While many wooden blocks use harvested timber, PlanToys uses reclaimed rubberwood from trees that no longer produce latex. This makes the Unit Blocks more sustainable than standard FSC-certified hardwood sets that require new tree harvesting.
How to use it
- Encourage your child to build vertically and horizontally to explore balance.
- Mix these unit blocks with other toys like animal figures or toy cars to create landscapes.
- Use the blocks to teach basic math concepts like addition and subtraction through physical representation.
- Store in a dry, indoor environment to maintain the wood's integrity.
