Second-graders in Jackie Oquendo’s class at Susan E. Wiley Elementary School are practicing their math fluency in fun ways. The classroom divides into different math centers and rotates through different stations to hone their addition and subtraction skills. In one station, students used dice, the students tested their fluency with math word problems, while another station used popsicle sticks to work on different placement values. Students also played math games using their Chromebooks.
