Practice crossing over to the next decade with this Concentration FREEBIE!
Materials: Please copy the end of the decade cards (9,19,29,39, 49, 59, etc) back to back with the logo on color cardstock. Next, run the decuple numbers (10, 20, 30, 40, 50, etc.) back to back with the logo on a different color cardstock. You will need to discard any blank cards. ***Due to copiers being different, you may need to flip the papers in different arrangements to get them to match up when running back to back. Another option is to just print the numerals without the logo on the back. ;-)
Directions: Players take turns drawing a card from the left (mine are blue) and then they draw a card from the right (mine are purple) to see if they have a match with the end of the decade and the next decuple. For example, if they draw a 49 from the left, they will be looking for a 50 on the right.
Play just as you would the traditional game of Concentration. If you get a match, keep the match by you. Players take turns looking for matches and the player with the most matches at the end is the winner!
Backward Sequencing Option: If working on sequencing numbers backward, you could always have them draw from the purple side first….and then think about what decade they would move into if going backward. For example, if they drew an 80 from the right, they would be looking for 79 on the left.
