You're correct - patterns, parallel, symmetry, asymmetry, horizontal,
vertical, oblique, flip, rotation, reflection, geometric, organic shapes are
all words that my 3rd graders know and understand. Some of these math
concepts don't enter the math curriculum until 5th grade (check your own
local curriculum). Using rulers to measure boarders reinforces measuring
skills. If you sit down and look at a typical art lesson I'm sure you can
find at least one math concept that could be included in your teaching
without changing the lesson.
If reading is a part of your school improvement plan then teaching students
how to read a painting teaches reading skills. You can include graphic
organizers to help reinforce your lessons, as well as help with reading
