Revisiting puzzles?

I looked at the data/progress for how well my students did for the first plugged in lesson for course B. Some of my students completed several of the puzzles but they used too many blocks. Should I go back with them and work through the puzzles with them since its the first plugged lesson or should I just let them learn as they go?

Great question @kscherrick!

This is a great opportunity to challenge students to write more efficient code. Depending on the amount of time you have, you can have the students revisit their own puzzles, participate in pair programming, revisit as a class, or simply highlight where students can view their block count in the site (below the directions and above the work space).

I would love to know which strategy you use and how it works!
