Skype Mystery Number

On Friday, we used Skype to play a game of "Guess My Number" with the first graders in Miss Klipfel's class.  Using a 120 chart, both classes chose a mystery number for the other class to guess.  Students were invited to the computer to ask questions about the mystery number using mathematical language such as "Is the number greater or less than___", "Is the number between_____ and _____", and "Is it even or odd?" As we gathered more information about the number, we crossed off numbers on our 120 charts (try this game at home)! You can also visit http://www.kidsmathgamesonline.com/counting.html for math games to play on your computer at home. 

Miss Klipfel's class was able to guess our mystery number (106) after asking some great mathematical questions. Nice work, Miss Klipfel's class!  We are looking forward to our next classroom connection using Skype! Common Core Standard: 1.NBT.A.1: Count to 120, starting at any number less than 120.
