I spend a lot of time in the primary grades because a strong sense of numbers is essential for students to be successful in the older grades.   If students do not know their numbers, how can they add and subtract them?   Sometimes, it is hard to understand what is expected at each grade level and all the components of counting and cardinality.  Here is a breakdown of the preschool and kindergarten counting and cardinality standards and activities to help develop those skills.  

What is Number Sense in Mathematics?

Number sense refers to understanding number concepts, operations, and applications of numbers and operations.

Children with good number sense enjoy playing with and exploring numbers.  Counting, putting numbers together, and taking them apart (composing and decomposing numbers) help students become flexible in their thinking. 

Counting to 100

Preschool Counting Standards:

What number should a Preschooler be able to count to?  They need to be able to count to 20.

  • Know number names and the count sequence
    • Count to 20.  (Oral Counting)
    • Represent a number of objects with a written numeral 0 – 5 (with 0 representing no objects). 
  • Count to Tell the Number of Objects
    • Understand the relationship between numbers and quantities to 10
      • When counting objects, say the number names in the standard order, pairing each object with only one number name and each number name with only one object. (One-to-One Correspondence)
      • Understand that the last number name said tells the number of objects counted. 
      • The number of objects is the same regardless of their arrangement or order in which they were counted. 
      • Understand that each successive number name refers to a quantity that is one larger. 
  • Count to answer “how many?” questions about as many as 10 things arranged in a line, a rectangular array, a circle, or as many as 5 items in a scattered configuration; given a number from 1 – 10, count out that many objects.

Kindergarten Counting Standards:

What number should a kindergarten be able to count to? They should be able to count to 100.

  • Know number names and the count sequence.
    • Count to 100  (Oral Counting)
    • Write numbers from 0 to 20. Represent a number of objects with a written numeral 0-20 (with 0 representing no objects).
  • Count to tell the number of objects.
    • When counting objects, say the number names in the standard order, pairing each object with one number name and each number name with only one object. (One-to-One Correspondence)
    • Understand that the last number name said tells the number of objects counted. The number of things is the same regardless of their arrangement or the order in which they were counted.
    • Understand that each successive number name refers to a quantity that is one larger.

Counting to 20 Kindergarten: 

Count to answer “how many?” questions about as many as 20 things arranged in a line, a rectangular array, a circle, or as many as 10 things in a scattered configuration; given a number from 1-20, count out that many objects.

Preschool Counting Activities

Counting Numbers to 20 

Students begin by counting by ones.  They start with a limited range of numbers and increase until they can count to 20.  As students begin to count fluently, introduce the numeral representations for each number name.  Give students opportunities to match the numeral with the number name. (5= “five”)

Use a variety of nursery rhymes, books, and songs to help students associate number sequences with situations that are already familiar to them.

Taking opportunities to count throughout the day- sitting in the car, walking somewhere, or as a movement break with songs helps develop this skill. They are eventually showing the numbers as they count.  

Counting Objects to 10

Say the number name in order as they point to each object.  Some students may find it helpful to move the objects as they count.  Start by counting objects in a straight line, then proceed to organized representations (arrays, circles) and randomly arranged objects.  

Provide opportunities for students to count objects such as buttons, counters, shells, and dot cards.  Ask students to count objects, beginning with a smaller number of items and increasing as students count accurately.  

Use five frames to model lining up objects and help students begin to see patterns that make 5. Then, as students are ready, represent numbers on a ten frame. 

Ask.” How many are there?” to reinforce that the last number tells the number of objects.    Finally, count on to the original number of items by adding one item. 

Represent the Number

Given a number 1-10, count out that many objects to represent the number.   They should match a numeral card with the number of items and count out that many objects given the written numeral.

Given a drawing of items, they should circle a number of items and write the numeral.  In addition, they should be able to draw a given number of items.

Number Sense Kindergarten Activities

Counting to 100 (Oral)

Students begin by counting by ones.  They start with a limited range of numbers and increase until they can count to 100. Then, they begin to match the number name with the numeral. 

They play games and complete activities using numeral cards and parts of the hundreds chart to connect numerals with number names.

Once students can count to a given number, use a section of the hundreds chart to help them recognize the numerals that represent these numbers. Use matching games and activities to help students connect the number name with the numeral. 

Counting Objects to 20 

Continue to provide opportunities for students to count objects in organized and randomly arranged objects.  Students should be able to count up to 20 objects in Kindergarten.

How Many Counting Worksheets and Slides

There are 30 counting Google Slides that have students count the objects in the picture and 18 counting to 20 worksheets. Students count and represent the amount up to 10, then up to 20.

Provide opportunities for students to count out a certain number of objects up to 20. Then, ask students to match numerals with the number of items in the set they have counted.  In addition, give students a numeral card and ask them to read the number, then count out that many items to represent the number.

Count Objects in a Picture Digital Activities

Students love to use technology to learn; it is more engaging with colorful pictures and movable pieces.   It is also easier for teachers to incorporate as a warm-up, small group, whole group, or independent practice. Then, just download the files, and students are ready to start counting.

Counting Everyday Objects

We don’t need to spend hours developing different activities for students to practice counting. Instead, find objects around your house or at the dollar store to count.   I love to use small erasers, toys, and craft materials to count.  

Give students a number and ask them to count out that many erasers, or give them some pom-poms and have them count how many they have.  These counting activities can easily be differentiated depending on the learner.
