STEM Challenges, Jr. Learning Cards offer a convenient way for grades PK-1 to incorporate STEM activities into their curriculum. Each box contains 30 full-color cards that utilize common materials to encourage students to explore essential scientific concepts like plants, animals, insects, weather, transportation and more. Cards provide students an opportunity to exercise their creativity, build things like a seed carrier, squirrel-proof bird feeder, or igloo, and learn with visually-appealing picture directions. Sturdy and durable, these cards are ideal for individual or whole-class instruction, early finishers, centers, or indoor activities.
