Providing opportunities for elementary students to engage with enduring social issues, such as houselessness, is essential in preparing informed, engaged, and social justice-oriented citizens. This article draws from the following standards: (1) C3 Framework for Social Studies Standards that center inquiry; (2) Learning for Justice's Social Justice Standards that foster antibias attitudes and collective social action; and (3) National Council of Teachers of Mathematics standards guiding mathematics concepts and skills. The authors propose a sample integrated lesson for teaching about houselessness with early childhood learners (grades K-2), centering mathematics as a tool for examining the needs of children, individuals, and families living in shelters.
