Guess the Number Yes/No Game Maths Cut-Out Cards (Number Grid 1-15 STEM)

Introduction: Guess the Number Yes/No Game Maths Cut-Out Cards (Number Grid 1-15 STEM)

About: I’m a technologist and love to write about all things digital on my blog TheDigitalBrief.com but I also have a love of all things analogue and making stuff from scratch! I also build RaspberryPi projects... ...

This is fun project for kids and Maths Teachers to make with their students. I actually learned this when I was 10 years old at school but I’ve sadly never seen it shared online so of course I set about rectifying this oversight and here it is in all its glory! The game allows you to guess anyone’s number between 1 and 15 through process of elimination using cards with a 4x4 grid.

The best part is the number is presented via a 'cut out' window on the reverse!

  • All you have to do is ask the ‘soon to be amazed’ contestant to choose a number between 1 and 15.
  • Ask them if they can see the number on card 1.
  • If they say ‘yes’ place the card at the back with ‘yes’ at the top. If they say ‘no’ turn the card so ‘no’ is at the top and place at the back.
  • Do the same for cards 2 and 3.
  • Ask the same question for card 4 and turn it so ‘yes’ or ‘no’ is at the top but do not move it to the back!
  • Turn the cards over and on the rear will be the number they chose!

Supplies:

  1. White card 160gsm (or greater if your printer allows)
  2. Colour Printer
  3. Scissors
  4. Glue Stick
  5. Ability to count to 15 and be a performer!
