A prime number is one that can be divide by itself and 1. Here’s an activity to help you get the hang of it…
A prime number is a numerical number that can be divided, without a remainder, only by itself and by 1. For example, 17 can be divided only by 17 and by 1, whereas 12 can be divided by 1, 2, 3, 4, 6 and 12 which mean 12 is not a prime number.
Some facts:
– The only even prime number is 2. All other even numbers can be divided by 2.
– If the sum of a number’s digits is a multiple of 3, that number can be divided by 3.
– No prime number greater than 5 ends in a 5. Any number greater than 5 that ends in a 5 can be divided by 5.
– 0 and 1 are not considered prime numbers.
– A number greater than 1 and is NOT a prime number is known as a composite number.
Is a number prime?
To prove whether a number is a prime number, first, try dividing it by 2, and see if you get a whole number. If you do, it can’t be a prime number. If you don’t get a whole number, next try dividing it by prime numbers: 3, 5, 7, 11 (9 is divisible by 3) and so on, always dividing by a prime number.

Heavy duty vehicles that you often see on a construction site are necessary to move objects. Here’s chance to know them better,
Whether it is excavation, dumping or lifting, construction work involves moving heavy loads. While it is not possible for workers to lift tons of weights, heavy-duty machinery and vehicles provide necessary help. Construction vehicles are essential for all types of construction jobs, regardless of the size and scale. Whether it is the construction of a home building, or a large-scale civil or commercial project, these vehicles are a necessity
Bulldozer
The strongest type of vehicle, it is a tractor with a huge metal blade fitted at the front that is powerful enough to drive a massive magnitude of sand, soil, debris and so on. It has an exceptional grip on the ground and can be easily mobilised even on a patchy terrain.
Excavator
It is the most basic activity that takes place at every construction site. Since it is large-scale, heavy excavation equipment is needed. An excavator consists of a bucket, boom, dipper, and a cab that is located on a rotating platform (house). The house sits on the top of tracked or wheeled undercarriage. Excavators come in many sizes; the smaller ones are called compact excavators or mini excavators.
Dump truck
It is one of the most popular types of construction vehicles and is used to dump debris away from the construction site. It is also used to bring additional construction material to the construction site.
Cranes
They are the most useful construction vehicles. They are composed of pulleys and cables that allow them to lower and lift loads beyond the capabilities of humans. They do not just help in lowering and lifting loads, they also move material horizontally.

A nature-based quiz on beauties that appear only during the rains.
Each year, the magic touch of the rains awakens the earth. A kaleidoscope of life springs out wherever there is uncovered soil, especially in our forests. This floral show keeps changing from week to week, as if Nature is on a fashion parade of sorts. Naturalists call these short-lived floral displays, the Ephemeral Flush Vegetation. Here’s a puzzle based on these plants. Find out how many you can identify.
As if a tweenager’s life isn’t puzzling enough, my parents bought me an actual puzzle!
Well, we’re almost at the end of January and my parents’ New Year resolution to pull me and the PB out of the digital world and into the ‘real’ world continues. I thought everyone was supposed to quit on their New Year resolutions by the end of January and revert to their old, comfortable ways. But no, trust my parents to decide that this is the resolution they’re going to see through, no matter what. Their diet and exercise plans, of course, got cancelled on January 2, but torturing the kids is something they seem to have no trouble sticking to.
Check out the slider to fund out how they came up with new ways to torment poor ol’ me.
