Tens, Ones, and Adventures: Grade 1 Mathematics

By Letters and Devotion

"Tens, Ones, and Adventures: Grade 1 Mathematics" (Grade 1) is the Grade 1 math volume in the Letters & Devotion homeschool print curriculum. It runs 272 pages and contains 70 lessons (Math: 70 lessons), with 282 practice-sheet problems and 138 mastery/unit-check items built directly into the book, plus a full answer key at the back. Every lesson is written for a parent with no teaching background: each one opens with a short script to read aloud, names the specific wrong idea a student is likely to reach for and how to correct it, and closes with a practice sheet that may be copied for household use. Every practice sheet is answer-keyed step by step, not just to a final number. This is a standalone, black-and-white, 272-page paperback printed at 8.5 x 11 in on white paper -- no login, subscription, or additional purchase is required to use it. (The same lessons are also taught aloud by Clara, a built-in AI teacher, at lettersanddevotion.com, with the first 30 days free, for families who want that option; the print book stands on its own without it.)
