Lost Cities is a game that offers opportunities for meaningful practice at varying levels of expertise—provided strategies are taught in meaningful ways. In particular, it offers a motivating context for practicing skip counting, making tens, and flexible re-grouping for adding two and three-digit numbers.
Sleeping Queens can offer meaningful practice with regrouping to add, recognizing equality, and dividing by two and three. It can be played in a way that makes it accessible for children in K-3 or challenging for children in Grades 4-6 (and beyond). It can also be adapted for play with a traditional deck of cards.
