Original Prompt

Create an interactive learning resource that teaches students to develop fluency in two-digit addition by decomposing numbers into tens and ones, then systematically combining like place values. The resource should guide learners through the conceptual understanding of why this strategy works mathematically, provide multiple worked examples with visual representations, and include progressive practice opportunities that build from concrete manipulatives to abstract mental calculations. Students

This resource focuses on teaching students the decomposition strategy for solving two-digit addition problems. The learning objective is for students to develop fluency in solving these problems by breaking numbers into tens and ones, allowing them to combine like place values to ensure accuracy and enhance their mental math skills. It includes worked examples, guided practice, independent practice, and self-check opportunities to reinforce understanding. The document emphasizes the importance of recognizing groups of ten to improve addition speed, and it encourages students to reflect on their confidence and strategies for future improvement.
