With Jane and Joanne
Grades 4 and up
4 players (2 teams of 2) or 2 players (1 vs. 1)
- playing cards Ace (=1) through 9
- paper and pencil
Players turn over four cards from the top of the deck. These cards are added to each other to result in a sum. Each team lists as many possible factors of this sum.
Players draw the cards 6, 8, 6, and 4. When added together, these numbers result in a sum of 24 (6 + 8 + 6 + 4 = 24).
- Team 1 lists the factors of 24 as 1, 2, 4, 6, 12, and 24.
- Team 2 lists the factors of 24 as 1, 2, 3, 4, 6, 8, 12, 24.
Teams compare their answers and give the opposing team 1 point for each correct factor. In the case above, Team 1 earned a point for each of its six factors (6 points) and Team 2 earned a point for each of its eight factors (8 points). After the first round, Team 2 is in the lead by 2 points.
If one team lists a factor incorrectly, they lose 1 point from their total.
Play continues until one team earns a total of 100 points.
