Inside: What is one-to-one correspondence counting and activities to help your child develop this important numeracy skill.
The journey of parenthood is filled with numerous milestones, and one of the most exciting moments is when you hear your child proudly recite the numbers "1, 2, 3" for the first time. Witnessing their growing understanding of numbers is a source of immense pride, as children quickly add more numbers to their list and astound us by counting quickly to higher numbers, surpassing our expectations.
However, here is an important question that warrants more attention: “Is my child truly counting correctly?” Being able to recite the names of numbers in their correct order is an essential skill but it’s important to recognize that this alone doesn’t confirm a child’s ability to count accurately.
True counting proficiency goes beyond mere recitation of numbers. It hinges on a concept known as "one-to-one correspondence," an essential skill that forms the basic numeracy foundation.

What is one-to-one correspondence counting?
One-to-one correspondence counting is a way of counting where each object you are counting corresponds directly to one number. This means that when you count, you are saying one number for each object, and you do not skip any objects or say the same number for multiple objects.
How do you tell if your child understands one-to-one correspondence counting?
Imagine your child counting some apples. If your child is able to point at each apple and say a number "One" for the first apple, "Two" for the second, "Three" for the third, and so on, your child is demonstrating one-to-one correspondence counting.
Each apple gets its own number, and your child doesn't miss any or repeat any numbers. Your child’s counting matches the actual number of apples there are.
Why is one-to-one correspondence important?
One-to-one correspondence is an important numeracy skill to learn because it helps children count things accurately and understand the relationship between numbers and the things they represent.
In 1978, psychologists Dr. Rochel Gelman and Dr. Randy Gallistel introduced one to one correspondence as one of the five counting principles that would help ensure proper counting.
Hence as parents or educators, we must delve deeper into their understanding of counting and give them ample opportunities to explore, learn and showcase their grasp of one to one correspondence counting.
In the following section, I will be sharing with you five engaging and simple activities designed to help your child develop one to one correspondence counting.
10 Fun Activities to Help Your Child Learn One-to-One Correspondence
Activity 1: Sock it to ‘em
This first setup is very simple and only requires socks. Separate the pairs and sort them into two piles. Take one pile and line them up neatly and give the other pile to your child. The goal is to match up the socks (one at a time) from their pile to the ones in the line until all socks have been paired up. As your child completes each match, have them count it out loud to you.
Activity 2: Line up the liners
Write the numbers 1-12 on cupcake liners and have your child place one liner at a time in numerical order in a cupcake tin. You can create a simple handwritten number line for your child to look at if they need help putting the numbers in order.
Activity 3: Eggscellent counting
Write the numbers 1-12 in an egg carton and on 12 plastic eggs with a dry erase marker. Have your child match the number on the egg to the number in the carton to practice one-to-one correspondence.
Activity 4: Turn by Turn
Place 10 blocks in a straight line and write the numbers 1-10 on index cards. Line up the cards next to the blocks and place them in numerical order but face down. Have your child turn over the card next to each block and say the corresponding number out loud.
Activity 5: Paint Stick Counting
Grab a paint stick from your local hardware store, 10 different colored markers, and 10 clothespins. Draw different colored dots on the paint stick. Write 1-10 on the clothespins and mark them with different colored dots too. Have your child match the colored dot on the clothespin to the same dot on the stick and clip it on in numerical order.
Activity 6: Pouch Cap Flower Counting Caps
A hands-on learning toy for children to practice one to one correspondence counting using pouch caps.
Activity 7: Paper Clip Counting Flower
Add paper clips to create a flower and practise counting.
Activity 8: Counting Heart Printable
Download this free printable and explore these hands-on activities for your child to practise one-to-one correspondence counting from 1 to 5.
Activity 9: Bottle Caps Ice Cream Counting Board
Keep those bottle caps and make this fun ice cream counting board. Children scoop pompoms into the bottle caps and learn counting at the same time.
Activity 10: 10 Frame Flip Board
A hands-on learning toy to give your child lots of practise with counting from 1 to 10.

Commonly asked questions about one-to-one correspondence counting
One-to-one correspondence means matching each thing you're counting with one and only one number, so you don't skip or repeat any. One-to-one correspondence is an important numeracy skill to learn because it helps children count things accurately and understand the relationship between numbers and the things they represent.
Counting and one-to-one correspondence are related but not exactly the same. Counting involves saying numbers in order (like "1, 2, 3..."), while one-to-one correspondence goes a step further. It's about matching each number you say with a specific object you are counting, making sure you give each object a unique number and not skipping or repeating any. Counting is part of one-to-one correspondence.
Teaching counting with one-to-one correspondence involves helping children understand that each object gets its own number, and those numbers are said in order without skipping or repeating. The best way for young children to learn one-to-one correspondence is through hands-on activities where they get to touch or move an item and count at the same time.
Rote counting is reciting numbers in order (like 1, 2, 3), often memorized. One-to-one correspondence means matching each object with a number when counting, ensuring accuracy.
Children typically start to develop one-to-one correspondence skills around the ages of 3 to 4 years old. During this time, they begin to understand the concept that each object corresponds to a specific number when counting. Initially, they might use their fingers or other physical cues to help them keep track of objects and numbers. Remember that every child develops at their own pace, so the exact timing can vary.
