Classroom Guide: Modeling Addition & Subtraction
Visualizing operations on a number line helps elementary students grasp place value jumps, mental math decompositions, and distance concepts.
1.Forward Jumps (Addition): Start at a base number (e.g. 35) and jump forward in tens and ones (+10, +5) to reach sums.
2.Backward Jumps (Subtraction): Model subtraction by hopping backward from minuends.
3.Open Number Lines: Use custom ranges to allow flexible student mental math strategies.
