Hi, Lori. My name is Rachel with RightStart and yours is a great question! I contacted Dr. Cotter to get her perspective - answer:-) - for your question. Here is what she wrote:

'First I must apologize to discover there are errors on page 245.

For the first problem on page 245, the thought process goes like this: To find the trial quotient, divide 29 by 4 [ 7 ]. Next to check if 7 will work, divide 290 by 7 [ 41 ] Yes, it works. (Had it been less than 41, we would have had to try 6 as a trial quotient.) So multiply and subtract.

To find the next trial divisor, divide 33 by 4 [ 8 ]. [ 41 ] Yes, it works. Again, multiply and subtract.

It is not necessary to write the division results shown grayed, but it might be helpful for awhile.

I hope this helps.

I also wanted to forward to you the 'corrections' link. When users send in a correction, RightStart changes the manuals/worksheets so they are printed correctly from that point on.
