Students model subtracting a fraction from a whole number on a number line by dragging jumps backward to land on the correct difference. This visual approach builds conceptual understanding of mixed subtraction before formal computation. This activity supports TEKS 4.3.E (subtract fractions and whole numbers) and aligns with Common Core 4.NF.B.3.
Skills: fraction subtraction, number line modeling, fraction sense, computation. Grades 4-6.
