5th grade teacher
I suggest you meet with the teacher and spend enough time to understand what is being taught. The sketching is of "base ten blocks" that are manipulatives used in the beginning of the lesson. The base ten blocks are passed out to the students and are made of plastic or wood. They show place value for the ones, tens, and hundreds. The sketching your daughter has to do is actually a picture representation of the base ten blocks. Draw a square which = 100, a vertical straight line = 10, and a dot = 1. The number 234 would be drawn as follows: 2 squares would equal 200, 3 vertical lines would equal 30, and 4 dots would equal 4.
All of this is supposed to help your daughter understand the place value and grouping and re-grouping involved in division.
It is not confusing if you spend about ten minutes with your daughter's teacher. Have her/him show you the base ten blocks, then have him/her show you the pictures that represent the base ten blocks, and finally have the teacher demonstrate a problem for you.
If your daughter is struggling with this, I suggest you buy her some base ten blocks or borrow some from the teacher.
