Your job is to choose any of the following topics and briefly explain it. You might include an example. Below each topic, you’ll find some WebPages you are encouraged to look at in order to have further information. In addition, there are some questions to help you write down your comment.


TOPIC 1: WHAT IS A FRACTION?
a) What does the numerator/denominator tell you?
b) How is a fraction different from a whole number?
c) What should I keep in mind when asked to graphically represent a fraction?

A Virtual Class on LCM and GCF

Hi, kids.

Are you ready to start a journey into solving word problems that imply either LCM or GCF?

Let’s watch this video together.

This video has sound. Turn on your speakers, or put your headphones on.

Average online time: 15 min

Average offline time: 15 min

After watching the video, solve the problems there posed on your notebook. This will be your exam.
Give your best. See you tomorrow! :)

Netiquette Rules

Hi, Kids. Now, it’s time to talk about Netiquette Rules….I’m wondering if you have heard the term before. In short “netiquette is a set of rules for behaving properly online” (Shea, 1990). So, let’s find out more about it!

Visit any of these three web pages and then post your comments, ideas, thoughts about netiquette rules

SOME IDEAS ABOUT HOW TO SOLVE A MATH PROBLEM

Hi Kids! By the end of this e-tivity, you will be able to

1. Identify the four main steps used to solve math word problems

Average on-line time: 15 min


George Polya, a famous mathematician, designed a method for solving math problems. Let’s take a look:

1. Understanding the Problem
What do I know? What information do I have? What do I have to find out? Can I restate the problem in my owns words?

2. Devising a plan
Have I solved a similar problem? Which strategies can I use: make an orderly list, use direct reasoning, solve an equation, look for a pattern, draw a picture? Do I know other strategy?

3. Carrying out the plan
Let’s work this problem out according to our plan.

4. Looking back
Is the solution a logical one? Did I do all operations properly? What does the result tell me?
