One-to-one correspondence is a basic math skill in which children pair one object or name with a number. As a benchmark standard for learning during the kindergarten year, young children can develop this type of pairing knowledge through hands-on math activities that encourage matching quantities.

Memory Cards

A memory match activity can teach kindergarten students one-to-one correspondence while also building recall and recognition skills. You can use a ready-made deck of memory cards, or get crafty with your kindergartner and create your own. Write the numbers one through 10 on index card, with one numeral on each card. Make another deck of cards that corresponds to those numbers. Have the child draw shapes or use stickers. For example, draw one star on one card, two on the next, three on the next, and so on for each card. Flip the cards over and spread them out on a desk. Have the child flip over two cards. Ask if the number matches the amount in the picture of the other card. If not, flip them back over and repeat the process. The child needs to remember where she put each card to match them.

Money Match

A money match game teaches kindergarten students to pair like quantities and helps them to build financial literacy. Start with one pile of pennies, nickels, dimes and quarters. Use up to 10 of each. Separate one of each coin out, and line them up. Ask the students to put the other coins in a line behind the one that they match with. For example, the student will put the other nine dimes in a vertical line following the first one that you have set out. You can add to this activity by using numeral cards. Write the numbers one through 10 on index cards. Place the cards face up. Have the students match the number of coins with the number on the card. This means that the students would put one penny on the number one card and so on.

Roll the Dice

Kindergartners can match the numbers that they count with groups of objects in the same quantity. Start with one die. Before the students roll it, gather together a basket of small plastic toy animals, buttons, beads or other similarly sized objects. Ask one child to roll the die. Have him count the dots and tell you the quantity. Next, ask him to count out the same number of items from the basket. He will place these next to the number he rolled. Snap a picture of the pairing. Print it out and have the child write the numeral for the quantity on the photo or on a card that you place below. Repeat for other numbers, making a photo display for the kindergartners to use during a post-activity reflection. Discuss the activity and have the students point out the matching numbers.

Sort and Match Colors

Combine color and number recognition skills into a one-to-one correspondence activity for kindergartners. Give the students a bin or basket filled with different colors of items. You can choose which type of object you want to use. Examples include buttons, beads, crayons or candies. Cut out index card-sized pieces of colored construction paper. Start with one color per one piece of paper. Have the students match the one object to its like-colored piece of paper. Next, have the students group up to 10 items of the same color on the matching piece of paper. Ask the students to count each quantity and write the number onto the paper. You can add a graphing activity by supplying the students with different quantities of colored objects. For example, four green crayons, three red ones, five blue ones and seven purple ones. After the students sort and match the crayons. Chart how many of each the students counted using a bar graph that has the colors written on the bottom and the numbers on the side.
