A prime example is how matrices is considered a precalculus standard, even though the only math skill needed as a prerequisite is arithmetic. This is highly detrimental to students because they are systematically deprived of knowledge they could access due to false constructs. Math teachers have internalized the sequences that have been predetermined by standards and textbooks, rather than sequencing learning based on (pre)requisite knowledge. In general, teachers teach math like a ladder rather than a web."
