ThinkabaraWhy “every answer is 6, 7 or 67” works
Teachers everywhere hear “six seven!” whenever those numbers show up. Instead of fighting it, this challenge makes the numbers the goal. Knowing the answer set does not give the answer away — students still have to add, divide or solve for x — but it gives them a built-in check. A child who gets 76 on a subtraction problem immediately knows to look for a regrouping mistake. That habit of checking whether an answer makes sense is one of the most valuable things a math class can teach.
What each grade practices
| Grade | Problems |
|---|---|
| 1st | Addition and subtraction within 20, missing addends, counting dots, 6 tens and 7 ones, adding 10. |
| 2nd | Two-digit addition and subtraction to 67, 10 more / 10 less, place value, cents word problems. |
| 3rd | Multiplication and division facts with 6 and 7, three-digit subtraction, rounding, equal-sharing word problems. |
| 4th | Dividing by one- and two-digit numbers (268 ÷ 4 = 67), missing factors, tens in 670, money word problems. |
| 5th | Decimals and powers of ten (6.7 × 10, 0.67 × 100), order of operations (8 × 8 + 3), hundredths place. |
| 6th | One- and two-step equations (3x − 5 = 16), exponents and square roots, greatest common factor, ratios and percents. |
Choose any mix of facts, place value and word problems, and 10, 16 or 20 problems per sheet. Every sheet is new; press New sheet for another.
Classroom ideas
- 67th day of school. Many classes celebrate the 67th day: do the worksheet as morning work and end the day with a class game.
- Call and response. Teacher reads a problem, the class answers together — “six!”, “seven!”, “sixty-seven!” The phrase becomes participation instead of interruption.
- Imposter hunt. Turn on imposters and make finding them the goal. Partners compare which problems they circled and prove their answers.
- Write your own. The bottom of every sheet asks students to write a problem whose answer is 67. Collect them for tomorrow’s warm-up.
- Brain break. Put the 60-second sprint on the board; kids stand up for 6, touch their toes for 7 and jump for 67.
Playing the online sprint
Pick a grade and press Start. A problem appears with three big buttons — 6, 7 and 67. Answer as many as you can in 60 seconds; a wrong answer shows the right one before the next problem. Turn on imposter mode for a fourth “Neither!” button. Your best score is saved on this device only — no accounts, no names, nothing uploaded. On a keyboard, press 6, 7 or 3 (for 67).
Tips for parents
If your child is already saying “six seven” at dinner, a sheet like this is an easy way to sneak in practice. Do a few problems together, then let them make up one for you. Keep it light: the joke is the hook, the math is the point.
Frequently asked questions
What is a 6 7 math worksheet?
It turns the “six seven” phrase kids love shouting into real practice: every answer on the sheet is 6, 7 or 67. Students still have to solve each problem, but they also get an instant self-check — if the answer is not 6, 7 or 67, something went wrong.
Which grades is it for?
Grades 1 to 6. First grade gets addition and subtraction within 20, counting and tens-and-ones. Higher grades add multiplication and division facts, multi-digit operations, decimals, order of operations, simple equations and word problems — all landing on 6, 7 or 67.
What are the imposter problems?
An optional twist: two or three problems have an answer that is close but different (like 66 or 8). Kids must solve them anyway and circle them. It stops guessing and rewards careful checking. Turn imposters off for a straightforward sheet.
Is there an answer key?
Yes. Tick “Answer key page” and the key prints right after the worksheet, with imposters marked. Each sheet also has a code, so you can print the same sheet again later.
How do I use it for the 67th day of school?
Print a sheet for morning work, play the 60-second game as a class on the board (students call out 6, 7 or 67), and finish with the “write your own problem whose answer is 67” challenge at the bottom of the sheet.
