One of the challenges when developing understanding of decimal place value is to represent the size of the smaller place values in correct proportion.

In this session you will have the opportunity to engage with a fresh approach to introducing decimals (10ths, 100ths and 1000ths) using a combination of number lines, number talks and a specially developed number line template in Excel.

One of the benefits of using a spreadsheet is the visual representation of decimal place value with lengths, the relationships between place values and the ability to use it to address common misconceptions. It also leads nicely into developing understanding of equivalence and rounding.

Print ready templates and the Excel template will be shared with participants.


Key takeaways               

  • awareness of how the spreadsheet template can be used to support students in deepening their understanding of decimal place value
  • a resource that enables students to visualise decimal place values to 1000th in correct proportion
  • understanding of how the template can be used to address common misconceptions
  • a copy of the Excel template
  • printable A3 and A2 templates for students to work with.
