MATATAG Mastery Diagnostic Rubric & Remediation Tips
Performance Level Observed Student Understanding Recommended Teacher/Tutor Next Steps
Mastery (25-28 pts) Consistently adds ones first, then tens; writes digits neatly in their proper place value columns without confusion. Introduce vertical addition with 3 addends or transition to early regrouping concepts (sums crossing 10).
Developing (19-24 pts) Solves most 2-digit additions correctly but occasionally starts from the tens column or makes minor single-digit slips. Reinforce the mantra: "Start from the right! Add Ones first, Tens second." Use arrow visual prompts.
Needs Support (<19 pts) Misaligns single-digit numbers under the tens column or adds across columns diagonally. Use a physical place value mat with green (Tens) and yellow (Ones) column slots and bundled sticks.
