Questions from international schools
Do you sell to schools outside North America?
Yes. The lessons are PDFs, so there is nothing to ship. Pay by card in US dollars, at checkout or from an invoice we email you (ask for a pro-forma invoice if your school needs one first). We can't take bank transfers from outside Canada yet. Invoices come from ZalaStack Inc., a Canadian company, and we accept purchase orders.
Is any tax added to the invoice?
No Canadian tax is added for schools outside Canada. If your country taxes imported services, for example VAT by reverse charge or a withholding tax, your finance office handles it the usual way.
We teach the British or Cambridge curriculum. Which units fit our Year 5?
Year 5 and Cambridge Primary Stage 5 are the same age as US Grade 4 (ages 9 to 10), so start with our Grade 4 units. The table on the International schools page lists every year group, and we map units to Cambridge stage objectives on request.
Does Fieldbook work in an IB PYP school?
Yes, as the science inside a unit of inquiry. Every unit starts from a real question students can test, and the International schools page shows which transdisciplinary theme each unit usually fits.
Our school is in a hot country. Do the lessons still work?
Almost all of them. Materials are everyday items, measured in metric. The two winter units need snow or a freezer, and a few lessons open with a Canadian example such as winter weather; teachers swap in a local example or skip those.
