What Are Numbers?

Numbers are symbols that show how many things are in a group. Learning numbers helps children describe the world around them. For young learners, it starts with seeing, saying, and understanding numbers from 0 to 20.

Examples of Numbers:
  • 0 - Zero: no apples in the basket
  • 7 - Seven: seven pencils
  • 13 - Thirteen: thirteen toy animals
  • 20 - Twenty: twenty stickers
Note

Introduce numbers with real objects that children can see and touch. This builds a foundation for recognizing and understanding number symbols.

Recognizing Number Symbols

Recognizing numbers means knowing what the symbols 0 through 20 look like. This is the first step before counting objects. Children need plenty of practice seeing and naming these numbers.

Try This:
  • Point to a card with the number 4 and say, “This is four.”
  • Find the number 9 in a number chart.
  • Show a group of 16 and match it to the number 16 card.
Note

Use flashcards, charts, or number books to support number symbol recognition. Repeat often and celebrate correct identifications.

Counting Objects from 0 to 20

Counting is saying numbers in order while touching or pointing to each object. This helps children understand that each object gets one count — called one-to-one correspondence.

Practice Counting:
  • Count aloud while lining up 8 blocks: “1, 2, 3, 4, 5, 6, 7, 8.”
  • Place 12 crayons on a table and count them together.
  • Show an empty basket and explain, “Zero means none are inside.”
Note

Encourage children to touch each item as they count. This physical action supports accurate counting and builds attention to detail.

Connecting Numbers to Quantities

Understanding quantity means knowing that the number symbol (like 5) matches a real amount of objects (like 5 toy cars). This builds a strong foundation for future math skills like addition and subtraction.

Hands-On Matching:
  • Match a card with 3 to a group of 3 bears.
  • Show 10 spoons and find the number 10 card.
  • Hold up 0 fingers and say, “Zero means none.”
Note

Use everyday items like buttons, crayons, or blocks for number-quantity matching. This makes learning personal and concrete.

Counting Strategies for Young Learners

As numbers get larger, children need strategies to count accurately. Grouping objects or using visual patterns makes counting easier and builds early math thinking.

Helpful Counting Strategies:
  • Group 10 marbles into two rows of 5.
  • Count 15 stickers by making three groups of 5.
  • Use fingers and toes to represent numbers up to 20.
Note

Grouping objects in 5s or 10s makes counting faster and prepares children for understanding place value in later grades.

Using Numbers in Everyday Life

Everyday activities provide natural opportunities to practice numbers. Counting during play or daily routines helps children see that numbers are part of the world around them.

Everyday Number Practice:
  • “You have 6 crayons in your box.”
  • “Let’s count 14 leaves in the park.”
  • “How many toy cars do you see? Let’s count them.”
Note

Involve children in counting snacks, toys, or steps. This real-world practice makes numbers meaningful and fun.

Interactive Counting Activities

Hands-on activities deepen learning by allowing children to move, touch, and count objects. Interactive play helps children stay engaged and remember numbers better.

Activity Ideas:
  • Build a tower of 9 blocks and count each block.
  • Draw 18 circles and color them as you count aloud.
  • Match number cards to groups of toy animals.
Note

Allow repeated practice with various objects. Repetition and variety help build strong number recognition and counting skills.

Guidance for Parents and Educators

  • Use real objects to make numbers meaningful.
  • Count aloud slowly while pointing to each item.
  • Encourage children to physically touch each object as they count.
  • Introduce the concept of zero through empty containers.
  • Celebrate every counting effort with positive feedback.
Supportive Techniques:
  • Ask: “Can you find the number 7 on this chart?”
  • Organize toys in neat lines to support accurate counting.
  • Sing counting songs to make practice enjoyable and memorable.
Note

Children benefit from frequent and gentle practice. Use daily moments as learning opportunities and encourage curiosity about numbers.
