I learned **Pass and Fold** from Jen Sauriol at a Landmark School Outreach PD this summer. This game works best to help students practice or memorize facts that convert back and forth. It could also be used as a repetitive arithmetic game.

*Examples of topics to use this game*:

- Converting between fractions, decimals, percents
- Switching between roots and squares
- Complementary or Supplementary angle pairs
- Continuously adding -2 or multiplying by -2 (or any other number)
- Slope of a parallel line
- Practicing state capitals
- Conjugating verbs in foreign language class

Once you have selected a topic, you will need about 9 basic questions to start. For my example, I will choose finding the supplementary angle. Click here for file.

First divide your paper into thirds vertically. At the top of each column write an angle measure, so let’s just choose to could by 10s, so 10, 20, 30 … until I get to 90-degrees. For the first few times you play this game, you should also make horizontal lines to indicate where to put their answers.

Then make copies, so you’ll have enough for each student to have 1/3 of a sheet to start. Cut them into thirds and you’re ready to go. **Easy prep! **

**How to play**: (*Teacher tip*…practice passing the papers without any writing until you see they can do this without thinking. It might take 5, 6 or even 10 times.)

- Look at the angle measure at the top of your sheet.
- On the next line, write the supplementary angle.
- Then fold the original angle to the back of your paper, so only your answer can be seen.
- Pass the paper according to the pattern you practiced.
- The next person, writes the supplementary angle, and folds back the angle above.

After you have passed the papers about 10 times, stop and have the students unfold their paper. It should reveal a repeating pattern.

For instance:

Original Angle: 30-degrees

150-degrees

30-degrees

150-degrees

And so on down the page

If there are any that do not repeat, such as my jokers who started with 50, but wrote 69, so the next answer was 111, then 69, then 111, you can talk about why there was an error. I called this a judgement error. Sometimes there are math errors or misunderstandings to correct.

Most importantly, it takes a boring repetitive task and turns it into a fun fast based group activity.
