Using Number Lines to Add and Subtract Decimals Crossing One WORKSHEET DESCRIPTION
This worksheet makes use of number lines as an aid for pupils beginning to add and subtract decimals over 1. Learners will also be required to make use of their knowledge of complements to 1, 10 and 100 and mental addition and subtraction of decimals within one.

Both sections begin with an example for students to follow, and the scaffolding decreases steadily enabling your students to work through independently. In each section there are 4 questions made up of decimals with 1 decimal place and 4 questions where the decimals have 2 decimal places.
