In this unit, students explore percents in depth. They begin with understanding percents as a part/whole ratio, comparing a given part to 100, which represents the original whole. In this way, the study of percent is linked to the study of proportionality, one of the big mathematical ideas of middle school mathematics.
The Teacher Guide is designed to provide background information on the mathematics being taught in this unit, the learning environment, mathematical communication and differentiated instruction. Also included:
Esperanza thought she'd always live a privileged life on her family's ranch in Mexico. She'd always have fancy dresses, a beautiful home filled with servants, and Mama, Papa, and Abuelita to care for her. But a sudden tragedy forces Esperanza and Mama to flee to California and settle in a Mexican farm labor camp. Esperanza isn't ready for the hard work, financial struggles brought on by the Great Depression, or lack of acceptance she now faces. When Mama gets sick and a strike for better working conditions threatens to uproot their new life, Esperanza must find a way to rise above her diffi

The Student Mathematician’s Journal allows students to explore simulated or real-life problems and help them to think, write, and read like mathematicians. It encourages students to reflect on what they have learned in each lesson, think deeply about mathematics, and communicate in writing on worksheets.
