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. Advance to 3-digit vertical addition or introduce horizontal mental math decomposition drills.
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 core mantra: "Start from the right! Add Ones first, Tens second."
Needs Support (<19 pts) Misaligns single-digit numbers under the tens column or adds across columns diagonally. Use a physical place value mat with blue (Tens) and red (Ones) column slots and bundled sticks.
