Tens and Units

My daughter is having at school now the Tens and Units..so i am trying to find the matching activtiy in the montessori to help her understand and i am sure that it is more fun with the montessori..and i see this can be the problem when a child is attending a normal school because any curriculum doesn't go like the montessori. the montessori covers everything in all subjects by turn or how can i say it...ahh nothing is skiped in montessori when we start fraction we go along with fraction with everything...maybe one can take time in a step but this too is very important because i don't skip any step if i am not sure that the child did understand the whole concept..but with normal school curriculums they start the fraction and than they leave it..my daughter took half and quarter and that was it....and maybe the next time they will do the fraction can be in year 2 or something and till than she maybe did forget the idea..but with montessori the activity is there all the time, the child can do it again and again so the child will not forget what fractions are, and maybe covers ather steps in the fraction beside doing everything else in the other areas...i don't know if my idea is clear enought...hope it is..

So in this picture we used the activity from N from the Learning ark to practice the Tens and Units...

My problem is that i most of the time don't stick to the montessori orders as for mats and directions and so...and that is because i am not trained, and if i stop till i get trained and understand and do everything as in the book i won't ever start...so please if you see wrong directions or no mats or somethings like that please tell me if it influences the activity or the understanding of the child so i can correct myself as good as i can..
