MATATAG Mental Math Speed & Accuracy Diagnostic Rubric
Performance Level Observed Speed & Accuracy Recommended Teacher/Tutor Next Steps
Speed Master (54-60 pts, <75s) Instantly recalls doubles and tens facts without finger counting; computes sums smoothly in seconds. Advance to adding 2-digit numbers with tens and ones mentally (e.g., 34 + 23 mental compensation).
Building Fluency (42-53 pts, 75-120s) Applies doubles and decade shortcuts well, but pauses on bridge-to-10 facts (e.g. 8 + 5). Practice "Ten-Frame Flash" cards: flash 8 dots, flash 5 dots, have the student visualize moving 2 to complete 10.
Developing Recall (<42 pts or >120s) Relies heavily on counting on fingers by ones (1, 2, 3...) for every problem. Anchor doubles songs (5 + 5 = 10, 6 + 6 = 12) and practice counting up by tens (10, 20, 30...) to build automaticity.
