A few weeks ago, right before we all got sick, I had a difficult time with one of Lamb 2's math lessons. I was upset with myself for not being able to handle 4th grade math. I thought I had bought his math book used and figured I could handle doing grade school math and did not need to spend extra to buy a teacher's edition with answer key. I planned to set aside some time to look at it again without Lamb 2 and then sit down with Lamb 2 and redo the lesson. I wondered what my problem was since I didn't remember having trouble with this lesson when Lamb 1 did this book a few years ago. Then we got sick and after we were well I never found time to work on that lesson. My hope was that since it was before we got sick, maybe my brain just wasn't functioning well that day.
Lamb 2 is almost finished with this math book, so I went to get out his next math book today. What a surprise that right by his next math book was the answer key for his current math book! No wonder why I didn't have a problem with this lesson with Lamb 1, if I did, I checked my work in the answer key! When Lamb 2 did this book I forgot that we owned the answer key and I worked all the problems out in my head as he did each lesson. Instead of being upset with myself, I'll give myself a pat on the back that I did 118 4th grade math lessons by myself.
I could blame misplacing the answer key on moving, but unfortunately he began this book last spring and I didn't use the answer key then either. Hopefully I can remember that I own this answer key when Lamb 3 does this math book! Since I own several levels of math books, in the future I am always going to check if we own the answer key before one of the Lambs begins a new math book!
