Your child is heading to first grade! After the year in kindergarten, your first grader will be ready for some amazing growth. For many children, first grade is the year that they bloom as readers and mathematicians. Get ready to support your child’s mathematical growth by learning about first grade math skills.
In first grade, you can expect your child to learn about:
1. Addition and subtraction facts to 20
Now that your child has mastered the idea of adding and subtracting, they’re ready to practice math facts. This means getting faster when answering addition and subtraction problems to 20.
Help your child develop fluency by asking basic addition and subtraction problems - we find that using treats can help keep kids interested! If your first grader needs support, encourage the use of physical objects or fingers as problem-solving tools.
2. Addition and subtraction as inverse operations
Your child probably understands the concept of addition as “putting together” and subtraction as “taking apart.” In first grade, children are encouraged to see the connections between addition and subtraction. Your child will learn how addition and subtraction are inverse operations, or that one is the opposite of the other, and create “fact families” of related addition and subtraction problems.
When working with addition and subtraction, ask your child to see connections. For example, if your child has four dolls and three cars, ask how many toys there are in all. Then ask how many toys there would be if the four dolls are taken away.
3. Count and write within 120
Your child has probably mastered counting to 20. But in first grade kids will learn to count all the way up to 120! That’s not all. Kids will be expected to not only count, but write, the numbers.
This is great practice for understanding multi-digit numbers.
At home: Encourage your child to write numbers whenever possible. Talk about how two-digit numbers are made up of tens and ones and how three-digit numbers are made up of hundreds, tens, and ones. Just looking closely at multi-digit numbers together can be a great learning opportunity.
4. Add within 100
Now that your child has an understanding of numbers past 100 as well as basic addition and subtraction facts, it’s time to practice adding within 100. Children will practice adding one-digit numbers to two-digit numbers using strategies like counting on and number charts. Children can practice adding larger numbers with the help of a 1-100 chart.
First graders are also ready to practice adding and subtracting 10s to and from two digit numbers.
At home: Help your child see patterns when adding and subtracting 10s. For example, after solving a problem like 59 - 10 = 49, point out to your child that 49 has one less 10 than 59.
This is another great way to learn about place value.
5. Measure objects
In first grade, kids learn how to measure using rulers and more unusual things like paper clips. After taking measurements, children compare and order objects by length.
At home: Kids love measuring things around the house, so keep a couple of rulers handy. Pay attention to how your child is using a ruler and taking measurements. Sometimes kids don’t quite measure from end to end, so they might need a bit of help...
6. Tell time to hour and half hour
One of the trickiest concepts first graders will learn is to tell time. Using analog clocks is confusing, especially when kids are more used to seeing digital clocks. In first grade, your child will learn about the big and little hands of a clock and will practice telling time to the hour and half hour.
At home: Get hold of an analog clock for your home (either a real one or one made just for learning). Talk with your child about the time and how the hands move around the clock. Remember to just focus on telling time to the hour and half hour to start!
7. Understand basic fractions
First graders also get an introduction to fractions as equal shares. They will learn how to divide into equal groups and learn basic fractions like ½, ⅓, and ¼. First graders usually have a good understanding of fairness, so practicing making equal shares should be a relatively easy task for them!
At home: Help your child to divide pizzas, pies, and sandwiches into equal shares. As you do, talk about the fractions of the whole that you created.
First graders are ready to dive deep into mathematical concepts. Find time to connect with your child about classroom learning and get ready to have some fun!

How to get a child interested in mathematics?
Mathematics is a wonderful science that surrounds us everywhere.
It not only develops analytical thinking, but often helps in life situations. In practice, the ancient Egyptians understood this. No wonder a responsible parent wants to see their child love math. The science of numbers is considered to be one of the most ancient teachings. The need for an account arose when there was no writing yet, and people wore loincloths. Here is the first interesting fact about mathematics for elementary school children. Parents, take note! How to captivate a child with mathematics?
How to captivate a child with mathematics?
Primary school teachers often simply do not have enough time to tell something other than the program. The school tries to captivate the child in its own way, but you, dad or mom, can give the kid the opportunity to really fall in love with the science of numbers by talking about the most unusual and exciting in the history of mathematics. If you are wondering how to interest a child and reveal to him all the beauty of numbers and signs, then our selection of interesting facts about mathematics for elementary school children will become an indispensable and affordable tool.
Let's go to surf the arithmetic spaces together.
Elementary School Math Fun Facts
Elementary School Math Fun Facts
- The first fact on our list is that the centillion is considered the largest number in the world that has a name.
- Italian scientists have found that fish have mathematical abilities. Previously, these creatures were known to be able to distinguish large schools from small ones, but there was evidence that they could even count the number of fish swimming around. True, so far only up to 4.
- Some animals can also count, such as dolphins and monkeys.
- Mathematics did not know the "=" sign until the 16th century. It was first applied by the British mathematician Robert Record.
- An interesting fact about famous mathematicians is that most of them misbehaved at school. Although it is better not to tell the child.
- World Mathematics Day and April Fool's Day are celebrated on April 1st.
- The magic of numbers is reflected not only in the beauty of equations, but also in the attitude of different peoples towards them. All over the world there are many superstitions on this subject. The most interesting of them: the number "7" is considered the happiest among people from different countries; in many Asian countries, the number "4" is not used, since it is consonant with the word "death"; in the West, the number "13" is credited with an unfortunate influence, so many buildings do not have a 13th floor.
- By the way, the belief about the unlucky number "13" came from the Bible. All because of the Last Supper, which was attended by 12 people, including Jesus Christ. The 13th was Judas, who turned out to be a traitor.
- There is a concept of "Euclidean geometry". This ancient scientist formulated his ideas about mathematics in the book "Beginnings". Euclid's conclusions were considered absolute truth for almost 2,000 years, until Lobachevsky proved in the 19th century that Euclid's axioms were not so universal.
From that moment began a revolution in science. - Mathematics is definitely an exact science. However, history shows that there is a place in it for fateful accidents. There is a story about a student who was late for class. He saw several problems on the board and thought that they should be solved at home. The equations caused him difficulty, but he solved them anyway. This is how easily and simply an ordinary student was able to find answers to problems that the greatest minds of the world had been struggling with for several decades. The name of this student was George Dantzig, who later became one of the founders of linear programming.
- The word "algebra" in all languages sounds the same - a fact!
- Abraham de Moivre - English mathematician - invented a formula by which he was able to predict the date of his own death. Or did the scientist believe in his prediction so much that he could not justify it?
- An interesting fact is that chewing gum improves math skills.
American scientists set up an experiment, during which it turned out that those students who chewed gum, passed the exam in mathematics better. - Mathematicians are not just armchair old men or “nerds” with glasses. One of the great mathematicians of antiquity was a four-time Olympic champion. He even received a laurel wreath for winning a fistfight. The name of this scientist is Pythagoras of Samos.
- A little earlier we talked about folk superstitions related to numbers and highlighted the most common of them. But if we talk about unusual and confusing beliefs, then the Italians are in the lead. In Italy, the number "17" is considered unkind. And all because in ancient Rome on the tombstones they often wrote "VIXI", in the translation "I lived." The vast majority of the population was illiterate, so the inscription and the Roman numeral (XVII) were often confused. As a result, the number "17" became associated with death. Italians are not only afraid of Friday the 13th, but also Friday the 17th.
Future Albert Einstein
According to the editors of the news portal "Centropress" , the facts listed in the article, of course, are far from all that mathematics can offer. Over its centuries-old history, science has acquired many interesting stories and legends. How many discoveries and turning points that turned the world upside down! Mathematics is truly the queen of sciences. Pass on to your child the love of this exciting knowledge, interest and encourage him. Who knows, maybe the future Einstein is growing up in your family?
Interesting facts about mathematics
Every day we have to deal with mathematics. And this is not surprising, because it is no coincidence that she is called the queen of sciences. Numbers follow us everywhere and without them it is impossible to imagine the modern world.
Now we will look at the most interesting facts about mathematics that will be fascinating for everyone and understandable even to children.
In general, it must be said that scientific facts are always very interesting and useful for development.
- A moment is an amount of time equal to 0.01 seconds.
- The sum of the digits of 18 is half of itself. In this regard, it is the only one of its kind.
- Hypatia of Alexandria is believed to be the first woman to do mathematics.
- The equal sign appeared in the 16th century.
- If you add numbers from 1 to 100, you get 5050.
- In Taipei, Taiwan, residents are officially allowed not to use the four, because in translation this figure means the word "death". Moreover, in many buildings there is no 4th floor, and after the third floor immediately comes the 5th floor.
- The famous mathematics professor Stephen Hawking, our contemporary, repeatedly said that he studied mathematics only at school. When Stephen taught at the university, he simply read the textbook in advance, according to which he was going to teach students.
- Sofya Kovalevskaya Curie had to officially enter into a fictitious marriage in the name of science. This was due to the fact that in the Russian Empire women were forbidden to conduct scientific activities. As a result, the only legal way to pursue science was her marriage. Read interesting facts about Kovalevskaya here.
- Despite the fact that very educated people lived in the Roman Empire, the number 0 did not exist in their mathematics. How they managed without it is hard to imagine.
- And you might have heard this interesting fact about mathematics somewhere. George Dantzig, when he was still at university, was late for a lecture one day. When he saw some equations on the blackboard, he mistakenly took them for homework. When he got home, he solved them, although he found the task rather difficult. Bringing them to the next lesson, he learned that these were 2 tasks that until that moment were considered unsolvable despite the fact that the best minds of the planet had been fighting over them for many years.
- In 1900 absolutely all mathematical calculations could fit in 80 books. To date, mathematics is so advanced that it can hardly fit in books exceeding the specified figure by 100 times.
- Negative numbers only appeared in the 19th century.
- The ancient Egyptians did not use fractions.

- Euclid left after his life many works on mathematics, which we still use today. An interesting fact is that no information about Euclid himself was found.
- Rene Descartes (see interesting facts about Descartes) introduced the concepts of real and imaginary numbers.
- Mathematicians are not awarded the Nobel Prize in Mathematics, because Alfred Nobel himself wanted it so.
They say that one of the mathematicians took his wife away, so Nobel was not disposed towards this science. - An interesting fact is that the great emperor Napoleon Bonaparte left some mathematical works after his death.
- Indian scholar Budhayana, who lived in the 6th century, is considered the first to use the number pi.
- Jan Widman was the first to write down the classical signs of addition and subtraction. This happened about 500 years ago.
Interesting facts about mathematics for children
