Four dollars of kindergarten maths that actually maps to what a teacher will cover. Silver Dolphin built the Ready to Learn series against the Common Core State Standards and had each grade level vetted by early education specialists, so the sequence here is the sequence a child will meet in class rather than a random pile of exercises.

It runs counting from one to twenty, simple addition and subtraction, number patterns, shape recognition and first measurement, across 64 full colour illustrated pages. There is an answer key at the back, which matters more than it sounds: it means a parent can check work without having to re-teach themselves anything.

It finishes with a Certificate of Achievement, and any parent who has watched a five year old carry a certificate around the house for a week knows why that page earns its place. Ideal for the summer gap, for pre kindergarten preparation, or for the child who wants more than school is giving them.
