Two early-numeracy skills, one routine

Comparing quantities and knowing what comes next are two of the earliest number-sense skills, and both appear on kindergarten and first-grade screeners because they predict later arithmetic. "Which is more?" asks students to judge magnitude directly — and this tool uses the same grouped dot arrangements as the subitizing routine, with matched dot sizes on both sides, so the answer can't be read from density and students must reason about quantity. "Missing number" builds the mental number line: knowing that 7 comes right after 6, or that a skip-counting pattern continues 2, 4, 6, is the forward-and-backward flexibility that fluent counting depends on. Both tasks are quick, discussion-friendly, and screener-aligned. Flash, give think time, and ask how students knew — "how did you know without counting all of them?" is where the number sense shows itself.
