The product game in ESO First Grade

Working with the unit about divisibility, in ESO 1st Grade, we found an interesting game to play in class. It is called the product game, and it looks something like this:

The Object of the Game is to get four squares in a row—vertically, horizontally, or diagonally.

  1. To begin the game, Player 1 moves a marker to a number in the factor list of numbers 1-9 along the bottom of the game screen.
  2. Player 2 then moves the other marker to any number in the factor list (including the number marked by Player 1). The product of the two marked numbers is determined, and that product is colored red for Player 2.
  3. Player 1 moves either marker to another number, and the new product is colored blue for Player 1.
  4. Players take turns moving a marker, and each product is marked red or blue, depending on which player made the product. However, if a product is already colored, the player does not get a square for that turn.
  5. Play continues until one player wins, or until all squares have been colored.

We were playing in both classes of ESO 1st Grade, and we divided the classes into four teams. So we could play two semifinals, the match for the third and fourth position, and the final game. Here are the teams of 1-A, ordered from first place to last place:

  • Here you have the winning team, a team including Ángel Mendoza, Daniel Gago, Luis Pérez and Alberto Ramírez
