Original Prompt

can you make a page of subtraction with and without regrouping where they need to identify if they have to regroup or not?

This learning resource is focused on mastering 2-digit subtraction, specifically targeting the concept of regrouping. Students will learn when to apply regrouping by assessing the ones place of subtraction problems. The document outlines a clear regrouping check rule, explaining that if the digit being subtracted is larger than the starting digit in the ones place, regrouping is necessary. An illustrative worked example (52 - 27) is provided to clarify the process. Following the introduction, students will engage in independent practice by solving 15 subtraction problems while determining if each requires regrouping. The resource concludes with a self-check reflection prompt to encourage students to identify areas for improvement in their subtraction skills.
