If your third-grader is spending an hour and a half on just her math homework, for instance, that's way too much. “Keep track of her time for several days, then talk to the teacher,” suggests Dolin. Sometimes teachers honestly underestimate how long an assignment will take. If your child routinely works long hours because she's struggling, also talk to the teacher. But if she seems to be slaving over homework because she's a perfectionist, you may need to discuss a reasonable amount of time to devote to an assignment and then clock her.
The Shang Dynasty is the first historic dynasty of China . The river valley of the Yellow River provided a fertile area for this civilisation to develop. The area was forested and the Shang used wood to build their homes and public buildings; little has survived of their domestic architecture. Fortunately royal and other tombs have provided many clues as to life under the Shang. Artefacts such as beautifully carved jade and stone, bronze ritual vessels and weapons and domestic items such as the earliest glazed porcelain and woven silk testify to their levels of craftsmanship and artistry.
