Number and Place Value

Learning Intention:To represent a number in different forms 

Learning experience overview:

As a part of our current unit on Representing Number, we have been exploring different ways to show the value of 3 and 4 digit numbers. Each student rolled a nine-sided dice to create their own number, either 2, 3 or 4 digits, depending upon what they felt comfortable working on.  They then used the Think Board, to the right , to demonstrate their understanding by representing their number on a Place Value Chart, in expanded form, and with Base-10 materials (MAB).  They were asked to demonstrate their understanding of the value of their number in terms of numbers that came before/after, 10 less/more, and 100 less/more. 

Prompts/questions/responses:

• Can you show me another way to make that number?
• What would your number be if it was 5 less/5 more?
• Could you make a counting pattern with your number?
• What other numbers could we make with those digits?
• What would be different about each of them?
• Choose one of those new numbers. How could you show it using expanded form?
• What would it look like if you built the number with MAB (Base 10 materials)?
• Could you count back/forwards from your number, in tens/hundreds?

What you can do now, to continue the learning at home from this experience:

• Count forwards and backwards from any given number. 
• Count on from that number in tens or hundreds. 
• Continue to encourage your child to recognise and use numbers in everyday life.  You could use house/shop numbers or number plates to identify odd or even numbers or count on in tens. 
• Create new 3 or 4 digit numbers from a phone number and write them down in order from smallest to largest.
• Practise identifying the values in a number – what is the value of the hundreds?
