The Big Thinking Behind Two Digit Adding

How do numbers hide in everyday life? This animation explores two-digit addition using real-world examples from food pantries, parks, offices, and fundraisers. Learn to add two-digit numbers, spot patterns, use friendly numbers, and check your answers with confidence. Watch the video to discover how the same math problem can be solved in multiple ways, and why that makes you a stronger mathematician! Test your thinking with the pause-and-predict questions built right into the video. Two-digit addition is more than just getting the right answer. It's about flexible thinking, smart strategies, and noticing patterns that make math faster and easier. So, get ready to add, adjust, and think like a mathematician! Use this video in your classroom to introduce two-digit addition strategies. Or use it as part of a digital lesson plan. The content within the video is designed for students in grades 2 and up.

Where to Use this Video with the New Georgia Learning Plans 2nd Grade – Unit 2, after the 5th lesson What is this? Hi there! This video and others like it are designed to include real-world, complex problems that require thinking and multiple steps to solve. Today, a shift is occurring in mathematics classrooms across the US to encourage problem-solving. I create videos to help teachers increase complex problem-solving opportunities in their classrooms and help students become better problem solvers. The mathematics targets middle-grades through traditional Algebra I students. Come explore a world of mathematics with me. Please subscribe to my channel for more videos involving mathematics and multistep problem-solving situations. Consider sharing this video or my channel with your math teacher friends and family!
