Number Patterns are typical math drill that children encounter although most of the time, the obvious is not that obvious.

Patterns are repeated over and over. These could be numbers, repeated lines, colors, shapes, forms and even behavior.

For an example on number patterns, the factors for 2 are the following: 2 4 6 8 10
12 14 16 18 20
22 24 26 28 30

Number patterns are often given in math aptitude tests because it serves to see how students observe the way the numbers in a number series (among other things) relate to each other.

Some examples of number patterns:

Arithmetic Sequences:

1, 4, 7, 10, 13, 16, 19, 22, 25, …

25, 23, 21, 19, 17, 15, …

Geometric Sequences:

3, 9, 27, 81, 243, 729, 2187, …

Cube Numbers:

1, 8, 27, 64, 125, 216, 343, 512, 729, …

Two Saturdays ago, our little Tenderfoot Scout had an all-day City-wide Scouting Movement with his fellow scouters from The Boy Scouts of the Philippines Quezon City Council.

The activities were held at the Quezon Memorial Circle and attended by many schools from Quezon City.

There was a parade of colors before the activities were given. The scouters played games, got acquainted and played more games.

It was a tiring but super fun activity not just for the scouters but for their families as well.

Mabuhay!

Review Notes for 5th grade Science covering Reproductive System.

MALE reproductive system
• Primary male reproductive organs are the testes, enclosed in a suspended sac-like structure called scrotum.

• Each testis has coiled tubes known as seminiferous tubules. Uncoiled, these measure 250meters. Inside the tubules are packs of cells that produce sperm cells.

• Epididymis is a set of coiled tubes (one for each testis) where sperm cells are temporarily stored.

• Vas deferens is a muscular tube that transports the sperm-containing fluid called semen.

• Seminal vesicles are structures attached to the vas deferens beside the urinary bladder.

• The prostate gland is located at the base of the urethra, just below the bladder. It produces part of the semen.

• The channel that carries the semen to the outside of the body through the penis is the urethra.

• Found between seminiferous tubules are interstitial cells that produce the male sex hormones called testosterone. Testosterone is the hormone responsible for the development of secondary male characteristics like facial hair growth and deepening of the voice, among others.

• A hormone is a substance that has a specific effect on a body activity.

Ang sugnay ay lipon ng mga salitang may simuno at panaguri ngunit bahagi lamang ng pangungusap.

May dalawang  uri ng sugnay:

• Ang sugnay na makapag-iisa ay bahagi ng pangnungusap na may buong diwa kahit ihiwalay sa pangungusap.

• Ang sugnay na di-makapag-iisa naman ay hindi nagbibigay ng pinangungunahan ng pangatnig gaya ng ngunit, samantalang, kung, para, habang.

Halimbawa:

• Sugnay na makapag-iisa

1. Ang kalinisan sa kapaligiran ay dapat na panatilihin

• Sugnay na di-makapag-iisa

1. nang maging malusog ang bayan natin.

Ang parirala ay lipon ng mga salitang walang simuno at panaguri. Wala itong buong diwa.

• ang hangin

• ang mga pulis
