With Electro "At School," children playfully learn to observe carefully, make connections, and remember. What do you see in the classroom, and which objects are musical instruments? Look closely, think logically, learn colors, letters, and much more! Playing stimulates a child's development and curiosity. Fun now, useful for later! How Electro works: 1. Choose a card and read the assignment. 2. Do you know which answers are correct? Touch the black answer dot with the tip of the pen. Hold the pen upright and gently press the tip. 3. If the answer is correct, you'll hear a tune and the light will turn on. Don't see the light or hear any sound? Try again! Sometimes more than one answer can be correct. Features: • Recommended age: 3+ years • More than 40+ questions • Wonderpen uses 2x 1.5V AG3 (LR41)
