What your child builds

A shopping trip for Sprout's picnic, with a budget and a shopping list. At each of three stalls there are two offers: buy one at a time, or a bigger bag, pack or "buy 2, get 1 free". A magnifying glass works out what singles would cost for the whole list. Buy too big and you pay for extras you didn't need; buy to the need and you keep the most coins, and become a Deal Detective.

Three editions: A picnic in the park, on a Dubai beach or at Juhu Beach, with apples, oranges or bananas on the list.

For grown-ups

A smarter shopper, before the next shopping trip. Every pack ends with a section for you: what your child learned in each build, and questions to keep the conversation going.

“Have you seen a ‘big pack’ or ‘buy one, get one free’ in a shop? Was it a good buy for us?”

“If we only need 4, why might a bag of 6 still cost us more?”

“What could we do with extras, so they aren't wasted?”
