This article describes how the Just-in-Time Teaching (JiTT) warm-up exercises were successfully adopted into a college-level physics course as a teaching tool. Students were found to be more engaged in lectures after completing the warm-up assignments. The results from anonymous student surveys showed their overwhelming appreciation for the exercises. The survey results also demonstrated that male and female students differed significantly on whether they felt the assignments were helpful in their understanding of the course material. In addition, student exam scores have improved since the warm-up exercises were adopted.
