I just gave DD 2.10 the K12 math placement tests just for the heck of it. I was floored....we have never covered any of this, and she got ALL but 1 of the K level right. She missed one on money, but she scored 14 out of 15 on Semester 1 K, and 15 out of 15 semester 2 K. According to this she would be placed in 1st semester of 1st grade math! And it sys to keep testing till they do not pass, which I didn't do. I did not test assesment 3 which is 1st grae 1st semster material, although I printed it out so I will see how she does. Although I am a little scared to give it to her.
Really there were things I have no idea how she knew. Some fractions, and volume, etc. She's not even 3 yet. How will she ever cope in school? Okay. I am guessing I should breath. I really thought she wouldn't pass them. Just was curious to see since she as been self exploring addition and subtraction as of late.
