Grade 2 Mathematics · Answer Key

Arriving · Written · waiting for a credentialed teacher's review and signature before it can sell

This Answer Key goes with the Grade 2 Mathematics kit. For each of the 51 lessons it gives the answers to the Student Edition practice, the Workbook set and the Assessment Book quiz, side by side, so the adult can check a whole lesson from one page.

Each unit ends with the answers to Math Talk, Show What You Know, the unit test and the Make It! rubric, and the midterm and final are here too. Strategy items show one worked method, such as making a ten, partial sums or counting up on an open number line, and note when another method from the book is just as good. Open items say what a strong answer includes.

The key is for the adult, not the child. It teaches nothing new; it matches each book exactly.
