Today and tomorrow we are going to be recapping the concept of ‘Partitioning Numbers’. We have done this before but some of us found it a little tricky so its good to practise. Partitioning is used to make solving maths problems involving large numbers easier by separating them into smaller units. By using partitioning, it helps us to understand the values of each digit. We use the language of ‘tens’ and ‘ones’ when describing the numbers. We need to start noticing what place the numbers are in as to what value they have.

 

Start by opening the PowerPoint: ‘Place Value’ to understand what a number represents in tens and ones. Go through the slides explain the concept and answering any questions that may come up.

Then open the PowerPoint: ‘What Number is This’ Count up the blocks to work out what number they represent.

 

Then finish with the PowerPoint: ‘Partitioning 2-digit Numbers’ and work out what numbers are missing. Make sure you do not muddle up the tens and the ones. For example: 42 = 40+2 not 4+2!

 

Activity 1: Complete the ‘Warm Up Place Value Activity’ Sheet circling the tens or one’s number as directed.

 

Activity 2: On your whiteboards or some paper at home we are going to be partition numbers using our part whole model. We are going to place the tens number in the left circle and the ones number in the right.  See the example below ‘Part Whole Model Example’ and then have a go at filling out some more using any number between 1-99.
