Introductory Scratch-based curriculum for elementary-aged children recommendations?

Hello,

I am looking for advice and feedback, let alone knowledge of, an introductory Scratch-based curriculum for

elementary-aged children. Settings to implement would be

out-of-school & after-school elective and home schooling environments.

Does anyone have a recommendation(s)?

I appear to see more focus on middle- and high-school focused currciula,

where as the younger ages are more exploratory, experienced focused.

Activity-based explorations are great and I am trying those,

but would love to see some foundational basics built upon through

their exploration activities, apprioriate for the younger ages.

Do you have any favorite experiences or recommendations for

this age group? Maybe a check list or itemized goals the educator/instructor sets

for each exploration, to build the individual's tool set to tackle the more

complicated activities/explorations/projects?

Thank you for your advice and feedback!
