Amazing resources which have really helped our school be more confident in using the outdoor space to enhance the children's learning. Great, fun, easy to follow lesson plans, which link directly to the key objectives!

The Alfresco planning hub is a fantastic resources with lesson that are easy to pick up and teach. I use them both as full lesson, lesson starters and intervention session for an LSA. Would highly recommend.

I am a member of the Planning Hub and I love the variety of lessons provided. Most lessons need only simple materials that I usually already have on hand. I love taking my students out with these lessons.

Brilliant resources, easy to follow and adapt for learners, clear progression!

The online planning hub is a lifesaver. I teach in KS1 and the children always ask when we are going outside and parents always say how excited the children are about their outdoor learning. It is exactly what I was looking for and have now been using it for several years. Thank you for such a brilliant resource!
