"Team Umizoomi: Umi Toy Store" follows Milli, Geo, and Bot as they help Colin recover lost coins so he can buy Sparkle Pup at a toy store in Umi City. The episode reinforces early math and problem-solving skills through counting coins, identifying the number 18, simple addition, coin values, pattern recognition, shape identification, comparing length, and countdowns from 8, 6, and 3. Key vocabulary and concepts include mathematics, currency, patterns, triangles, counting backward, and sequencing. With a playful quest structure, the video supports foundational preschool and kindergarten curriculum goals in number sense, geometry, measurement, and logical thinking. Part of the "Team Umizoomi" series.
