Children's toys have some gross eye-hand coordination items that people might enjoy between ACL 3.6 and 4.2.
When a visual design is added to manipulatives, it usually raises the ACL score because in ACL 3 attention is not captured by the shape or pattern.
The Pipe Tree becomes ACL 4.0 because it has patterns to follow. If you eliminate the pattern you can take them down to ACL 3.2. This activity may go as high up as ACL 5.8 if a three-dimensional design is used. Further development will need to be completed so local materials can be sourced to reduce shipping costs. Men who have used their hands with manual labor will be more attracted to this task.
