Identify numbers from 0 to 5
Identifying numbers means recognizing a written number and knowing its name. The written symbols 0, 1, 2, 3, 4, and 5 are called numerals. Each numeral has a number name and represents a quantity.
Look at the number cards. Each card shows a numeral, its number name, and a group with the matching number of blocks.
- The numeral 0 is called zero.
- The numeral 1 is called one.
- The numeral 2 is called two.
- The numeral 3 is called three.
- The numeral 4 is called four.
- The numeral 5 is called five.
Practice saying each number name while looking at its numeral. A numeral is the written symbol; a number name is the word you say. You can recognize a numeral even when no objects are shown beside it.
Recognizing the numeral 0
The numeral 0 is called zero. It represents a quantity of none, or no objects in a group. Its shape is usually an oval or an oval-like loop.
When a group has no objects, its quantity is zero. The numeral 0 is still a number even when there is nothing to count.
Look at the empty basket. There are no apples inside it.
The basket contains zero apples. The numeral 0 tells us that there are no apples in the basket.
Zero does not mean that you forgot to count. It means that the quantity is none. If a group is empty, you can say, "There are zero objects."
Recognizing the numeral 1
The numeral 1 is called one. It represents exactly one object. The numeral 1 is often written as a straight line, sometimes with a small slanted line or a base, depending on the font or handwriting style.
Look at the picture. There is one ball.
The picture shows one ball, so the matching numeral is 1.
One means a single object, not two or more. Look at the numeral and say "one." Then check whether the group contains exactly one object.
Recognizing the numeral 2
The numeral 2 is called two. It represents a quantity of two objects. In many printed styles, the numeral 2 has a curved top, a slanted middle, and a short horizontal base.
Look at the two stars. Count them one at a time.
- Point to the first star and say, "One."
- Point to the second star and say, "Two."
There are two stars, so the matching numeral is 2.
Say "two" while looking at the numeral 2. When counting two objects, touch or point to each object once so you do not skip one or count the same object twice.
Recognizing the numeral 3
The numeral 3 is called three. It represents a quantity of three objects. In many printed styles, the numeral 3 has two curved parts that face to the right.
Look at the three apples. Count each apple once.
Count "one, two, three." The group has three apples, so the matching numeral is 3.
The numeral 3 has two curved parts in many common fonts. It may look different in handwriting or in another font, but it still represents three. Practice recognizing the numeral in more than one style.
Recognizing the numeral 4
The numeral 4 is called four. It represents a quantity of four objects.
Look at the four toy blocks. Each block counts as one object.
- First block: one.
- Second block: two.
- Third block: three.
- Fourth block: four.
There are four blocks, so the matching numeral is 4.
Four objects do not have to be arranged in a square. They may be in a line, a circle, or a scattered group. Count the objects rather than relying on their arrangement.
Recognizing the numeral 5
The numeral 5 is called five. It represents a quantity of five objects.
Look at the five flowers. Count each flower once.
The group contains five flowers, so the matching numeral is 5.
Five is the greatest number in this lesson. Practice saying the number names in order: one, two, three, four, five. Remember that five always represents five objects, even when the objects look different.
Match numerals to groups
A quantity is how many objects are in a group. To match a numeral to a group, count the objects and choose the numeral that tells how many there are.
Zero matches no objects, 1 matches one object, 2 matches two objects, 3 matches three objects, 4 matches four objects, and 5 matches five objects.
Which group matches the numeral 2? Count the dots in each group.
The middle group has two dots. It matches the numeral 2.
Do not choose a numeral just because a group looks bigger or smaller. Count the objects and compare the total with the numeral.
Recognize numerals in different sizes and colors
A numeral can be large or small, thick or thin, and printed in different colors. These changes do not change the number it represents. Focus on the shape of the numeral rather than its color or size.
Each symbol below is the numeral 3, even though the symbols look different in size and color.
All three symbols mean three. Their color and size do not change their name or meaning.
You may see numerals on books, calendars, classroom labels, and number cards. Look at the shape to identify the numeral, even when it appears in a new place or style.
Tell numerals apart by their shapes
Numerals are different symbols, and noticing their shapes can help you recognize them. The shapes described here are common, but fonts and handwriting may vary.
- 0: usually a closed oval.
- 1: usually a straight line, sometimes with small extra strokes.
- 2: often has a curved top and a slanted middle.
- 3: often has two curved parts.
- 4: often has straight lines and an angled part.
- 5: often has a top line and a curved lower part.
Look at the six numerals. Point to each one and say its name.
The numerals have different shapes. Each shape has its own number name.
If two numerals are hard to tell apart, pause and look carefully at their shapes. Say the name of each numeral aloud. It is normal to need practice when learning new symbols.
Put numbers in order from 0 to 5
Numbers can be arranged in a sequence, or order. When you count forward from zero to five, the numbers are 0, 1, 2, 3, 4, 5.
Each number after zero is one more than the number before it. Learning this order helps you remember the number names and notice when a number is missing.
Follow the number path from left to right and say each number name.
The correct order starts with 0 and ends with 5.
Point to each numeral as you say its name. If one number is missing, say the sequence slowly to work out which number belongs in the empty place.
Check your number recognition
Use a simple routine to check your work: look at the numeral, say its name, and count the objects if a group is shown. Then make sure the numeral and the number of objects match.
Check whether the group of four stars matches the numeral 4.
- Look: Find the numeral 4.
- Say: “Four.”
- Count: “One, two, three, four.”
- Check: Four stars match the numeral 4.
If the number and the group do not match, count again and check the numeral. Mistakes are a normal part of learning. Careful practice helps you improve.
