Number Game with Random Digits

Resource Info

Basic Information

Swati shares a game from Swanirvar/Shikshamitra that assesses number operations and demands higher order thinking skills. Did we tell you that it is a cheating proof game!?

About the game

  • This game can be used to practice addition, subtraction, multiplication and also division
  • This game facilitates higher order thinking in math
  • It needs at least 2 players – the more the merrier!!

In each case the goal should be to get either the maximum number or the minimum

(Note to the instructor)

1. Grid possibilities

  • Keep the total number of boxes at most 9 in any grid
  • Ideally have 6-8 boxes in a grid
  • Addition grids can have 2-4 rows of same or varying lengths
  • Subtraction and multiplication grids can have 2 rows with 2-4 digits each
  • In subtraction, a player might encounter negative answer – if that happens before introduction to integer, the player has to abstain from playing that round
  • For division, the dividend can be 4-7 digits and the divisor 1-2 digits

2. Why not repeat?

  • Using repeated digits may make the game too random to strategize
  • The ulterior motive is to develop higher order thinking while strategizing
  • If it is too random, this purpose gets defeated
Activity Steps: 

How to play

  • Each player makes or gets the grid chosen by the facilitator
  • (Sample grids are included in last two slides)
  • Facilitator announces the goal i.e. maximum or minimum
  • Facilitator dictates a digit (from 0, 1, 2, 3 … 9)
  • Each player must immediately write it in one of the boxes
  • Once written, it can not be changed
  • Zero can not be written as a leading digit
  • Facilitator dictates more digits without repetition and players keep writing till the grid is filled
  • Once the grid is filled each player computes his/her corresponding answer
  • Note that since the digits are randomized, copying/cheating from others does not help!!
  • Cross check answers and then compare them to find the winner
  • It is a good idea to compute the maximum/minimum that would have been possible with the given digits
  • It is possible that no player actually got the theoretical maximum/minimum
