September 29-October 3, 2008
For the most part, students were unprepared for Monday's quiz. I have made arrangements for a retake Wednesday after school BUT I do not want them to expect makeup for every quiz. Studying is the key to doing well the first time.
Much of our work for the next few weeks requires graph paper so please make sure your student is supplied. I am requiring students to memorize the first 25 perfect squares for a quiz next week so flash cards made of index cards are recommended.
Please continue to monitor the quality of your child's homework.
The link for our curriculum, the Georgia Performance Standards, is below if you would like to take a look. Feel free to contact me with any questions or concerns.
