Before the summer gets started and there’s the big switch in schedule, get the whole family together and
come up with an agreement about what free time this summer will look like. Let your kids talk about what’s
meaningful to them. Spend quality time with your kids and involve them in fun and frolic activities.

their calm & composure.
BE AN INTELLIGENT BROWSER
Internet is an enriching resource of knowledge in today’s world. However, the children have to be
motivated to make the right use of it. Hence, guide your child to browse through informative and
instructive websites that are enriching and enlightening for them. Make sure to monitor what your child
watches on the net.
SAVE NATURAL RESOURCES

Useful Tips
Some days it is very difficult to concentrate. You may just not be in the mood to study or maybe it is a certain
topic that you have difficulty concentrating on. Whatever the reason, there are some steps you can take to
help you concentrate.
• If you keep having the urge to get a snack, then get it first, before you start studying. That is the only snack
you get until you're done. You'd be amazed at how much time you can waste going back and forth to the
fridge.
• Remove any other distractions. Turn off the T.V, go into another room if people are talking. Do not take any
phone calls until you are through.
• Try to do your homework early in the day. If you wait until just before bedtime then your brain will be tired
out at the end of the day.
• Finally, don't procrastinate. Your homework won't get done by itself, so you may as well make up your mind
to sit down and do it. Once you're done, you'll be free to get on with other things.
The students are suggested to get the following for the school magazine written by your own creativity :
