Unidad Educativa Particular Alborada is a K-12 private school in Cuenca, Ecuador, which challenges students to develop a greater understanding of the world. Challenge-Based Learning (CBL) is an adaptive learning framework, encouraging students to solve real-world problems and integrating High-Impact Teaching (HIT). We piloted a CBL curriculum for 4th, 5th, and 6th grade students. We assessed both teacher and student attitudes to our CBL lessons examining the feasibility of continuing to teach it. Also, we provided sample CBL lesson plans and a set of recommendations for the Alborada faculty in regards to implementing CBL
