Your students will enjoy solving a bunch of valentine-themed number mysteries with this cute game. Dragon Mystery Number will have your students practicing number recognition from 10 - 23 as well as greater than (more) and fewer than (less) concepts. This will allow students to practice the Common Core standard 1.NBT.3 : Compare two two-digit numbers based on meanings of the tens and ones digits, recording the results of the comparison with the symbols for greater than, less than, and equals.
You will need to create a number line by printing and gluing the provided number line pieces together. You can print them on cardstock and laminate or print on copy paper and glue on to a sentence strip prior to laminating to make it more durable. Cut out the lollipop and cupcake dragon cards and numbered sweetheart dragon cards. Laminate these as well. As an extension, there are two recording sheets (more or less) to copy for student use. Students can pick two numbered sweetheart dragon cards and write an equation using the numbers and correct signs.
Students should place the greater than (lollipop) and less than (cupcake) dragon cards at each end of the number line to start the round. Player A draws a sweetheart dragon number card from a bag or container (I use an empty boutique tissue box.). This is the mystery number for this round. Player B makes a guess for which number Player A drew. Player A tells Player B if the number is too high and slides the lollipop dragon from the right to that number or if it is too low and slides the cupcake dragon from the left to that number. (Example: If the mystery number is 9 and Player B guesses 3, Player A will slide the cupcake dragon to that number. If the guess is 10, player A will slide the lollipop dragon to that number.) Player B keeps guessing and Player A keeps moving the lollipop and cupcake dragons until Player B can solve the mystery. The sweetheart dragon card should go back into the bag or container. Now the players switch and Player B shakes up the bag or container and picks the new mystery number and Player A gets to make guesses. To add a degree of difficulty for your more advanced students, have each student draw two cards out of the bag or container and write either greater than or less than equations on either of the included recording sheets.
