Interactive Addition & Subtraction Lesson

I’m pulling together a fresh math block for my 9–10-year-olds and want the entire session built around hands-on, interactive activities. The focus is strictly on two areas—basic addition & subtraction and word problems—so every game, station, or challenge you design should reinforce one or both of these skills without drifting into other strands of the curriculum.

Please structure the content so it can fill roughly 45-60 minutes, flows naturally from a quick warm-up into collaborative tasks, and ends with a short reflection or exit ticket. Feel free to leverage familiar tools such as Google Slides, Jamboard, or printable task cards; just make sure the resources are easy for me to edit later and require minimal classroom prep.

Deliverables I need from you:
• A step-by-step lesson plan outlining timing, objectives, materials, and facilitation tips
• Ready-to-use activity materials (slides, printable worksheets, or digital links)
• Separate answer key for every task and clear solutions for the word problems
• Brief teacher notes suggesting differentiation ideas and common misconceptions to watch for

I’ll review the lesson by teaching it once and will sign off when all materials work smoothly with my students, the tasks stay interactive throughout, and the objectives are met within the allotted time.
