Printable Subtracting 6 Flash Cards
Subtracting 6 is best handled with think-addition: 14 − 6 answers fastest as "6 + what makes 14?" These fold-over flashcards cover 7 − 6 through 18 − 6, the reverses of the +6 deck card for card.
How to Use These Flash Cards
Flip every stall into addition — 13 − 6 asks 6 + what makes 13, and the +6 deck already covered 6 + 7. The bridge works too: 13 − 3 is 10, then 3 more back is 7. Keep 12 − 6 = 6 (the half fact) instant and let 13 − 6 and 14 − 6 live in the repeat pile a while.
How to Cut and Fold
- Print the PDF single-sided on plain paper or light cardstock.
- Cut along the solid lines to separate the cards.
- Fold each card along the dashed center line so the answer sits behind the question, and turn the card over like a page to check.
- Optional: a dab of glue inside the fold makes a sturdy double-thick card.
Frequently Asked Questions
What is think-addition for subtraction facts?
Reading 14 − 6 as "6 + what makes 14?" — riding the addition facts backward instead of counting down. It is the subtraction twin of the division decks' think-multiplication, and it scales where counting back fails.
Which −6 facts stall most?
13 − 6 = 7 and 14 − 6 = 8, mirroring the hardest +6 facts. Drill each with its addition twin (6 + 7 = 13, 6 + 8 = 14) so both directions strengthen together.
How does bridging ten work for 15 − 6?
Split the 6: take 5 to reach 10, then 1 more lands on 9. Bridging and think-addition give every card two roads — children should own at least one and ideally both.
