Counting 0–20

English prompts map to Spanish words from cero through veinte—your first dedicated counting deck before tens and larger figures.

Tens 10–200

Step through tens and decade jumps in Spanish while English keeps the prompt side familiar; small-number review stops earlier ranges from fading.

Mixed numbers 0–200

Random-style values through 200 force flexible Spanish recall: ones, teens, and tens in one deck so you are not only comfortable with “clean” decades.

Hundreds 100–2,000

Hundred-steps to 2,000 in Spanish: learn how “cien/ciento” and larger hundred anchors combine with leftovers you already practiced in earlier levels.

Mixed numbers 0–2,000

Unstructured practice to 2,000: jump between small figures, decades, and hundred-based totals so Spanish number reading matches everyday unpredictability.

Thousands to a million

Large-number scaffolding in Spanish: thousands through a million, with English cues so you focus on how Spanish stacks “mil” and six-digit shapes.

Full range to a million

Capstone deck: every magnitude you studied—from single digits through a million—appears in unpredictable order so Spanish number production stays reliable under pressure.
