More About Larger Numbers

Something we need to practice in kindergarten is to use ten as a base for adding other numbers onto. One of the things we are practicing with our numbers 11 through 20 is if we have ten how many ones are left over to make a particular number. For example, 17 is ten plus how many more? Seven more are needed to make 17.

A game you can play to practice this is to use playing cards. Take out all the face cards as they won't be needed in this game. The Ace counts as one. Put one of the tens on the table right side up. Shuffle the remaining cards and deal out the rest of the cards to the players. The first player draws a card and figures out how many ten plus his/her number equals. S/he tells the number out loud. The next player takes a card and puts it by the ten and figures out how much his/her number equals with the ten and says the answer. The person who has the largest number gets to keep the two cards that were drawn. (The ten stays on the table.) If the player needs to count the shapes or count on to figure the answer, that is fine but hopefully after awhile s/he will be able to say the answer automatically. Play until one player has all the cards or someone wants to quit. The person with the most cards wins.
