I'm a Maths Star! (Set 1) by Dr Boaz, with a Guide to Problem-solving by Dr Yeap Ban Har. Three picture books that hide a proper maths problem inside a story — The Boy and the Ants, The Girl and the Birthday Problem and The Girl and the Princess.

Each puzzle is worked through step by step using the heuristics taught in the Singapore Maths curriculum — drawing models, working backwards, looking for patterns. Illustrated by Nicodemus Loh and Chang Yit Wah. Published by WS Education, Singapore. Suggested ages 6–12.

Set of 3 softcover books.
