Mathematics

Digitot, the Number Realm companion Curio

Companion: Digitot. A small fish whose scales are etched with tally marks. It counts its own bubbles as it swims.

Purpose

Math word problems and computation, answered in whichever format fits the question — typed numbers, a fraction's numerator and denominator, or a time picker for elapsed-time problems.

The science

Just like spelling, shaky number facts eat into the working memory a child needs for the actual reasoning in a word problem. Building procedural fluency — instant recall of facts and operations — is what lets a child spend their thinking on the structure of a problem instead of the arithmetic inside it. The timed, repeated format is deliberately built for this: it's spaced retrieval practice for the number sense that everything later in math is built on top of.
