Teaching the Standard Algorithm!
This powerpoint is interactive and color coded. It helps teach the standard algorithm, with not just digits but an understanding that that digit in a specific place value has a worth/value. Example: the digit 7 in the tens place is worth 70. I want the students to have an understanding when they add and a true number sense, and not just go through the motions. There are place value charts, pictures, place value discs, and color coding to help the students understand how to add two and three digi

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

2-digit Subtraction on a Number Line PPT Lesson
Using a number line to subtract is a great way to support second graders in using place value strategies rather than jumping directly into the standard algorithm. This powerpoint presentation models how to count back to subtract on a number line. It also shows how to count between to subtract. These two strategies build a strong number sense and understanding of the process of 2-digit subtraction. By the end of the lesson (which can be split over 2-3 days based on student needs), students will b

Your students will think it’s a game; a chance to “take on the teacher.” You know that by playing this game, your students will review and practice borrowing and carrying skills and practice the steps of the addition and subtraction algorithms.
“Build a House”™ is a fun, fast-paced math game with the same rules as “Hangman,” but instead of your students calling out letters, they call out numbers. Instead of hanging a poor, unfortunate stickperson, incorrect guesses will build you a house.
