STEM Design Challenges [Grades K-8 only]: Houston ISD teachers have project-based learning STEM lessons, referred to as design challenges, accessibel to them for classroom use. The challenges serve to supplement quality teaching with fun projects. The tasks align to high-impact math and science TEKS as well as Career and College Readiness Standards (CCRS), and English Language Proficiency Standards (ELPS). The challenges are presented in an engineering design context and also include differentiation and extension strategies to suit classroom needs.Teachers can find the design challenges for the current grading cycle located in the math and science "Resource" folders on the HUB (For more information, please contact HISD's Curriculum department.). Each of the design challenges contain at least 7 formative assessments to be completed at the end of each stage of the engineering design cycle. These fomative assessments, along with the grading rubrics mentioned below, provide teachers with a variety of assessment options to evaluate students' STEM work.
