In this article, we’ll answer the question “what is a number sentence?” and go through everything you need to know about this aspect of elementary math. Additionally, teachers can utilize our selection of number sentence in math exercises to assess your child’s abilities.

What is a number sentence?

Primary school children are frequently asked to solve number sentences, a combination of numbers and mathematical operations.

Definition of number sentence is, A number sentence is a grouping of numbers and symbols of two numbers. Questions frequently take the form of number sentences, which are also referred to as “sums” or “problems.”

What is a number sentence

Two groups of numbers known as a number sentence consist of a mathematical operation (such as addition, subtraction, multiplication, or division) and either an inequality ( or >) or an equal sign, sentences with numbers which make sense. It also conveys a fact, just like a written statement. For example, here are some mathematical operations:


  • Addition number sentence: 7 + 5 = 12
  • Subtraction number sentence: 44 – 10 = 34
  • Multiplication number sentence: 5 x 4 = 20
  • Division number sentence: 35 ÷ 7 = 5

When does a number sentence start appearing?

Children usually start learning to write and solve number sentences in the first grade. To assist them in comprehending the value of numbers, they probably start by using items like counters and little toys.

To understand the question, children must also be able to translate word problems into number sentences and understand the number bonds. Here is a number sentence example:

Jay buys lunch for $4.50 out of a total of $10. How much still does he have?

The calculation is 10 – 4.50 = 5.50.

So, using a math number sentence, a child can figure out that Steve has $5.50 left.

Since they make up most of the mathematical problems children encounter, they must learn them early.

Proper Number sentence definition can be”mathematical statements” in the National Curriculum; these are taught in Year 1 and require students to read, write, and comprehend number sentences containing the signs for addition (+), subtraction (-), and equal (=)sign with the numbers in sentences.

  • Students in Year 2 use the multiplication (x), division (x), and equals (=) symbols or (+) addition sign to write mathematical statements for multiplication and division within the multiplication tables.
  • Year 3 uses their knowledge of the multiplication tables to create and compute mathematical statements for multiplication and division, including those involving two-digit numbers multiplied by one-digit numbers, first mentally and then formally in number sentences, with the teacher’s help.
  • To increase fluency, these students keep working on their ability to recall multiplication tables when calculating mathematical statements with the teacher mentally.
  • For example, utilize the distributive law 39 7 = 30 7 + 9 7 and the associative law (2 3) 4 = 2 (3 4) when having fourth-graders make assertions concerning the equality of expressions.
  • Student in year 5 should be able to make equivalence number sentences using the terms factor, multiple, prime, square, and cube numbers (for example, 4 x 35 = 2 x 2 x 35; 3 x 270 = 3 x 3 x 9 x 10 = 92 x 10).

Ever wonder how many words in a paragraph? This question is pretty obvious as a writer. Randomly, we can say a paragraph should be between 100 and 200 words long. But a paragraph’s word count is dependent.

There is no absolute law. However, the word count varies depending on the type of writing, paper length, writing style, and subject matter


Young children should be encouraged to develop mathematical thinking since math is vital. Compared to early reading or attention abilities, a child’s math teaching at the beginning of kindergarten is more remarkable progress for later academic success. Children use math in their daily lives.

When writing essays, have you ever wondered what the difference between Footnote and Endnote was? Students are typically given research papers to complete as part of their academic writing course in high schools and colleges, where they must distinguish between endnotes and footnotes. It is a component of the in-text citation format for a research article.

 Additionally, quotation marks, citation style, etc., change significantly between endnotes and footnotes. The fact that footnotes appear at the bottom of the cited page and footnotes appear at the end of the page is vitally important.

How to write the number sentence

Here are three steps to writing a Sentence with a Number:  

  • Spell out numbers at the beginning of a sentence. Instead of using numerals (e.g., 1, 2, 3), spell out numbers (such as one, two, and three) at the beginning of sentences.
  • Don’t Start a Sentence with a Big Number.
  • Before beginning a sentence with a number, check your style manual.
What is a comparison number sentence?

The comparison of numbers establishes the similarities between two numbers and determines which number is more significant, smaller, or equal to another.

In mathematics, a comparison sentence is an equation or inequality that uses the equal sign or an inequality symbol to compare two mathematical expressions.

We can write 40 < 80. Since 40 is the smaller number, the symbol for less-than points at that number. We can also write 30 + 10<  80 since 40< 80.

What is the recommended maximum number of words for a sentence?

The majority of sentences shouldn’t be longer than 30 or 40 words. According to Proust, “medium-sized” refers to tiny. Most sentences should be 30 or 40 words. Your readers’ attention spans are short, and they get tired.
