Students model adding and subtracting fractions on a number line by dragging fractional jumps to land on the correct sum or difference. This visual approach builds conceptual understanding of fraction operations before formal computation. This activity supports TEKS 5.3.H (add and subtract fractions) and aligns with Common Core 5.NF.A.1.
Skills: fraction operations, number line modeling, fraction sense, computation. Grades 5-8.
