This file contains the notes I took at the NCTM Conference in Chicago. I attended a presentation on Subtraction by Frances Stern. She taught various ways to subtract with regrouping. My most favorite to use in class is the number line and France's way on pages 6-7. The France way is what I refer to in my class as "Give, Give It Back"...It's SO MUCH EASIER TO TEACH AND UNDERSTAND than the Traditional U.S. way. I don't know where this has been all my life. Please give it a try! It takes some pract

Regrouping Template for 2 - 3 - 4 Digit Addition or Subtraction

Created by

Honey Pie

Mastering the standard algorithm for multi-digit addition and subtraction is an essential part of elementary math education. These regrouping templates are specifically designed to support students as they learn and practice adding and subtracting 2-digit, 3-digit, and 4-digit numbers using clear, structured layouts. Each template serves as an anchor chart that visually breaks down the process of addition or subtraction. With dedicated columns for ones, tens, hundreds, and thousands, students ca

Additive Strategies – Sequence of Learning (NSW Curriculum)

Created by

NquirED

This resource is a clear, structured reference guide for teachers outlining the developmental progression of additive strategies from Early Stage 1 to Stage 3, aligned to the NSW Mathematics curriculum. Rather than isolated strategies or lesson ideas, this document maps how additive thinking develops over time, showing the conceptual links between counting, part–whole understanding, equality, mental strategies, written algorithms, and problem solving. It is designed to support professional learn
