Making the right technological decisions for your children

Most parent have the difficult task of taking decisions regarding technology which didn’t even exist when they were children themselves. They go by their instinct to make the right decisions and to understand what is best for their child. Sometimes the whole thing can be pretty confusing and can leave the best of u bewildered. However, the following are a few tips from the expert teachers at preschools in Darwin which would help you arrive at the right decisions.

 

Technology for communicating

You can use the mobile to build connections which can help develop your child mentally and socially. Bring them closer to the family by letting them Face time Grandparents or Skype their cousins and friends. These days there are many families which live far from one another. Technology though has helped bridge the gap. It helps children stay connected to their extended family.

 

Show your child interesting stuff using your computer or mobile

You can show some interesting videos to your children. For example if there is a certain question that they ask you, what better way to explain it to them then showing it on You tube.  Children are highly visual creatures. They can learn a great deal by watching things and it always creates a lasting impact on their active minds. Use the dictionary to learn new words or get to know the spellings of words that they already know. There are games which help facilitate language learning. You could teach your child a language or two by downloading the different language apps. Children love to learn new things and this is one way which you could help them.

 

Get involved with your children

Don’t just handover the mobile or the computer to your child and let them watch it unattended. While it’s an attractive option to ensure that the child stays quiet and involved, it’s important for parents to supervise them at all times. Its better that you involve yourself in what your child is watching. Discuss what the child thinks about the content they just watched. Listen to their opinion and have a healthy discussion with them. This would help develop mental capability in children from a young age and make them feel that their opinions are valued.

 Make them experience the hands on approach

Before you invest in technology in the form of an iPad or a laptop, make sure that your child is involved in activities which teach them a hands on approach. They should show an active interest in reading books, painting and coloring or indulging in physical play. There is no amount of technology which can substitute for all of the above mentioned things. Make sure that any experience they have with the real world is all the more important. In fact if possible try to control the amount of time they spend using technological gadgets. Some experts advise screen time of less than two hours for children. Some consider this as too much. Make sure your child doesn’t exceed the suggested time.

Your Professional Babysitter

Although, most of us may not know this, children in their very early years are like a learning sponge. They will absorb behaviours, language and movement like a sponge in their first formative years; that is between the ages of one to three especially. These are also the years that require parents to watch over them constantly, they cannot be left unsupervised for even seconds when awake and are in the age that requires a lot of running around. In another aspect, soon after the baby is born parents are learning to cope with the new addition, making adjustments in their routine to be able to parent properly and one of the parents will most likely either leave their current job or will not be able to excel in it the way they did before. With this age group being a crucial age for a young child’s development, parents only want to perfect their abilities and have a difficult time managing everything together. What if I told you that it doesn’t need to be so hard to raise kids and excel in your career at the same time?

A few decades ago, the solution would sound ridiculous but today with its wider acceptance, childcare is helping parents all over the world. For those parents completely new to the concept, allow me to explain what it is and what benefits are available through childcare services. To describe it simply, childcare in Toowoomba is a professional and commercial form of babysitting, something we all are acquainted with. What is different between childcare services and babysitting is a marked difference in security, safety and expertise.

Childcare services strictly adhere to regulations that offer a safe and secure place for children, so that parents may leave them worry-free. Staff and caregivers are required to have some sort of formal education and certification that pertains to dealing with children exclusively. They must be free of any criminal record and such related suspicion and meticulous background checks will re-affirm this for all hired staff. The idea is to offer an environment that will also help children learn and engage them in activities good for enabling their skills and aiding their development. This is why parents no longer worry about leaving their children in childcare Toowoomba because the professional services and security is monitored and regulated. With this service parents are able to go to work and focus solely on their jobs in the time that they are away from their children. This has shown to increase efficiency at work, which will eventually lead to promotions, bigger opportunities, career growth and inevitable job satisfaction and security.

This system of happier parents and happy kids has resulted in a new family system with idealistic expectations being met and an overall better quality of life. This is also a solution for children that have no brothers or sisters and tend to get lonely at home. Busybees childcare in Toowoomba offers a place of social interactions, company and a chance for little ones to make friends!

Power Of Square Roots

1. The whole powers

In first and second, you studied the positive integer powers of natural numbers then of integers and finally of fractions and decimals. Until then the powers were positive.

If we can say, the powers have been “invented” in order to simplify the multiplications.

Instead of writing 2.2.2, write 2³.

In third , we move to the higher speed: Arrive the whole powers, so positive or negative while remaining whole. In future years, powers may be fractional.

Note : The negative exponent tells me that I must take the opposite of the designated expression. Thus for example the exponent -3 tells me that I must take the opposite of the expression and then raise this new expression to the cube. A negative power never indicates that the expression considered is negative but simply that we must go to the opposite!

First-degree equations to an unknown

These are last year’s equations in second place. I advise you to review in your course last year the exercises that you had solved and the method of resolution.

You can also do all exercises 1 to 7 on page 38 and 86 to 89 on page 46.

How to solve an equation that seems more complicated, with denominators, large bars of fraction, “less” in front of these bars of fraction, etc.

Click here, you will find ways to learn .

Here are some other equations …. a little more complicated.

Here are the solutions:

 

So far, we are solving equations that admit a single solution. We can say that they are “determined” equations.

Special equations

1) Impossible equations

Either solve the equation: 0x = 4

Question : Is there a number that multiplies by 0 gives 4 as a product? None, of course! 0 being absorbent element for multiplication! This equation does not admit any solution. We will say that it is an impossible equation.

Here is a series of impossible equations.

0x = -3 0x = 78 0x = -56

2) Indeterminate equations

Either solve the equation: 0x = 0

Question : Is there a number that multiplies by 0 gives 0 as a product? Yes of course ! Any number multiplied by 0 gives 0 as product. Any number is therefore solution of this equation. Here is an equation that admits an infinity of solutions. It’s an indeterminate equation .

 

In summary then

An equation has one solution: determined equation

an equation admits an infinity of solutions: indeterminate equation

An equation admits no solution: impossible equation

 

2. The zero-product equations

Reminder : 0 is an absorbing element for multiplication. This means that if a factor of a product is zero, the product is necessarily zero.

Example : 3.5×2,7x0x3,6 = 0 because one of the factors of this product is zero.

Mathematically, whatever the numbers a and b,

If a = 0 or b = 0 then ab = 0

Reciprocally , we will admit that if a product is zero then at least one of its factors is necessarily zero.

Mathematically, whatever the numbers a and b,

if ab = 0, then a = 0 or b = 0

Example :

Here is a zero product: (x + 2) (x + 3) = 0. This product has two factors. Since the product is zero, it is because one of the two factors of the product is necessarily nil. Let the first factor (x + 2) = 0, or the second factor (x + 3) = 0. The product (x + 2) (x + 3) is therefore zero if x = -2 or x = -3.

The numbers found, -2 and -3 are solutions of the equation (x + 2) (x + 3) = 0.

An equation of this type is called a “zero product equation”.

Let’s generalize :

An equation of the type (ax + b) (bx + c) = 0 is called a zero product equation.

The solutions of such an equation are the solutions of each of the equations ax + b = 0 and cx + d = 0

(See the little summary at the bottom of page 32.)
