Question

How to teach place value to kids

Answer 1

IMO, teaching someone how to count (and doing it) helps teach place value.

One has to name a lot more numbers to get from 100 to 200 than from 10 to 20. Games like jump rope or hide-and-seek where counting is part of the game can help with this. Certainly in hide-and-seek it becomes clear that counting to higher numbers takes longer.

Playing games with chips or play money where conversions are done back and forth between different denominations can also help with this.

It can also be useful to learn to count by 10s or 100s or 1000s. This can show that the digit to the left of the 10s digit counts the same number of tens that the digit left of the ones digit does of units. That is, the relative positions of the digits have the same effect or meaning no matter where they are in the number.

Answer 2

Teaching 'place value' can be actually tough, especially when teaching somebody this and the have never learned it before at all.

One thing that the student would want to know is what would you want to call the digits before the 'little dot', or the decimal that is in the value.

You could teach them that the number values before the decimal point would all end in 3 specific letters (ths).

And the rows of those would be:


`\left[\begin{array}{ccc}ten\bf(ths)\\hundre\bf(ths)\\thousand\bf(ths)\end{array}\right]`
_____________________________________________________________

And as for the digits above the decimal point, they would be just as "ones, tens, hundreds, thousands, and so on . . ."

This would be a way to teach a person.

I hope this help! :)
