This workbook introduces children to addition and subtraction using number lines for numbers 0 to 20. The number line serves as a visual aid, with sequential numbers arranged to demonstrate the distances between them. Children learn to navigate this line, moving a marker to perform addition and subtraction, thereby grasping mathematical concepts interactively. The book incorporates practical examples and exercises to solidify understanding.

This workbook is designed as an educational tool for young learners to grasp fundamental arithmetic operations. The use of number lines provides a visual and interactive method for understanding addition and subtraction, which is particularly beneficial for children who are new to these concepts. The inclusion of practical examples and exercises aims to reinforce learning and build confidence in mathematical abilities.
