Numbers to 1000

In my earlier post, I had mentioned about Place value. You may be wondering about its importance. Place value helps pupils understand the concept of numbers. It also helps them when they are comparing or ordering numbers (to be explained in the next post)
In my class, I always ask the pupils to put the digits in their ‘houses’. For instance in 135, 1 is the 100s house, 3 is in the tens house and 5 is in 1s house. So when they read the number, they read as one hundred and thirty-five. This helps pupils who have difficulty recognizing, reading and writing numbers (100-1000).

Refer to the diagram below:



So from this diagram, we have 135 or one hundred and thirty-five.
100 + 30 + 5 = 135

This ‘housing’ also helps pupils when they write the numbers in word numbers and vice versa as they are able to read aloud and write it down.

Parents you may wish to test your little ones in this concept tonight. This site allows them to practise what they have learnt. Please click www.learningbox.com/Base10/BaseTen.html
Remember to click on all 3 buttons on the left so that 1, 10, & 100 is highlighted in green.

Another site http://www.numbernut.com/basic/activities/number_4bar_1-1000.shtml to test their concept on being able to recognize the number words of 100-1000.

Below are some of the pictures. We are extremely lucky and privileged that we have a SMARTBOARD in our class. (thanks toP, VP & IT Dept) The SMARTBOARD, brings the whiteboard to live. It's like having a mouse on the board plus coloured pen plus recorder. Yes, it can record every movement made on the board. Today, I will show pictures and activties that have taken place so far.
