Most children by age 8:
Grow about 2.5in. (6cm) and gain about 7lb (3kg) in a year. May have arms and legs that seem too long for their bodies.

Lose about four baby teeth each year, which are replaced by permanent teeth. Have 20/20 vision. Know how to count by 2s (2, 4, 6, 8, and so on) and 5s (5, 10, 15, 20, and so on).

Know what day of the week it is. However, they do not usually know the full date and year. Can read simple sentences of 2 to 7 words. Complete simple single-digit addition and subtraction problems (such as 1 + 8; 7 + 5; 6 – 2; 4 – 3).

Can tell the difference between right and left. Have a black-and-white perspective much of the time. Things are either great or awful; ugly or beautiful; right or wrong. They focus on one trait or idea at a time, which makes it hard for them to understand complex issues.

Enjoy being around their friends. The opinions of their friends become increasingly important, and peer pressure may become an issue. Gain a sense of security from being involved in regular group activities. Are more likely to follow rules they help create.

Are impatient. They like immediate gratification and find it hard to wait for things they want. Are interested in money. Some children may become obsessed with saving and plans about
earning and spending money.

Have well-developed speech and use correct grammar most of the time. Become interested in reading books. For some children, it is a favorite activity. Are still working on spelling and grammar in their written work. This aspect of language development is not as advanced as oral speech.

Tie their shoelaces. Draw a diamond shape. Draw a person with 16 features. Become increasingly skilled in hobbies, sports, and active play.
