Description
Simplify integer addition for your students with this ready-to-use Building Thinking Classrooms (BTC) lesson plan focused on Understanding the Adding Algorithm!
Designed using the principles from Building Thinking Classrooms by Peter Liljedahl, this resource provides everything you need to help students uncover the logic behind the adding algorithm rather than memorizing rules. Through engaging, scaffolded activities, students will develop a conceptual understanding of how and why the algorithm works.
What’s Included:
✅ Complete Lesson Plan – Includes the essential BTC components: Launch, Thin-Slicing Problems, Consolidation Discussions, Guided Notes, and a Check for Understanding.
✅ Thin-Slicing Problems with Task Cards – Problems are scaffolded for incremental understanding, and printable task cards are available for flexible, hands-on practice.
✅ Google Slides Presentation – Pre-organized slides are ready to project and teach, aligned perfectly with the lesson structure.
✅ Student-Friendly Notes – Guided notes help solidify key concepts for future reference.
✅ Assessment-Ready Check for Understanding – Easily track your students' comprehension with the included tasks.
Why You’ll Love This Resource:
Aligned with BTC Practices – Uses proven strategies from Building Thinking Classrooms to foster deeper understanding.
⏱️ No Prep Required – Just download, print, and project. Everything is ready for immediate use.
Engaging & Collaborative – Encourages teamwork and productive struggle through vertical, non-permanent surfaces and carefully sequenced problems.
This lesson is perfect for 7th-grade math teachers looking to implement or enhance their BTC practices while helping students build a conceptual foundation for understanding and applying the integer addition algorithm.
