Lengthy Addition

Worksheet Description

This worksheet is a mathematical resource designed to help students practice addition using number lines. It contains three number lines each ranging from 0 to 20, with different addition problems presented above each one: “8+8”, “10+8”, and “5+9”. Students are expected to use the number lines to count forwards to find the sum of the numbers given in each problem. For each addition problem, there is an allocated space for the student to write the final answer.

The purpose of this worksheet is to teach students how to use number lines as a tool for visualizing and solving addition problems. It extends the range of numbers up to 20 to challenge students with larger sums. This practice helps students to understand the concept of addition as a sequential increase and to become more comfortable with counting in increments. By repeatedly using number lines for addition, students can develop a more intuitive grasp of number relationships and enhance their mental arithmetic skills.
