This document discusses different types of graphics that can be used for learning geometry:
- A mnemonic graphic uses two syllables ("pem" and "das") to help students remember the order of operations (parentheses, exponents, multiplication, division, addition, subtraction).
- Decorative graphics can be distracting if they include concepts not relevant to the course, like including i in a high school geometry class.
- An interpretive graphic would show the parts of a perpendicular line constructed with only a compass and straightedge to help with constructions.
- A relational graphic could review algebraic properties like the commutative and substitution properties of addition that are important for proofs.
- A transformational graphic animating
