Helpful is some ways, but misleading in others.
In the Guided Practice section after the second video, the instructions are: "Define the variables and translate the following expressions into inequalities."
The first example requires an equation, not an inequality:
"a) Jose took 3 train trips in a day, some of which cost $2.75 and some of which cost $3.95. His total cost was $9.45." For students just learning about equations and inequalities, this can be very confusing.
Also, in the Practice section, the instructions read: For 1-10, define the variables and translate the following expressions into equations." and yet some of the problems require inequalities. Again, confusing and not precise. Having students know and understand the power of vocabulary and precise language is key to their really understanding algebra!
