Boost your students' subtraction fact fluency with these engaging and interactive flashcards!

Self-Checking Design: Each card comes with a hidden answer, revealed only when viewed through a red magnifying glass. Students can easily check their work using any transparent red material, such as a commercially available red reader or a DIY red cellophane sheet.

Easy to Use: Print, laminate, and go! Students can write their answers directly on the laminated cards and wipe them clean to practice again and again.

Bonus: Includes blank flashcards!

Printing Tips: To ensure the best results, test your printer with a single page to confirm ink or toner levels before printing the full set. The included PDF offers two versions with different ink intensities—choose the one that works best with your printer.

These flashcards make mastering addition fun and efficient!
