Again, Essie? [Paperback]

Celebrate diversity, math, and the power of storytelling!

Rafael wants to protect his toys from his little sister, Essie. Gathering materials from around the house, he builds a wall tall enough and wide enough to keep her out. But will it be strong enough? And what does Essie really want? A playful exploration of physical space and geometry, featuring Chicanx (Mexican American) characters and a glossary of Spanish words.

Storytelling Math celebrates children using math in their daily adventures as they play, build, and discover the world around them. Joyful stories and hands-on activities make it easy for kids and their grown-ups to explore everyday math together. Developed in collaboration with math experts at STEM education nonprofit TERC, under a grant from the Heising-Simons Foundation.Rafael wants to keep his toys safe from his rambunctious toddler sister, Essie. What can he do?
Nothing seems to ward off the human tornado that is his little sister. Blocking the doorway with a “no pasar” sign was a bust—Essie can’t read! Maybe he can protect his toys with a barricade. Commandeering an array of household items, Rafael begins constructing “un muro. A wall.” Puzzle boxes, cereal boxes, packing boxes, a portable cooler, and even a roll of toilet paper are pressed into service. Building the wall is not as easy as he thought. Using spatial relations and problem-solving skills, Rafael successfully constructs an impassable and kid-proof obstacle to protect his toys—or has he? Before he knows it, the irrepressible Essie barrels through the wall, and Rafael finally realizes what his sister has been trying to do—it’s not his toys she wants to play with but him. Lacika’s STEM-driven story highlights early math skills, self-directed creative play, and the power of collaboration. Using simplelc)
