It never solves the page

Encorn is for extra practice. It writes new problems of the same type and never gives the answers to the page your child is working on. Each sheet has two easier problems, one at the same level and two harder.

Steps you can explain out loud

Every problem comes with short steps for the parent. The answer stays hidden until you tap it. Numeric answers are recomputed on the device and labelled Answer checked. Answers that cannot be recomputed say so.

A tree that fills up

Each finished problem puts an acorn into a hole on Corna's tree. Every exercise type is a branch, so one look shows which types were practiced and which are still thin.
