[TOMT][WEBSITE][2000s/2010s] UK/London children’s internet explorer website

Im almost 90% sure that this was a London based thing as I’m beginning to find out a lot of the websites I used in primary school were mostly or solely for London based Primary schools, but it was this educational website that I believe had all sorts of activities and ways of looking up things that was designed to be suitable for children. It wasn’t purple mash or Busy things which we also used, I remember it being designed as almost a browser within a browser. I imagine it was around before I used it (2011 onwards) hence tagging it 2000s. I’m sorry I wasn’t able to give much more information, i probably haven’t used it since 2012/2013. I’m not even sure if it was only available on internet explorer but since that was the only browsing platform we had access to at the time I’m assuming it was. If anyone has any idea what I’m talking about, even the slightest idea or experience using the website please let me know.
