The Botany Leaf Cabinet with Insets (B090) is a classic sensorial-to-botany bridge material featuring wooden insets in a range of leaf shapes, suitable for toddler through lower elementary depending on how the lesson is framed. Toddlers and primary children use it for shape matching and refinement of fine motor control, while older children connect the insets to botanical classification and leaf morphology work. Having it in your classroom means you can pull it across multiple levels without replacing the material, making it an unusually versatile investment.
