## Number Lines with Missing Numbers

Number lines with missing numbers give students an opportunity to apply some mental math to sequences on a number line. The worksheets below come in different ranges of numbers with larger possible common differences on the worksheets with larger numbers.

The common differences were customized on the following worksheets based on a user request. The possible common differences are: 2, -2, 5, -5, 20, -20, 25, -25, 100 or -100.

## Adding and Subtracting on Number Lines

These adding and subtracting on number lines math worksheets allow students to visualize questions by drawing curved paths to numbers.

The basic process for completing addition and subtraction questions on number lines is: (i) start at 0; (ii) draw a curved line from 0 to the first addend or to the minuend (first number in the problem); (iii) draw a second curved line from the first addend/minuend to the answer by the same amount as the second addend or the subtrahend. For subtraction questions, the curved line will go toward 0 while in addition questions, the curved line will continue to go to the right. For example, 4 + 5 = 9 would be shown on a number line with a curved line starting at 0 and ending at 4. A second curved line would start at 4 and end at 9 which would be a total distance of 5 (the second addend). If the question was 17 - 8 = 9, the first curved line would start at 0 and go to 17. The second curved line would start at 17 and end at 9 which is a total of 8 backwards.
