Mental Math Strategies for Children | Near Doubles Addition | Different Mental Math Strategies
The mental math strategy we are going to work on in this educational video is called "near doubles" which is used with addition of very close numbers as a gesture of making it easier for the child to do it all in mind.
The whole idea behind the strategy of "near doubles" is to double the bigger number in the addition equation and then remove the difference between the two numbers from the answer. To make it clearer, if the equation is 7+8 then the steps will be doubling the bigger number which will be 8+8=16 then we know that the difference between 7 and 8 is 1 so we will remove 16-1=15 and this will bring us to the final answer which is 7+8=15.
There are different mental math strategies used with addition but every single one of them depends on the numbers used in the equation. In the case of the "near doubles" equation, the numbers should be very close to one another because kids might get lost in the middle if the numbers are not near and the difference between them is huge.
Since this is a mental math strategy, it means that kids should give their minds the chance to think and consider the answers before giving them. Kids should first think about which is the bigger number, they should consider its doubling answer, they should count the difference between the two different numbers, and then eventually come to the point of removing it from the doubled number. These are different things which the mind will need to think about and consider before coming to the part of answering the equation.
One of the other famous strategies related to mental math and addition is reordering. In addition, kids should learn to keep the bigger number in their heads and count the smaller one on their fingers or through using any other favorite technique like the number lines (https://www.youtube.com/watch?v=Wn2YBpCIzis). So reordering is all about placing the bigger number first and then moving forward to counting the smaller one in mind, on fingers, etc (https://www.youtube.com/watch?v=mdux-Xn35qE).
Addition and subtraction could be both solved in lots of different ways and by using different mental math strategies that will always depend on the equation itself; big or small numbers, big or small difference between the numbers, etc. Also the strategies that are used with addition might not work with subtraction and vice versa (https://www.youtube.com/watch?v=LAlpqGKQOG0).
One of the good strategies that make subtraction much easier for kids is the partitioning one where they choose the smaller number in the subtraction equation, partition it into tens and units, remove the tens from the bigger number and then remove the units from the answer, and this eventually bring them to the final answer (https://www.youtube.com/watch?v=OhWalcCRLX0).
Practicing is very important and parents should always know that when they help the kids to practice more, they will learn faster and easier because practicing is the main rule in learning. Another important thing parents should keep in mind is that kids are different and some might take more time in learning things than others, so parents should never worry and should know that kids will eventually learn everything when they keep learning and practicing on these things they learn.
While teaching your kids subtraction or addition, it is important to educate them about the different vocabulary related to them to give the kids the chance to know what they are supposed to do. For example, addition is the same as combining, putting together, plus, etc. while on the other side, subtraction is the same as taking away, removing, minus and so on. These words are sometimes more understandable by the child and thus give him/her the chance to know what they are supposed to do in order to solve the equation.
Playing games, using mental strategies, depending on the regular old methods and techniques are all different things parents could follow and depend on when it comes to educating their kids and teaching them the different mathematical operations that are found out there, such as addition and subtraction which always come at the beginning after learning to count.
LearningMole focuses on educating children of all ages. We offer advice and practical, interactive ideas to help parents challenge, homeschool, teach and develop their children’s skills at home.
Help your child to progress and explore and most importantly - have fun!
