“Resources right where I need them, when I need them – not stuck at the side of a room in heavy wooden furniture.”
Michael Williams, Headteacher
STORAGE FOR TODAY’S TEACHING Create easy access to learning resources
Nothing stands still in teaching, and we know that your space is at a premium. Callero makes your learning environment work better.
Meeting the needs of every child in your class means differentiated resources.
To achieve mastery, abstract learning starts with concrete manipulatives –particularly in maths. Some students are ready to move on faster than others. Callero storage on wheels gives you exactly what you need, wherever you need it in the learning area: from students needing the additional stretch to those struggling to meet expectations.
With demands on phonics and literacy greater than ever before, create easy access to everything you need.
Foam letters, digraph magnets, flashcards, overlays, reading rulers, phonics mats: they all need separate storage. Having a tray system in place for each one reduces lesson set-up time and means students can collect what they need, without an adult setting up in advance. For inspiration, we’ve also designed our units so that books and other learning resources can be displayed on top to draw students in.
Callero is an organic storage system that grows as your teaching needs change.
Our modular Callero Custom wall units let you build up or build across, giving you the smallest footprint for the largest storage capacity. At Gratnells, we have more options than any other school range and the most flexible solutions for limited spaces.

Every student’s needs are different; let Callero help
In today’s inclusive learning environment, it’s essential to provide resources that support those with neurodiverse needs.
Task boards and timers, writing slopes and overlays, fine motor materials and sensory supports – all these resources need storage that allows swift access to meet your student’s needs. With this in mind, Callero offers different sized trays for smaller and larger items.
Callero also means agility for small group working
Until the learning has started, we don’t always know who needs support for an activity or which resources will help. With ergonomic handles, castors and a structure up to 30% lighter than wooden equivalents, students can move Callero units to a table or carpet area. It gives them easy access to everything they need to support their learning activity.
Students can be active in setting up their own group work
We know how important collaboration and independence are for students with SEND. With lightweight, mobile Callero units and StopSafe tray runners, it’s safe and easy to move resources to where they are needed, without adult support. Our lift-toremove system uses clips to only allow trays to be pulled out to a certain length. Should the tray need to be totally removed from the storage unit at any time, a simple upwards tilt will allow it to be fully withdrawn. Our units also help build a sense of pride in group or paired work. Their flat magnetic sides allow you to display visual instructions and mean that work in progress or completed projects can easily be affixed, transforming the space into a project centre.
Trays make pre-learning and overlearning simpler
Opportunities for consolidation are vital for students with EAL or additional needs. Gratnells trays are ideal for setting up and storing pre-learning and overlearning activities for individuals, pairs or groups.
“Easy access to resources allows the children to make their own learning choices.”
