Why we made this

One teacher. One scientist.

Vaishali Gupta spent twenty years in education watching bright children decide they were “bad at science”, usually before they were seven, and usually after being handed a worksheet.

The problem was never ability. It was that science arrived as a set of answers to memorise, instead of a question worth chasing.

So she built what she wanted for her own classroom: activities that need no lab, no screen, and no expertise from the adult in the room.

Every order funds the SLATE Program. 5% of what you spend puts learning materials into the hands of children who would otherwise go without.

Before you ask

Questions parents actually send us

Is this for one child or a family?
Either. It covers ages 3 to 10, so one child grows through it over years, or siblings use different levels at the same time.
Where do we start?
With the Level 1 products if your child is 3 to 6, Level 2 for 6 to 8, Level 3 for 8 and up. Keep the rest for later.
