What are PLANKS?

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.

How do Incursions look?


No bus hire, entry fees or permission slips –  easy to organise.

Green Hat Workshop incursions are facilitated by  trained educators and employ and play-based, self-directed approach to STEM-play. In a PLANKS incursion we can cater for up to 100 participants at once to emphasise an experience of  collaborative creativity.

Our Education Manager will co-create a program to fit your planning, student interests or topic. Our PLANKS are open ended and adaptable to any HASS, STEM, interpersonal skills, co-operative or student well-being needs you may require.

Workshops may be delivered as:

  • A single session with up to 100 participants of all ages,
  • A full day with students and then a family evening,
  • A “drop-in” activity for a school-wide event,
  • A sustainable and ongoing whole school STEM-Play resource

At Green Hat Workshop we pride ourselves on running

  • the most engaging school incursion program,
  • for the largest number of students in one session,
  • for the widest range of abilities
  • for the most extended length of time.

The most valuable aspect of each workshop is the period of time where participants are engaged in free, self-directed play. During this time our Facilitators work hard to open up the potential learning in the activity through demonstration, question and prompted reflection.

Following are the focus and design of some of the workshops we have facilitated.

  • PARENT MATHEMATICS EVENINGS – Whole Family open ended play

A series of workshops beginning after morning recess, then an hour of open structural play in the evening with parents; sometimes with a presentation introduction or conclusive reflection that outlines the value of open ended block play in Mathematical Development.

  •  STEM / STEAM & INTERPERSONAL SKILLS  -Science, Technology, Engineering, Arts & Mathematics
Introduction and examples of forces and movement within the activity, warm up challenges, Free build, Reflection, Clean up.
  • HASS – Humanities and Social Studies
– A full day of city and infrastructure design with a final city building workshop.
– A conclusion to a unit of work on geography and history using the PLANKS to recreate famous historical buildings and land-marks from around the world.
  • Creative Celebration

 Short intro and long build. Just for fun.. and education. Often at the end of the school year, at a school celebration, camp or special day.

What Teachers say...

The Cheshire staff were so impressed with you and your approach to our students and we would like for you to come to our school next term and potentially each term after.

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.

It was our largest Family Maths Night for years and the parents took construction to another level with their children.
Thank you for being so accommodating to our needs and so easy to work with.

I have no hesitation in recommending Green Hat Workshop and PLANKS if what you are looking for is a creative, intellectual challenge that can readily incorporate team work.
