Therefore, we have created exercises addressing all aspects of the concept to help the students and the teachers.
Number sentence: An overview
Children at the primary/elementary level are often made to work on mathematical problems based on number sentences.Questions based on number sentences comprise numbers and mathematical operations. If you are one of them searching, ‘what is a number sentence?’ Do not be bothered; here is anexplanation.
A number sentence can be defined as a set of numbers and symbols for two numbers.The questions based on number sentences are often called problems or sums.

Two sets of numbers are referred to as a number sentence comprised of a mathematical operation, like addition, subtraction, multiplication or division, along with an equal or inequality sign. Number sentences without a number or a mathematical operation will not make sense.Just like a written sentence, a number sentence also communicates a fact. For instance, examples of a few mathematical operations are mentioned below:
• Number sentence with addition: 6+7= 13
• Number sentence with subtraction: 27-11= 16
• Number sentence with multiplication: 7×6= 42
• Number sentence with division: 36÷4= 9
When do studentscome across number sentences?
Students usually learn to write and work on number sentences in their first grade.Counters and little toys are a few of the items which assist students in understanding the values of numbers. However, they probably are the first items which assist primary-level students in comprehending numbers and mathematical operations. To comprehend the question, students must be able to express word problems into number sentences and derive the bond between the numbers.A number sentence example in words can help you to understand the concept in a better way. Refer to the below example:
Sam has $ 15.50 with him and purchases chocolates for $5.50. How much money does he is left with?
Sam is left with 15.50-5.50= $10.
Hence, by applying the math number sentence, a student can make out that Sam is left with $10 in hand.
Students must understand and learn the number sentence at an early age due to its significant role in all problems based on mathematics.
A number sentence is a mathematical statement which is found in the national curriculum. The children get recognized with this concept during their 1st year in school. After that, they are made to read, write and understand the number sentences accompanied by mathematical signs such as + (addition), – (subtraction), and = (equal), along with the numbers mentioned in the sentences.
Number of bonds and mathematical operations leading to expansion in number sentences
As the student progresses by studying each bond and mathematical operation, the number of sentences also automatically increases.
• Children in grade II learn using x (multiplication), ÷ (division), and = (equal) signs to create mathematical statements for division and multiplication purposes inside the multiplication tables.
• Children in grade III, using their multiplication tables knowledge, generate and work out mathematical statements for division and multiplication involving two-digit numbers multiplied with a single-digit number. The teachers help them to make calculations in their minds and then solve them by using number sentences.
• To become proficient, the students are often made to revise the multiplication tables by their families and teachers.The activity of recalling the tables help them to make calculations in their mind.
• Children in grade IV can frame statements about the equality of expressions; for instance, apply distributive law 12 x 5= 10 x 5 + 2 x5 and associate law (3 x 2) x 4= 3 x (2 x 4).
• Children in grade Vlook forward to solving questions related to term factors, square and cube numbers, multiple and prime numbers, etc. They are expected to use them while constructing equivalence statements, for instance, 20×6= 3x3x20; 270 x3= 3x3x9x 10= 81x 10.
• Children reaching this grade must also identify improper fractions and mixed numbers, change them from one form to another, and create mathematical statements > 1 as a mixed number, for instance, 2/5 + 4/5= 6/5= 1 and 1/5.
• Children in grade VI carry on using all multiplication tables for calculating mathematical statements to maintain fluency.

Why is fluency in math sentences necessary?
Though the term math sentence is relevant to elementary school, its application goes beyond the elementary level as it revolves around equations and inequalities.
• Mathematical sentence expressions help students build algebraic thinking for higher classes.
• Problems based on math sentences can be solved flexibly. For example, students can break the numbers mentioned in the sentence to observe the value of each digit.
• Mastering tables and practising mental calculations have their benefits in the long run.However, expressionsof arithmetic are not conceptual; rather, you need to understand and find the reasoning behind it to apply it in the real world.
Activities helping students learn number sentences.
Students who find number sentences quite difficult or doubt their abilities to solve a mathematical statement should practice more often, which will help build their confidence. It is precisely applicable to students of Grade I. Teachers and parents may find it difficult to develop new and engaging ideas to help students get used to mathematical concepts. Still, they need to cultivate the students’ learning abilities by embracing new methods that can help them master the subject.Through our article, we will research a few of the selected activities and exercises developed by teachers to make the students learn number sentences in a fun way. So let’s start the discussion with the number sentence activities that are kid-friendly:
Ladybug number sentence worksheets
The educators may create number sentences by using the ladybug worksheets. They are adorable arithmetic printable sheets which are blank.They can make a small circle on the blank ladybugs and ask the kids to double the circles by drawing the same number on the other side and adding them. The method is excellent for teaching young kids about true number sentences.
Dinosaur subtraction activity
Dinosaur subtraction activity is a traditional method of teaching number sentences to kids. Different types and colors of dinosaurs attractkidsto solve problems. The activity sheet is a compilation of decorated numerical sentences with dinosaurs replacing the numbers. To finish the equation, the kids must multiply each of the dinosaurs.
Dice addition game
The dice addition game makes kids have fun with arithmetic and engages them in this activity quite easily. Give your kid a dice and ask them to throw twice, entering the digits appearing on the dice each time on the activity sheet. The activity sheet has some blank spaces that must be filled with the numbers appearing on the dice. The activity can be performed in pairs or small groups.
Conclusion
Kids from an early age should be stimulated with mathematical thinking by their family or teachers. Mathematics is vital to academics until the student chooses to opt for his discipline during his higher studies.A kid’s mathematics activity during kindergarten is more impactful and helpful in his later academic success. Mathematical operations can be applied to daily activities to make students attentive and develop an interest in number sentences.
FAQs
How to create a number sentence?
You can follow the below steps to write a number sentence:
• In place of numerals, spell out the numbers at the start of a sentence (use one, two, three instead of 1, 2, 3)
• Never begin a sentence with a large number
• Check the style manual before starting a sentence with a number
How to write a meeting agenda, including essential items?
The following should be on a meeting agenda:
When to use a meeting agenda?
Every meeting—or at the very least official ones—should have an agenda. A meeting agenda is useful if you want to save time, be on the right track, or achieve a certain goal.
Is there something called a comparison number sentence?
Yes, a mathematical concept is referred to as a comparison number sentence. It builds commonalities between two numbers and decides which one is more powerful, smaller, or equal to another.A comparison sentence in mathematics establishes an equation or an in-equation between two given numbers. It uses the symbol equal or inequality to make comparisons.For instance, 25>16 as 25 is a greater number hence the sign greater than is used after the number.This equation can also be written as 20+5>16 since 16<25.
Do number sentences signify being true?
A math sentence doesn’t need to always be true, but each sentence generates certain information. Based on this information, there is a possibility to revise the sentence from false to true.
Can you establish the distinction between equations and inequalities?
A mathematical expression is said to be in an equation when the two expressions accompanying it have equal value. In contrast, inequality in a sentence shows that one expression is more than or less than the other.
Can you write fractional numbers in a sentence format?
Yes, fractional numbers can be framed in a number sentence format, for instance, ⅜ + ⅝= 8∕ 8
