Printable Dividing by 6 Flash Cards
Dividing by 6 spans 6 ÷ 6 to 72 ÷ 6 — the first deck in the harder half. A number divides evenly by 6 exactly when it is even and its digits add to a multiple of 3, because 6 is 2 × 3.
How to Use These Flash Cards
Think multiplication on every card: 42 ÷ 6 asks 6 × what makes 42. If a card stalls, halve first (since 6 = 2 × 3, half of 42 is 21, then 21 ÷ 3 = 7). Run this deck after the 6 times table deck and keep 42 ÷ 6 and 48 ÷ 6 in the repeat pile until instant.
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
How can you tell if a number divides evenly by 6?
It must pass both smaller tests: even (divisible by 2) and digits summing to a multiple of 3. 54 qualifies — it is even and 5 + 4 = 9 — so 54 ÷ 6 comes out even at 9.
What is the two-step trick for dividing by 6?
Since 6 = 2 × 3, halve the number and then divide by 3: for 66 ÷ 6, halve to 33, then 33 ÷ 3 = 11. Slower than recall, but it never fails.
Which dividing-by-6 facts stall most?
42 ÷ 6 = 7 and 48 ÷ 6 = 8 — the reverses of the hardest 6s multiplication facts. Drilling the pair 6 × 7 = 42 and 42 ÷ 6 = 7 together fixes both directions at once.
