Students build fluency dividing whole numbers by fractions using dynamic interactive flashcards, with number line models supporting each problem. Learners flip through cards to practice division problems, reinforcing procedural fluency alongside conceptual understanding. This activity supports TEKS 5.3.J (divide whole numbers and fractions) and aligns with Common Core 5.NF.B.7.
Skills: fraction division, number line modeling, computation fluency, number sense. Grades 5-8.
