until conceptual grounding exists. Rushing ahead usually produces careless mistakes on test problems involving dependent events or conditional probability.
What This Curriculum Does Not Handle Well
The treatment of statistics leans heavily toward conceptual understanding and data analysis. If you need rigorous computational practice with statistical software or advanced hypothesis testing procedures, this text will not provide it. The trigonometry sections also move quickly past identities into applications. Students preparing for competitive math contexts may find the identity work insufficient and will need supplementary problem sets. For learners who need more procedural drill or step-by-step worked examples, pairing this curriculum with a traditional problem set book helps. The UChicago SMP approach prioritizes depth over breadth, which works well in a classroom setting with teacher guidance but can leave self-learners without enough scaffolding.
Using the Materials Effectively
Read the introductory sections carefully. The function notation and mapping language used in the first three chapters recurs throughout. Skipping them creates gaps. Do the exercises in order rather than picking problems by topic. The sequence builds dependencies that jump-around practice disrupts. For trigonometry, spend extra time on the unit circle derivations. The exact values and sign rules established early save considerable time later. When working statistics problems, write out the sample space explicitly before applying formulas. This habit reduces errors on conditional probability questions significantly. If you are teaching from this curriculum, plan for longer class periods or additional supplemental exercises. The problems are dense, and students benefit from guided discussion before independent practice. The material assumes sustained engagement rather than quick coverage.

Availability Considerations
These texts are older publications. Current editions may be available through educational publishers or secondhand markets. Digital copies sometimes appear through academic repositories, but legality and completeness vary. Verify that any version you obtain includes all problem sets and answer keys if you are studying independently. Incomplete editions cause unnecessary frustration. The curriculum remains useful for educators seeking a more conceptual treatment of functions and trigonometry. It also suits students who want earlier exposure to statistical reasoning. The main trade-off is less procedural repetition and a faster pace through standard topics. Plan accordingly based on your goals and background.
