I thought I had found them all, but NO.
Subtraction. Read this

Kindergarten
Operations and Algebraic Thinking
• Understand addition as putting together and adding to, and understand subtraction as taking apart and taking from.

What has subtraction got to do with taking apart ???
(The examples are all of the form 9 = 3 + 6 and so on).
Also there is NO mention at all of subtraction as a way of finding the difference between two numbers, or of finding the larger of two numbers (anywhere).
While I am in critical mode I offer two more, less awful, horrors from Grade 1:
“To add 2 + 6 + 4,…” and “For example, subtract 10 – 8″.
The poor symbols are clearly in great pain at this point. Just read aloud exactly what is written…..
