Subject: Re: Place value

Many children have trouble visualizing place value.  I would use base
tens blocks (if you have them) to let her make a model of the numbers.
Start small with just ones, then move up to tens and ones.  Let her make the
models to represent the numbers so she can see 5, or she can see 46.  Once
she can make models, let her start doing simple addition and subtracting
with no regrouping.  

After that concept is in place, start with simple regrouping problems.  Let 
her see that you cannot take 4 from  2 unless you regroup a ten into 10 ones 
so you have enough.  Let her continue to use the manipulative support until 
she feels comfortable enough to let it go.  This problem is not uncommon.  
Many children have trouble with this concept.

Good luck !
