a. Present<strong>at</strong>ion:<br />
Based from the picture of a tropical cyclone, give pupils insight<br />
how it is formed and its classific<strong>at</strong>ions. Its probable effect and<br />
the precautionary measures in order to elicit or minimize<br />
effects, to check wh<strong>at</strong> they gave in review.<br />
Classific<strong>at</strong>ion of a Tropical Cyclone<br />
(1) Tropical Depression – less than 64 KPH<br />
(2) Tropical Storm – gre<strong>at</strong>er than 64 to 117 KPH<br />
(3) Typhoon – gre<strong>at</strong>er than 117 KPH<br />
Express in r<strong>at</strong>io each classific<strong>at</strong>ion by using a color to<br />
compare quantities/numbers.<br />
Ex: 64:1<br />
117:1<br />
64:117<br />
The Philippines is visited by typhoon in a year for almost 25<br />
times. How can you express this in r<strong>at</strong>io?<br />

Based from the r<strong>at</strong>io being formed, let the pupils give an<br />
equivalent r<strong>at</strong>io to form a proportion. Wherein the<br />
product of the means and extremes are the <strong>sa</strong>me or equal.<br />
