This matrix documents the alignment between ABii robot tutor lessons, Common Core / National Standards, and Texas Essential Knowledge and Skills (TEKS) for Kindergarten through Grade 5 in Mathematics and English Language Arts. Each row identifies an ABii lesson title, the national standard number and descriptor, and the aligned Texas TEKS standard number and descriptor. Rows marked N/A or with no direct correlation indicate standards without a matching Texas equivalent. 5th Grade content will be added upon file upload.
