One-to-One Correspondence Activities for Preschool, Pre-K, and Kindergarten
What is One-to-One Correspondence
One-to-One correspondence is a foundational math skill for preschoolers. It can take months or even an entire year for preschoolers to master this skill. For this reason it is important to provide your students with plenty of opportunities to practice one-to-one all year long.
Use one-to-one correspondence to solve problems by matching sets and comparing number amounts and in counting objects to 10 and beyond and to recognize the number of objects in small groups without counting and by counting (NCTM)
One to One Rubber Duck Counting
This activity is so much fun for kids! They could play this game for hours and hours and it’s great for 1:1 practice too. First, start by reading a book about ducks to your kids. 10 Little Rubber Ducks by Eric Carle or Five Little Ducks by Pamela Paparone are both perfect for young children. Place a shallow bowl of water in the middle of the table. Give the kids one foam dice and have them take turns rolling it. Children will count the dots on the dice and place the corresponding number of mini rubber ducks in the “pond”. If counting to six is too hard for your kids, tape a piece of paper over the higher numbers and put one or two dots on the paper instead.
Spill the Bears
Place a certain number of teddy bears in the plastic cup and put the lid on. Have students sit around a table or in a circle on the floor and take turns shaking the cup and “spilling” the bears out. Students count the bears each time they are spilled using their fingers to touch each one. This game sounds very simple but you would be surprised how many children don’t know how many bears there are in the cup until they count them, even though it’s the same amount each time and several kids had a turn before them. We play Spill the Bears once each month with a different number of bears. In September we used only two bears to play the game, in October we used 3 bears, and in November we used 4 bears etc. If you use Teddy Grahams instead of plastic bears the students may eat the bears after counting them correctly.
Ice Cube Tray Games
The erasers pictured here are flowers to go with our spring theme. To play this game each child gets an ice cube tray. Students sit around a table and take turns rolling the dice. Students must place the correct number of erasers in the ice cube tray that correspond with the dots on the die. The object of the game is to fill your tray with erasers.
You can use metal, plastic, or cardboard muffin containers, whatever you prefer or can find easily. I found cardboard muffin containers at my local grocery store that work great for this activity. Write a number in the bottom of each muffin space with a permanent marker. Next, provide a large variety of different buttons for the students to count and place in the correct muffin spaces. For example, four buttons would go in the space with number four written in the bottom.
