Lessons to teach 3-digit numbers

lessons to teach 3-digit numbers

The recent audit of readilearn resources for teaching number showed that, while there were many lessons for teaching understanding of number and place value to 100, lessons for teaching numbers above 100 were scant. This is somewhat understandable as confidence with numbers relies upon a firm foundation in understanding the basics of our decimal system. However, it was a situation I needed to remedy.

numbers to 1000

Last week I added 1000 Pancakes to the collection, a lesson to help children visualise 1000 objects by counting in 1s to 10, 10s to 100 and 100s to 1000.

Understanding place value of 3-digit numbers

This week, I added Let’s Count Pancakes β€” 3-digit numbers, a lesson that helps children recognise and represent 3-digit numbers and understand the value of each numeral in its place. The interactive lesson ready to teach on the interactive whiteboard consists of ten different slides ready to discuss with the children.

On each slide, children count the pancakes and write the number of hundreds, tens and ones they count.

They then choose the correct 3-digit number that corresponds. (In this lesson, a stack of 10 pancakes always has a strawberry on the top.) The lesson helps the children see the importance of each place to indicate hundreds, tens or ones.

I have also updated ACARA and readilearn lessons in number to include these two resources.

Remember, there are many other lessons, not only in number, ready for you to teach on the interactive whiteboard. While you are here, why not check them out.

    These are all good resources, Norah. Every time I read your Readilearn posts I wish I’d know about this site when my kids were small. It would have saved me a lot of research effort.

    I would have loved to assist you, Robbie, though I know you’ve done a great job with your boys and both are doing amazingly well as a result.

    A real serve would help us digest the maths even better, wouldn’t it?

    I’ve noticed that older people (like me) are comfortable saying ten hundred or fifteen hundred etc instead of one thousand or one thousand, five hundred, but often kids don’t see the equivalence. I think it’s important to expose them to different ways of describing number as we give them visuals and experiences with quantity and place value as your materials do. I saw kids really getting stuck with place value and think also there is not as much real hands on experiences with money, etc.

    And even older people (like me) have difficulty translating those larger numbers of hundreds to thousands. I think I should have been exposed to more ways of describing numbers when I was growing up, as you say. It is so important that children have a good understanding of place value right from the beginning with 2-digit numbers, or our decimal system will never make sense to them. Hands on experience is vital in helping children visualise and understand quantities.

Please share your thoughts. I love it when you do.
