English & Maths missions
Explore a picture or passage, work through the idea, then write an answer. Every mission is open. A mistake costs nothing; the worked answer is always available.
For guardians: source, checking and progress
The unit headings and order match the publisher's Primary Mathematics Learner's Book 4 (ISBN 9781108745291) and Primary English Learner's Book 4 (ISBN 9781108759991). The explanations, passage, diagrams, questions and projects are original Kidemy practice aligned to those headings. They are not reproductions of, or a substitute for, every textbook exercise.
Typed answers are checked against listed answer keys, so a different valid wording may need a guardian or teacher’s review. The speaking tasks are written rehearsals, not automatic speech assessment. Projects also need a guardian or teacher check. Completed answers stay completed after a retry. Progress is saved in this browser only.
