Question: An elementary school student has 5 red blocks, 4 blue blocks, and 3 green blocks—blocks of the same color are indistinguishable. If the student stacks one block per day over 12 days to build a tower, in how many different color sequences can the blocks be stacked?

**How Many Color Sequences Can Young Learners Create When Stacking 12 Identical Blocks in 3 Distinct Colors?** Curious minds everywhere are exploring how simple materials spark creativity and pattern complexity—especially through hands-on play. A classic question combining basic math, probability, and early STEM thinking is: *If a student stacks 5 red, 4 blue, and 3 green blocks—each color group indistinguishable—over 12 days, how many unique color sequences emerge?* This isn’t just playful math; it’s a real-world example of permutations with repetition, relevant to educators, parents, and anyone fascinated by learning through tactile experiences. The challenge lies in how few distinct sequences arise despite numerous stacking orders, offering rich insights into combinatorics and counting principles. --- **The Rising Interest in Hands-On Learning and Early Math**
