We elected to take our time working through Lesson 86, starting off by learning about the strongest acids and bases in the world:

Next, we worked through a set of class notes and practice problems pictured below (the Lesson 86 PowerPoint is available for reference), connecting molar concentration of H+ or OH- with pH.

After the notes, students transitioned to the Lesson 86 section of the Lessons 85-87 packet.

The next day, we began class by practicing the skill of calculating pH from molarity and molarity from pH. Students were reminded that Google Chrome can be used as a calculator. Desmos.com offers a nice web-based scientific calculator as well. Students had the remainder of class to work through the Lesson 86 section of the Lessons 85-87 packet.
