omg we are doing estimating too and get this, mine still counts on her fingers sometimes, but I can SEE her mentally add 2 2 digit numbers super easy...I can WATCH the process on her face and I'm sorry, but I am with the kids...why ESTIMATE why I can just SOLVE it? lol!!!
Honestly, sometimes I too wonder why does my child get a paper with 20 rounding or estimating exercises on it. And it's the same thing about showing the work or READING the instructions and understand like what "explain" the answer means vs "show your work"...bleh...
