One-question survey:
Are these read-throughs useful to you?
Expressions versus Sentences April 15, 2020 My first read-through!
Simplifying $\,(a+b)^2\,$ and $\,(a-b)^2\,$ April 16, 2020 I made the decision to read the mathematics aloud as simply as possible, assuming someone is looking at the mathematics. Thus (for example) for $\,(a+b)^2\,$ I say ‘$\,a\,$ plus $\,b\,$ (slight pause) squared’, instead of the more cumbersome ‘$\,a\,$ plus $\,b\,$, quantity, squared’.
Shifting Graphs Up/Down/Left/Right April 17, 2020 I made the decision to read ‘e.g.’ aloud as ‘for example’ (instead of saying the letters).
In speaking with ‘math-comfortable’ people who are looking at the mathematics I'm talking about, the difference between the way I voice (say) ‘$\,f(x) + 3\,$’ and ‘$\,f(x+3)\,$’ is almost imperceptible. There is a (very slight) pause after $\,f(x)\,$ in $\,f(x) + 3\,$. There is a (very slight) pause after the opening parenthesis (saying ‘of’) in $\,f(x+3)\,$. In this read-through, however, I chose to over-emphasize these pauses to help people notice the difference.
Horizontal and Vertical Stretching/Shrinking April 19, 2020 I made the decision to read (say) $\,3f(x)\,$ in a couple different ways, to let people know they have a choice:
• $\,3\,$ times $\,f\,$ of $\,x\,$
• $\,3\,$ (very slight pause) $\,f\,$ of $\,x\,$
Given Amplitude, Period, and Phase Shift, Write an Equation April 22, 2020 For this lesson, I chose to always read (say) $\,\sin x\,$ as ‘sine of $\,x\,$’ (using the word ‘of’ which indicates the sine function acting on the input $\,x\,$). However, people frequently omit the word ‘of’, verbalizing it more simply as just ‘sine $\,x\,$’.

Formula for the Length of a Vector April 22, 2020
Writing Quadratic Equations in Standard Form April 24, 2020
Amplitude, Period, and Phase Shift April 24, 2020 The decision was made to read $\,b\,$ as ‘lowercase $\,b\,$’ and $\,B\,$ as ‘uppercase $\,B\,$’ only when they are both being used in the same local discussion.
In this read-through, I read $\,\sin x\,$ as simply ‘sine $\,x\,$’, and $\,\cos x\,$ as simply ‘cosine $\,x\,$’.

Adding and Subtracting Fractions with Variables April 25, 2020
Graphical Interpretations of Sentences Like $\,f(x) = 0\,$ and $\,f(x) > 0\,$ April 26, 2020 For simplicity and brevity, I often say ‘paren’ instead of ‘parenthesis’. In this section, it is very important to distinguish between parentheses and brackets, so I read (say) $\,(1,3]\,$ as ‘open paren, one, comma, three, close bracket’.
