- Players take turns pulling two cards from the deck and arranging them to make a number.
- Jacks will represent the number zero.
- Players choose which number will represent the tens place and which number will represent the ones place (e.g., If they pull a three and six, they can create 36 or 63, depending on their strategy).
- The player places a chip on the corresponding number on the 100 frame.
- Place the used cards in the discard pile and the next player takes their turn.
- If a player pulls a number that has already been covered, the player will miss their turn (e.g., If 36 and 63 are already taken and they’ve pulled a 6 and 3, they miss a turn).
- Optional: If a player pulls a number that has already been covered, they can remove the players chip from the 100 frame and cover it with their own chip.
- If a player pulls two Jack cards, they place a chip on 100.
- The object of the game is to be the first player to place a chip on every row or every column of the 100 frame.
- If players run out of cards in the deck before the game ends, shuffle the discard pile and replay the cards. Game play continues.

- Do younger students comprehend the magnitude of the numbers indicated on the cards?
- What strategies do the students implement to arrange their numbers (e.g., do students intentionally arrange the two numbers to place a chip in a row or column that has not been filled by other chips yet)?
