Place Value to Hundreds, Tens and Ones

Usual Year Group Learning: Year 2

Apologies for jumping straight in there with the teacher talk!

Although the words Place Value might be alien to a parent your child will most probably understand that it is a way of explaining what a digit represents. We only have 10 digits: numbers 0-9. If we want to show more than 9 then we place a digit in a second column. For more than 99 we use a third column.

Children should learn that the same digit can represent different numbers, ie one could represent 1, 10 or 100. They should also have an understanding of how the numbers relate to each other in size. One fantastic way to do this is to use Dienes blocks, either as objects or as pictures.

Using Deines to add or subtract

Your child should also be familiar with a place value grid and be able to write one, two and three-digit numbers into the grid. By Year 4, your child should be familiar with the place value grid including Thousands, Hundreds, Tens and Ones. As the year progresses their grid will include hundredths and thousandths.

Essential Knowledge
  • Place value grids are abbreviated to Th: Thousands, H: Hundreds, O: Ones (sometimes called Units instead), t: tenths, h, hundreths. The capital & lower case letters in these words & letters are important!
  • Include the language, ‘ten times bigger’ and ‘ten times smaller’. It will help you in later steps!
  • Point out numbers get bigger towards the left of the place value grid
What to ask your child
  • What does the 2 represent in 235?
  • Can you make 374 from Dienes?
  • How many tens in 639?
  • How many more tens do I need to make 659?
