When you teach numbers to children, they will give you lots of questions that sometimes do not make sense but can be used as logic when positioning yourself as children. When teaching numbers in sequence, sometimes a question about the highest number. Therefore, teach them the basis of numbers and the value of each number. So it will be easier for children to understand when you answer with "the highest number is the last number of a sequence of numbers in a row". If you use the hundred charts to help them understand numbers, you can answer 100 as the highest number.
Sometimes if children start to get tired of learning, they will ask how to end this. Likewise with numbers. What about an end from numbers? Both children and adults are wondering about this. The answer is no. Numbers have no end or are often called an "infinity". For children, you can add an explanation that "numbers do not have an end, but the math class has an end if they can behave when learning in class".
Learning numbers will not be separated from the chart. Because charts make it easy for children to understand every number that exists. Charts for numbers are various. There is a number called a chart and also called a hundred chart. Although both contain numbers, the two charts have differences. The number chart is numbers in numerical orders. Usually charts consist of multiples of 10. Like 1-10 and 11-20 and so on. As for the hundred charts, it is a table of numbers from 1-100. A number chart does not always contain rows of numbers up to 100. While a hundred charts certainly reaches 100.
In the hundred charts, you can find lots of tens. More precisely there are 10 tens in a hundred. 10 tens are not meant literally number 10. It means the number of multiples of 10 on the chart. Because the scale is a hundred, 10 tens can be described as numbers 10, 20, 30, 40, 50, 60, 70, 80, 90 to 100 because it can be the result of division by 10. It's kinda confusing if you just learn the theory. How about you make your hundred charts first, then try to prove it directly?
