Gattegno Tens Chart

I couldn’t find a Gattegno Chart template I liked online, so I made my own.

See editable PowerPoint below containing the following:

  • Black and White and Colour versions,
  • Versions going from thousandths to both thousands and hundred thousands (with a smaller font),
  • Correctly aligned place value positions,
  • Named powers of 10.

Some guidance on their use can be found from the NCETM here:
https://www.ncetm.org.uk/media/8d84e78e986702e/ncetm_ks3_representations_gattegno_chart.pdf.

There are also some good tasks by Chris McGrane using them, that can be found here:

And there is an excellent virtual version on Mathsbot with options for generating fill-in-the-gaps grids, showing standard form representations, and ‘upside-down’ versions:

They can even link to algebra and powers:
