How to teach kids addition and counting on? There are different mental math strategies used with kids to educate them when it comes to math.
These different mental math strategies are used to make the whole process of adding or subtracting easier for the kid. The mental math strategy we are bringing in this video is about teaching kids to count on and add. Counting on and addition are simple and easy when the numbers are small, but they might be a little bit more complicated when the numbers are a little bit bigger.
How is this addition method calculated? There are three different steps which the kid will go through: identifying the bigger number, partitioning the smaller number, and using the chunks to count on. Every single step of these helps the child to understand the whole process step by step instead of getting lost midway without realizing what to do.
The first step of identifying the bigger number is for one important reason which is keeping that bigger number in mind and counting on the smaller one, even if it would be with the help of the fingers.
The second step which is related to partitioning the number is important because it makes it easier to count it on fingers or in mind. The third and final step is about bringing those partitioned numbers together to get the final answer out.
There are different mental math strategies used out there for the kids, but partitioning is considered one of the most famous out there.
In addition, the placement or the order of the numbers is not necessary like subtraction and that’s why kids could reorder the equation in order to keep the bigger number at the beginning and not get confused while doing so in mind, and then start counting on the smaller one after the steps that will be dealt with.
Bringing an example to make it easier for the child to understand it. Let us consider that the equation which will need to be solved is 43+21, how will the kid deal with it according to the mental math strategy we have just explained?
First of all, the kid will sort out the bigger number which is 43 and set it aside and in mind. The second part is partitioning the smaller number which is 21 to tens and units, so it will be 20 and 1.
The final and third step is all about combining those chunks so it will be 43+20=63 and 63+1=64. This brings us to the final answer in the whole equation which is 43+21=64.
Talking about those different mental math strategies that are found out there, there is the reordering and partitioning, the subtraction mental trick of partitioning and removal, the counting on strategy that is used with subtraction, addition working on place value, and many more which help in making addition and subtraction much more easier for the child.
Since it is referred to as mental math strategy, parents should understand that kids could start with recording their answers on a piece of paper or even through counting on their fingers, but eventually they should come to the point of doing all these different calculations mentally without going back to recording any of them down.
Practising is important when it comes to learning and that’s why keep trying this mental math strategy with your kids several times before considering them good at it or else not. Kids learn at different paces and some might take longer times than others when it comes to new methods and strategies, so parents should never worry because eventually, they will learn what they are being taught, all that they are in need for is a lot of practice.
Always speak through the steps with your child to let them understand what you are doing and at the same time teach them the vocabulary and terminology used in order to make it easier for them later on, such as letting them know that addition is the same as counting on, plus, combining, etc. so that they don’t get mixed up in the middle of the way and manage to choose the term that is the easiest for them at the end.
