1.4-in-1 Math Skill Coverage (Addition to Division)Comprehensive set includes flash cards for 4 core math operations: addition (0-20), subtraction (0-20), multiplication (1-12), and division (1-12). Each card features large, easy-to-read numbers and clear equations, helping toddlers and kids build foundational math skills step-by-step—no need for multiple separate kits. 2.Interactive Board for Hands-On LearningComes with a durable, dry-erase practice board (with included marker) that lets kids write down answers, erase mistakes, and retry freely. The board’s smooth surface is easy to clean, and its compact size (fits in the kit’s storage bag) encourages active participation—turns passive flashcard reading into engaging, hands-on practice. 3.Portable Design for On-the-Go LearningAll components (flash cards, board, marker, eraser) are packed in a lightweight, zippered storage bag—perfect for travel (car rides, planes), home practice, classroom activities, or after-school tutoring. The cards are made of thick, tear-resistant paper (suitable for toddlers’ small hands) and won’t bend or wear easily with frequent use. 4.Kid-Friendly & Adult-Guided LearningFlash cards use colorful, kid-approved designs (no overwhelming text) to keep toddlers focused, while the practice board lets parents/teachers guide learning—easily track progress, correct errors, and turn practice into a fun game (e.g., “who solves 5 cards first?”). Suitable for independent play (older kids) or guided sessions (toddlers). 5.Durable & Reusable for Long-Term UseThickened flash cards (2x more durable than standard paper cards) resist spills, tears, and creases—safe for toddlers to handle. The dry-erase board and marker are reusable (marker washes off easily), eliminating waste from disposable worksheets. A cost-effective tool that grows with kids, from learning basic addition to mastering division.
