Wolfwind, I'm glad to read a first hand account of someone whose young kids learned this concept very young. I will move forward with teaching it. That's a good idea to have her need to count like in your doll example. I would love for her to able to subitize. I haven't tested her with math dots at all. We haven't been consistent with them lately.

Mybabyian, what a great idea to adjust a math program like Mortensen math. I need to go back and read that thread and do more research on the different options out there like Mortensen and Rightstart. How wonderful that your 16 month old is already loving the math blocks. I am going to look into getting some as soon as possible.

We started showing these to our daughter a little while after you posted this, and she loves the videos! She even repeats many of the sounds as she is watching. Thanks for sharing your find! Let us know if you know of any others along the same lines.

Thanks for posting these videos. I look forward to watching them and saving them for future reference for our daughter. My wife and I hope that our daughter loves math and science as much as we do, so we are beginning to collect materials for her.

I am hoping for some guidance for teaching my daughter math concepts. She is 15 months old, and she currently knows her shapes, some directions such as up/down, in/out, etc., and she knows and recognizes numerals 1-10 in any setting (ie. written on paper, foam numbers, and even on signs).  We play a game where we call out a number and she walks over to the number on her foam mat and either points to it or brings it to us. She tries to count things randomly on her own although she says one, two over and over. She also tries to count on her fingers. I'm not sure that she understands one to one correspondence at this point. We haven't worked on it a lot yet. Is she too young? For reference, we are currently doing math dots (hoping to get LM soon). What else can we do to encourage math knowledge?

I wasn't able to pull up the link, but I'm glad I came across this discussion. The first time we let her watch YBCD, she was under a year old, and it didn't seem to hold her interest for very long. However, she really enjoys it now (14 months).  We really like that it goes more in depth than other programs.

Thank you for taking the time to post such an extensive summary! I am still digesting it and thinking of questions.
