How To Teach Place Value
Learning place values is very important when you have to do long additions. You have to know all about the ones place, tens place, hundreds place, thousands place and so forth.
Hi. I'm Donald Sinclair. I'm a Science and Maths teacher with Greater London Tutors.
Today we're going to be looking at how to teach various topics. A good way to teach place values is to use tokens of some kind. Here I'm using chips, anything with different colours that can easily distinguish, can be used in their place.
Try to avoid using things like coins because they already have values associated with them. Here, I'm going to use these to represent ones, tens, one hundreds and a thousand. Bring in the idea that these are worth that amount of number rather then representing that.
If you were to take an amount from each pile, ask the child to add up the total worth of these tokens, that would probably be quite difficult. However, you can show the idea that if we have for example, seven 1's, six 10's, two 100's and six 1000's then you end up with the number 6267. And this brings in the idea that when you're writing down a long list of number, each place signifies a certain thing whether it's 1's, 10's, 100's, 1000's, 10,000's, 100,000's and so on.
This is a very basic idea that really helps with manipulating large numbers later on. Place value is a very basic idea in mathematics which is important to learn. It helps you in manipulating large numbers later on.
Here we have a four digit number like this. The first digit signifies the number of ones, the second digit signifies the number of tens, the third digit the number of hundreds, the fourth the number of thousands and so on. Having the basics of place value makes things like long additions lot easier.
Adding 3 digit numbers like this seems daunting at first, but once you have the idea that all you're doing is adding units and tens then one hundreds and so forth, it becomes lost input. So here if we add the units first of all 6+7 is 13, then add tens 5+0 is 5, putting in the tens column and finally 5+9 is 14. Then we can simply add them up.
How many units are there? There's 3. How many tens are there? There's 6. How many one hundreds are there? There's 4.
How many thousands are there? There's 1. So some of the two numbers become 1463. So these are the basic of place value and good ways to teach them ways of addition. .
