Do we have a key for those worksheet/assessment?

If anyone know where I can find a sample solution for those worksheets/assessments attached to each lesson, please let me know.

Hi Ms. Jang,

Answers for the assessments should appear at the bottom of those pages in a box surrounded by a blue border, possibly labeled “Answer” or “For teachers only”.

A similar box should appear with worksheet answer keys, usually on the first page of each lesson where students see the links to the worksheets. For example, Unit 1, Lesson 5, bubble 1 should look like this:

If you’re not seeing any of these, it’s likely your account doesn’t have full teacher access. You will then need to fill out this Google form to request access to those resources:
