# In math what is 1 out of 22

This article gives you an overview of the math topics in grade 1 in elementary school. First there is the list of topics. Afterwards we take another look at what we mean by the respective topics, whereby there is also the link to the respective topic again. For all content, we also offer tasks or exercises with sample solutions in the respective articles.

These are the common topics in math class for grade 1 in elementary school. Under certain circumstances - depending on the federal state - slightly different content can be dealt with. However, if you can do all of the articles above, you should also be able to deal with slightly different content. In the next section we will then look at what exactly is covered in the respective topics.

### Math grade 1 free content

We already had a list of topics for class 1 of mathematics above. Now let's get down to the issues themselves and briefly explain what they mean.

• Count forwards + backwards: Pupils should be able to count forwards and backwards. For example, count upwards with 1, 2, 3, 4, 5, 6 and so on and count downwards with 9, 8, 7, 6 and so on. We deal with a number of examples with explanations. Further details can be found in our article Counting forwards + backwards (counting on).
• Count in steps: Pupils should also learn to count in steps in the first grade. For example, it is about always adding +2 to a number or subtracting -3. Such types of tasks are sometimes also solved in recruitment tests by applicants. Here, too, we provide examples and explanations in an article. Go to article Counting in steps.
• Neighbor numbers: What are neighbor numbers actually? In elementary school - especially in the first and second grades - you gave a number and now look for the number before and after it. So we take the starting number and calculate +1 once and -1 once for it. Sometimes there are also tasks where only the next number or the previous number is searched for. Continue to neighbor numbers class 1 / elementary school.
• Smaller, bigger and the same: Is Max or Lukas taller? Is Sophie smaller than Anna? In real life, comparisons are often made. And that's exactly what you do every now and then in mathematics. You have to be able to express this somehow. That is why special symbols have been introduced for this in mathematics. We would like to cover three of them in this article, namely less than, greater than and equal to. Go to Smaller, Bigger, Equal: Compare Numbers.
• Plus tasks and minus tasks up to 20: In order to solve plus problems in the number range up to 10 or in the number range up to 20, you first have to know these numbers at all. This is exactly what we will start with in the next article. Afterwards it is a matter of calculating simple plus and minus tasks with these numbers. Continue to plus and minus tasks up to 10 and 20.
• Double and halve: Mathematics is sometimes about doubling or halving numbers. This is exactly what we would like to deal with in more detail here. Let's start with doubling: To do this, you take a number and add the same number to it again. When cutting in half, we reverse the step. We'll look at examples of doubling and halving right away. Continue to double and halve.
• Reversal tasks: What are reversal problems? In the case of an inverse problem, you transform an addition problem (plus problem) into a subtraction problem (minus problem). The numbers used are the same. In grade 1 and grade 2 of elementary school, calculations are often made in the number range up to 20. Go to Reversal Exercises Class 1 + 2.
• rows of numbers: Let's just start with the basics of number series. We have a series of different numbers that are related. A very simple series of numbers would be: 1, 2, 3, 4, 5, 6, 7. Here is simply counted, i.e. always +1. Of course, this also works in the other direction (always calculate -1). Go to series of numbers class 1 + 2.
• Number pyramid, number tower or number wall: Already in the 1st and 2nd grade of elementary school, mathematics lessons are used with number pyramids, number towers or number walls. This is a slightly different representation of arithmetic problems. What do we understand by these terms? Well, unfortunately, many people understand it to mean somewhat different things. If you look around in search engines, then sometimes toys come out. More on this under number pyramid, number tower or number wall.
• Learn to read the clock: There are basically two different types of clocks: analog clocks and digital clocks. We want to look at both types here. Before that, however, it should be clear to everyone how a day is structured. Say what seconds, minutes and hours are all about. We look at analog and digital clocks under Learn to read clock.
• Arithmetic with money: Of course, calculating with money first of all requires that you even know what money is available. So let's first take a look at which coins and notes exist in the euro. Let's start with the euro coins. There are 1 cent, 2 cents, 5 cents, 10 cents, 20 cents and 50 cents. Also 1 euro and 2 euros. On to arithmetic with money.
• Geometry class 1: The first basics of geometry are already discussed in the first grade maths lesson. First of all, it's about getting to know a few simple shapes. So will just do this here too. These are all flat shapes. Typically, these four shapes are discussed first: triangle, circle, square and rectangle. Go to the article Geometry class 1.
• Even and odd numbers: Let's take a look at what we mean by even and odd numbers. To do this, let's just start counting: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21 , 22, 23, 24. Then these are divided as follows: Even numbers: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24 Odd numbers: 1, 3, 5, 7 , 9, 11, 13, 15, 17, 19, 21, 23. More on this in the article Even / Odd numbers up to 20 and 50.
• Insert / add arithmetic symbols: Actually, you should still know some important arithmetic symbols and basic mathematical symbols (for example comparison operators) in mathematics. In elementary school - starting with class 1 - the students have to use arithmetic symbols themselves in math lessons. The aim is to make a correct statement. Exactly this is to be shown here in the form of examples for some tasks. Continue to the article Insert / add arithmetic symbols.
• Factual arithmetic: In the case of factual arithmetic or factual tasks, it is usually about solving word problems. Schoolchildren are given such word problems - often in class 1. The aim is to first understand these tasks, make a calculation from them and then calculate them. Usually an answer sentence is also desired. The difficulty for most students is to turn the text into an arithmetic problem. Go to the article Class 1 math.
• Mirror images / mirror axis: Have you ever stood in front of a mirror and looked inside? If so, you saw a reflection of yourself in the process. Mathematics is also about mirror images and how to draw them. This is exactly what we want to do here. As a first example, we simply take a rectangle and draw a red line in it. More on this in the article Mirror Images / Mirror Axis.
• Number line 1st class: The number line is also dealt with in 1st grade. At least this is sometimes done in elementary school. Continue to the number line 1st class.
