Here are some of the math-related activities that I have been doing with my 26 month old:
1. She has mastered all the basic 2D shapes in English and Chinese. So I printed out these 3D geometric shapes on cardstock:

Then I made labels in English and Chinese and play a game with her where she matches the names of the geometric solids to the models.
2. I printed out these free number printables and let her color/trace/circle the number. Since my daughter can already read, I just guide her in reading the instructions and following the directions. Here is a sample for learning about the number 1:

I taught her how to press the correct answer on the keyboard and then press "Enter" and she gets a gold medal on the site after successfully completing a section. There is a limited number of questions you can answer per day if you are not a member (which I am not) but that actually works for me because I don't like her spending too much time punching keys on the computer. I let her complete one section under one category per day which takes less than 5 minutes.
