Use this interactive worksheet to practice mentally finding the number that is 1 more or 1 less than a given number up to 100.

Students roll a number cube and solve a problem based on their number. Then, they find the answer and color it in. This resource would be great to use as a math center activity or as independent practice after a lesson.

How to Differentiate This Resource for Your Students:

• For students struggling with this skill, provide a hundreds chart and a counter for them to use. Students will place the counter on their starting number and add or subtract 1. This will allow them to see the patterns in our number system.
• For students who need a challenge, why not make it a competition? Partner up two students and have them take turns rolling and coloring. The first student to complete their chart wins!
• Another way to challenge your students is by letting them complete the 10 more, 10 less version! Click on the link below to download a copy.

Use the drop-down menu to choose between the PDF or Google Slides version. An answer key is included in the download.
