Playtime event for the whole school – Includes Teacher PD

Our PARTS school incursion program is a great way to introduce the concept of ‘loose parts’ play to your school community.

Most effective within a collaborative, inclusive and rights-based educational setting, Green Hat Workshop’s PARTS incursion program cuts sedentary behaviour, improves creativity, encourages mixed age, mixed gender, self-directed, imaginative, open-ended play, a growth mindset and interpersonal skill development, encourages rule and game making, as well as the consolidation of STEM learning and creative problem solving in real world contexts, all while supporting cognitive processes, co-ordination and positive school yard social interactions.

PARTS by Green Hat Workshop inspires a dynamic alternative to sports and fixed play equipment in the school yard and our reflective practice, child-centered approach and structured implementation ensures PARTS can have an ongoing value to your school community.

Our incursion includes a one hour teacher briefing and is staffed by a trained and experienced play-worker, covered by our own insurance and engineered to provide an optimum ‘loose parts’ play experience for your entire school student population, all ages, all at once.

How we work

About our Pedagogy

Inspired by Melbourne’s progressive schooling movement of the 1960s and influenced by the field of Playwork, Green Hat Workshop emphasise a play-based, participant led, activity model, where possible. We create and provide resources and environments that first and foremost authentically engage participants and engender fun and play.

We acknowledge that we are in partnership with our participants during our workshops, enabling and encouraging their natural instinct to play with pattern, aesthetics, order and symmetry, representations of narrative and the world around them, shelter & cubby building and role play as well as comparison and intrinsic challenge.

Green Hat Workshop’s approach is to work within existing school cultures and public spaces to empower natural curiosity and creativity in all ages, with as few instructions and rules as possible, thereby engaging all participants at their own level of cognitive and physical ability, be they adult or child, neurotypical or diverse.

We do not write programs that emphasise content or specify a valued outcome but rather value authentic participant-lead programs that provide environments optimum for shared creativity.

Green Hat Workshop provide simple, abundant, impermanent resources where possible, as we believe this encourages individuals to experiment, share and explore.

We believe:

  • Engagement comes first
  • We think our way into maturity and successful skill adoption
  • Children come to us with knowledge
  • Self-directed play is the best way to learn
  • Humans learn when they are ready and cannot be compelled to do so
  • The goal of every teacher is to become obsolete*



PLANKS are dynamic building blocks designed to inspire creative minds. Identical in size and shape, and cut precisely from 100% New Zealand plantation pine, PLANKS are specifically proportioned so that,with the help of gravity and a little imagination, you can build, boats, castles, animals and robots… or even a spiralling staircase to the moon. Totally inclusive, PLANKS encourage a wonderful mix of creativity and skill, social development and imagination.

The flexibility of our PLANKS’ rectangular prism shape and Green Hat Workshop’s philosophy of self directed, play-based learning, provides opportunities for all abilities to participate and to challenge themselves at their own level, enabling participants to simply stack towers of impressive height or to create sophisticated cantilever bridges, 3D shapes and more.

Green Hat PLANKS Workshops offer an abundance of PLANKS, promoting the opportunity to share and celebrate diverse expressions of creativity, Mathematics, Engineering, interpersonal skills and resilience.

Ainslie Lamb-McCallum

Yet again, your PLANKS workshop has been one of the most successful family nights our school has run.
We had parents, students and staff all engaged in hands on learning across many curriculum areas.
The rich language associated with STEAM was being used throughout.

As a middle school group (15 year olds) we have participated in Green Hat Workshop PLANKS building over the past 4 years.  Cameron catered for our more capable students and made modifications to enable our high needs students to participate. It is an activity that our group of students look forward to each year.

Patricia Glenane
Ballarat Specialist School
We all had a fantastic time, students were so engaged and excited by the possibilities the PLANKS provided them. It was great to see every student participating in their own way and learning from each other.
The whole process has been very straightforward and professional. Congratulations on your provision of such a great incursion.
Deb Nugent

It was our largest Family Maths Night for years and the parents took construction to another level with their children.

About the role of Facilitator

Artist, science communicator, assistant, demonstrator, teacher, playworker and psychologist all rolled into one, Facilitation at Green Hat Workshop can be equal parts understanding curriculum, Playwork theory and cognitive development. Safety and the independence of the workshop participant is the priority, in some situations however Facilitators scaffold potential uses for resources, create environments where creative challenges are accessible for all ages, support participants’ own ideas, manage hazards and help out when needed, preferably without directing or controlling. We provide opportunities for creative expression linked to practical learning and within the constraints of timetable and environments of our clients and their institutions.
