Sisters All the Time

Join half-sisters Mari and Luz in an exploration of time and estimation, because STEAM is everywhere and for everyone!

Part of STEAMWORKS, a series of fiction picture books for ages 4-7 that relate science, technology, engineering, arts, and math (STEAM) to kids’ everyday lives.

Mari and Luz are a special kind of sister: half sisters! They share the same Papi but have different moms, so they spend only weekends together. When Luz’s mom is running late, the girls are determined to make the most of their extra time–planning their activities, estimating how long each will take, and diving in. But time runs out too soon, and Mari feels sad. Luz reminds her that they’re sisters ALL the time, even if they can only be together some of the time.

Extend the learning beyond the story with expertly crafted back matter, including additional information about telling time and fun STEAM activities.

STEAMWORKS features children of all backgrounds and abilities using scientific and mathematical thinking to solve everyday problems and answer questions that matter to them. Playful stories and extension activities ignite excitement for science, technology, engineering, arts, and math (STEAM) and empower children as thinkers, problem solvers, and innovators.

STEAMWORKS picture books are also available in Spanish.
