Mathematics
This Grade 1 mathematics worksheet helps students find 1 more, 1 less, 10 more, and 10 less than a given number. It includes 13 questions: 9 multiple-choice items and 4 fill-in-the-blank items using numbers such as 5, 22, 38, 66, 75, and 96. Students practise identifying how a number changes when one is added or subtracted and how its value changes by one ten. The worksheet supports early number-sense development and helps students apply counting and place-value patterns to one- and two-digit numbers. The mix of selected-response and written-response questions gives teachers a quick way to check whether students can distinguish changes of 1 from changes of 10. This free printable worksheet is suitable for Grade 1 math practice, independent work, review, or a short assessment, and it includes a complete answer key.

This Grade 1 worksheet practises finding 1 more, 1 less, 10 more, and 10 less for numbers from 5 to 96. Its 13 items combine 9 multiple-choice questions with 4 fill-in-the-blank questions, helping students recognise how adding or subtracting 1 changes a number compared with changing its tens value by 10.
Introduce the worksheet by modelling one example of each change, such as moving from 9 to 10 for 1 more and from 38 to 48 for 10 more. Ask students to explain whether the ones digit or the tens digit changes, then have them complete the multiple-choice items before using the fill-in-the-blank questions to check independent understanding.
Watch for students who add or subtract 10 when an item asks for 1 more or 1 less, or change the ones digit when the task requires changing the tens value by 10. Students may also select a distractor that reverses the direction, such as choosing 66 instead of 54 for 10 less than 64, so ask them to state whether the number should increase or decrease before calculating.
