Assess students' ability to perform simple addition by combining two small groups of objects or numerals, with sums up to 10. Include pictorial, verbal, and symbolic items that require counting, joining groups, and identifying totals; emphasize conceptual understanding, use of manipulatives, and strategies such as counting on and recognizing part‑part‑whole relationships. Appropriate for Pre-K–Grade 2 as a formative check of early addition skills.
