If you have a programmable embroidery machine, these may be of interest:

Snap! is Berkeley's extension of Scratch which was developed by MIT's Lifelong Kindergarten group -lol:
You can also make use of a turtle library or module when programming in Python. The lifelong learning site Brilliant offers a course in Python which utilizes turtle(), but I think it is a bit too advanced for most 11 year old children (and it is not free). However, you could take this course yourself and use it to help your daughter create original math based embroidery designs.
Some other options which teach the sort of ordered thinking needed in coding and are fun for kids that age are animation and music making tools. I recently worked with 3rd graders who were making animated storybooks and the kids who were digging deeper to do something really different or cool with their project were thinking in a manner not unlike professional coders. My daughter is 28, but one of the best birthday/slumber parties I threw for her was when she was 11 or 12 and I bought her what was then a fairly advanced studio tool meant for adults, and the girls were up all night burning their CD.

One activity I sometimes do with children as young as 4 or 5 is the Robot Game. I gather the children on the carpet and we work together to choose movements to associate with large dots of different colors. For instance, green dot = hands on your head and pink dot = stick out your tongue, etc. Then with large chart as reference, I pair the kids up with one partner being The Robot and the other partner being The Programmer (we discuss the meaning of this word first.) Then I hand out long strips of blank paper on which The Programmer draws an ordered line of colored dots which The Robot then acts out. The kids love this game, most of them catch on very quickly, and many of them immediately jump to coming up with their own creative variations on the theme.
Another game I used to play with my own children was Treasure Hunt. I would hide a series of puzzles around the house with the answer to each puzzle being the location of the next puzzle ending with a prize. You could try combining the Robot Game with Treasure Hunt at a level of sophistication appropriate for an 11 year old and I think that would be great fun for her and her friends, especially given that you have a whole farm over which to direct movements and hide clues. You could even have some of the clues be in code or cryptography which they would have to use a computer to run or decode. etc. etc. etc.
