About This

• WHAT'S HIDDEN INSIDE? OPEN AND COUNT! – Every card hides a secret — a hippo's mouth full of toothbrushes, a magic cave with surprises inside, a treasure chest waiting to be opened. Kids peel back each card to reveal what's hiding, then count what they find. The thrill of the reveal makes every number unforgettable.
• COUNT 1 TO 20 IN ENGLISH AND SPANISH – Go beyond basic counting with bilingual number learning across all 20 cards. Children build early math and dual-language recognition simultaneously, making this an ideal tool for bilingual households and classrooms.
• JOIN MARJI ON A NUMBER HUNT ADVENTURE – Follow Marji — the math-obsessed Kidrox Squad explorer who counts everything from stars to jellybeans — as she hunts for hidden objects in each location. Story-driven play keeps children engaged far longer than static flashcards.
• 20 HIGH-QUALITY CARDS, AGES 3+ – Full number coverage from 1 to 20 on premium-print cards, designed for little hands. Durable card stock withstands repeated unfolding and refolding through daily play sessions.
• KIDROX SQUAD SERIES – Part of our growing toddler learning collection, featuring familiar characters across every set to help children build confidence while exploring new topics like letters, professions, and more. Collect them all to expand their learning journey.
