Missing Addend Subtraction Slides, 1st Grade Math Centers

Missing addend subtraction slides give first graders the focused, independent practice they need to master one of the trickiest early math skills: finding the unknown number in a subtraction equation. Designed for Common Core Standard 1.OA.D.8, this digital resource covers subtraction within 12 across 51 problems, all delivered in a press-and-play format that runs itself from start to finish.

No setup, no printing, no laminating. Open the PowerPoint or movie file, press play, and the slideshow takes over. Problems appear on screen, students respond on a whiteboard or work mat, and the correct answer reveals itself automatically before moving to the next question. Students who finish early can jump in mid-slideshow without missing a beat, making this a natural fit for first grade math centers, early finisher time, or small group intervention.

WHAT'S INCLUDED:

• PowerPoint file with 51 missing addend subtraction problems
• Movie file version of the same slideshow, easy to speed up or slow down
• QR code cards so students can access the activity independently
• Printable work mat, compatible with dry-erase boards

HOW THIS WORKS:

• Open the PPT or movie file and press present or play
• Students write their answer, then the correct answer appears on screen
• The slideshow advances automatically, no clicking required
• Early finishers can join at any point during the rotation

PERFECT FOR:

• First grade math centers and independent work stations
• Early finisher activities during whole group instruction
• Math intervention and skill reinforcement for 1.OA.D.8
