Is the material organized in chunks with headings?
Break text into chunks to help the audience remember and group similar information. Chunked information also looks less dense and overwhelming to read.
A “chunk” is the amount of words or numbers that people can hold in their short-term memory and group with other words or numbers. A chunk should be only one idea that people can connect to other, related ideas.
Use headings to organize and label chunks. Headings are sometimes referred to as “advance organizers.” Consider information flow in the material when creating headings and chunks. Headings must accurately reflect the information that follows, or they can distract or confuse the audience.
Headings are visually distinct (in font style, size, and with spacing) from the body text of the document. Leave more space above a heading than below.

If your child is active in sports, make sure he uses the right protective gear for his activity, like a helmet, wrist guards, or knee or elbow pads.
Use the right stuff.
Be sure that protective sports gear is in good condition and worn correctly at all times. For example, avoid missing or broken buckles or worn-out padding.
Practice makes perfect.
Have your child learn and practice the skills she needs for her activity. For example, if she plays football, knowing how to tackle safely is important in preventing injuries. Be sure to safely and slowly increase your child’s activities so she can improve her physical fitness. This can protect your child from getting hurt.
