This title is part of Bug Club, the first whole-school reading programme that joins books with an online reading world to teach today's children to read. In this Green-B level Silly Jack book: Jack’s mum is not happy when he swaps both their cows for a harp, a bee, and some dancing mice – he should have sold them for gold! When the king decrees that he will give Gold-to anyone who can get the queen to dance, Jack decides to go for it!
