Mathematics
Ezra used a number line to add numbers in the teens and twenties, practicing how addition changes a starting number as he moved forward. He learned to connect a written addition problem with movement along a visual sequence of numbers. This supported his understanding of counting on and helped him see how larger numbers can be added step by step. Using the number line also gave Ezra a way to check and explain his calculations.
Tips
Tips Turn the number line into a playful path: have Ezra choose a starting number, draw or make a jump for the amount being added, and say each landing number aloud. Try a floor number line with paper markers so he can physically step through addition problems, then invite him to invent a story problem about the jumps. To extend his learning, compare different jump patterns that reach the same answer and discuss how the number line shows that addition combines amounts.
