Free printable download: Designed to help with 1 more/less and 10 more/less hundred board work. Just cut out the middle square and then down sides so they flap up.
This website is set up and run by me to share resources that I make for the classroom - I am full time teacher. Do look round the site, there are over 700 downloads available. If you find the resources I put up helpful, please share with others.
Do contact me too, if you have any ideas or feedback.
Many thanks, Jo
