Trading Tens: Subtraction with Regrouping (Borrowing) – Hands-On Lesson
Help students finally get subtraction with regrouping by trading tens, not magic borrowing. This complete lesson walks learners from concrete base-ten models to written algorithms, locking in the idea that when you regroup you add 10 to the place that needs more because you take 1 ten from the next place. Perfect for whole-group instruction, small groups, interventions, or sub plans. What’s Included Teacher Notes with objective, key insight, and step-by-step flow Anchor Chart: “What Really

CGI- Strategy Practice for Addition
After teaching 2nd grade for several years, I observed that my students were confusing the following strategies: direct modeling, counting on, counting back, and using invented algorithms. Therefore, I created this resource to model the different strategies for students. This product is practicing addition from 1 + 2 up to 1+ 10 for the number sets 1-10.There are 90 different problems categorized in numerical order. This product can be used for direct instruction, practice, and/or assessment.
