Stop The Summer Slide!


Summer vacation is around the corner and with summer comes the threat of the dreaded summer slide.  After an entire school year of hard work your child is at risk for losing an average of two months of academic skills.

The good news is that the summer slide can be prevented with summer learning. Do not fret, tackling summer learning does not have to be complicated. Creating a summer learning plan can be simple and begins by determining your child’s needs. Below are questions to consider regarding your child and ways to support their summer learning.

Did your child struggle with a specific subject this school year?

  • Focus on that subject by relearning concepts your child struggled with.
  • Consider hiring an expert tutor in that specific subject.

Is your child anxious about transitioning to a new grade or new school?

  • Spend time introducing new concepts during the summer to help your child feel more confident in their transition.

Your child had an amazing school year and you would hate for their learning spree to end during the summer?

  • Encourage summer learning by challenging your child with new learning opportunities!

Happy summer learning!

What are Functions?


Functions are an important concept and are therefore, heavily tested on the new SAT. It is important to become proficient with them. But, what is a function anyway? In mathematics, a function relates to an output that resulted from an input. It is like in computer science when you learn about input and output devices and the relationship between both. For example, you put in an input into the computer in the form of instructions, and it resulted in an output in the form of a printed document. In the real world context, other ways in which the concept of functions occurs it in factories where you have large machinery. The machines work in the same context of input and output.

A function is usually denoted by “f(x) =…” , the f, is not unique and any letter can be used.

A function has three main parts:

  1. The input
  2. The relationship
  3. The output

Example: “Multiply by 4” is a very simple function you can grasp.

Input = 5, Relationship = × 4, Output = 20.

Consider this: For an input at 40 what is the output?

Examples of functions

f(x) = x2 + 3

g(x) = 2x – 7

The above definition of a function is considered as the basic understandable definition. It goes deeper. A function may also be considered as a relation that uniquely maps one member of a domain unto another member of a range which is a subset of a codomain. This means, if you have a function which maps set A to B, it is an object f such that   is mapped onto one or more members of the range such that. The range is part of a codomain. This means that a function can be a many to one or one to one relation. If you have a one to many relation that is not a function. Let us look at range, domain and codomain to get a better understanding of the aforementioned definition. But first let us look at one to one and one to many mapping.

Understanding the difference between the range and the codomain is very critical. It even becomes more critical when doing further math such as pre-calculus where a function is undefined.

Example 1

What is the domain and range of the function: f(x) = 2x2 + 6?

To answer this question, you need to think about all the possible values than can be inputted into the function and get an output. By looking at the function you realize than any real number can be placed into the function to produce an output. Also, you may also realize that the set of integers can also be used. If you use any random integer for example -3, you can check

Thus f(-3) = 2(-3)2 + 6

= 2(9) + 6

= 18 + 6

= 22

You may also notice that all the output for the set of real numbers will be the same for the set of integers because of the x2. Therefore the domain is the set of integers. Since the set of real numbers is a subset of the set of integers, we can exclude it. Note that the domain does not have one set definition, because it could also be the set of counting number, whole numbers, etc. However for the range, you will never get a negative output, so the range could never be the set of integers, but it could possibly be the set of even numbers, however the range is the set {8, 14, 22…}. Though the question didn’t ask, but the codomain could be the set of counting numbers, since the output could be any possible counting number.

Evaluating Functions

Evaluating functions is quite simple, all you need to do, if plug in the value that is given, substitute the value for I, then solve the equation.

Example 2

Function f is defined by
f(x) = – 2x2 + 6x – 3, find f(- 2).

What you do in this instance, you substitute -2 for ‘x’ in the function then solve

= -2(-2)2 + 6(-2) – 3

= -2(4) – 12 – 3

= -4 – 12 – 3

= – 19

Example 3

Two functions f and g is defined by

f(x) = 2x + 7 and g(x) = -5x – 3, find (f + g)(x).

When you look at the question it might seem hard, but it is quite simple. You may note that (f + g)(x) denotes is the product of two numbers ideally. It can be expanded as such

(f + g)(x) = f(x) + g(x). As such, this is in a form that we can understand therefore it is:

f(x) + g(x) = (2x + 7) + (-5x – 3). Note: the brackets are there to show the two distinct functions

2x + 7 – 5x – 3 by grouping like terms”

2x – 5x + 7 – 3

= – 3x + 4

Therefore (f + g)(x) = – 3x + 4

Example 4

Two functions f and g is defined by

f(x) = 2x2 – 3x and g(x) = x + 1, find f (g)(-3).

What you see above is called a function of a function. It is quite easier than it looks. What is means that wherever you see x in function f, you are going to plug put the g function then plug in -3. Therefore:

f (g)(x) = 2(x + 1)2 – 3(x + 1). Thus, we first put the g function in the f function. Now we evaluate for:

f (g)(-3) = 2(-3 + 1)2 – 3(-3 + 1)

= 2(-2)2 – 3(-2)

= 2(4) + 6

= 8 + 6

= 14

Therefore f (g)(-3) = 14

If we were not asked to evaluate f (g)(-3), but just find f (g)(x)

The answer would just be: 2(x + 1)2 – 3(x + 1).

You may also note that a function can be graphed and in that context, the x is the domain and y is the range so sometimes you will see that f(x) = y.

Range, Domain and Codomain

The first diagram represents a one to one mapping, where each element of X maps exactly onto one Element of Y. The second diagram represents aone to many mapping where one element of X maps onto one of more element of Y.

A domain is simply all the possible values that can be inputted into a function to produce an output.

The range is simply all the output of a function.

The codomain is all the possible outcomes or output from a function.

How to Make Sure Your Child Sticks to Good Habits This Summer


For kids, summer is a time to slack off, goof off, and generally forget they have any sort of responsibilities whatsoever. And yes, while there is room for some of this, it’s the job of parents to make sure their children stick to good habits during the free-for-all that is summer break. Without some sort of schedule, kids can waste valuable time, fall behind in their education, and develop risky behaviors. Here’s how you can make sure your child maintains safe, productive habits.


Schedule time to learn/improve at a hobby


Instead of just setting a strict summer schedule for the sake of fitting in time to read, do chores, and setting consistent sleep patterns (all of which are important), use a summer schedule to build in time for self-improvement. Learn or get better at a task or hobby.


“If you love doing something enough, you should find time to do it. It will make you happier and healthier, which means you’re bound to do better in school and everything else as well,” notes “Set aside a time every few days or every week, for instance, to pursue your newly found hobby. By working it into your schedule, it won’t feel like something you can do without,”


Setting goals for the summer is a great way to make sure kids stay occupied in a productive manner. One or two summer’s end goals is probably enough – you don’t want to overdo it and spread your child too thin. Summer still needs to feel like summer.


Prevent education stagnation


Though you want a good part of the summer to be about outdoor activities, sports, games, pool time, and just lounging around, you would be doing your child a disservice not to schedule in some sort of educational activity almost every day. Whether your kid needs help on a specific school subject they’re struggling with, or you simply want to give them a kickstart for the next school year, there are plenty of ways to fit education into the summer schedule – and a lot of it can even be fun.


  • Schedule reading hours every day. This one is a no-brainer. Have you child sit down and read a book every day of the summer. Coordinate with their school to see if they can get a head start on any of the upcoming year’s reading materials.
  • Take educational trips. In most cities/towns in the US you’re never too far away from some sort of museum, national landmark, or historical site of significance. Schedule day trips and even longer vacations with education in mind.
  • Get your child involved in summer meals. “Cooking is a great way to teach about measurements and how to use fractions. Theme nights for dinner not only teach cooking skills, but math, as you teach your child how to measure and convert weights, volumes and numbers,” notes The Huffington Post.


Talk to your child about the dangers of substances


Summer, with all its free time, increases the chances of your child experimenting with or falling into patterns of risky behavior. You must keep an open communication line when it comes to drugs and alcohol. Your kid needs to know that they can be honest with you without fear of unjust punishment, yelling, or any other general overreaction. Use books, TV, and movies as segways into frank discussions.


“Take advantage of ‘teachable moments’. If you see a character in a movie or on TV with a cigarette, talk about smoking, nicotine addiction, and what smoking does to a person’s body. This can lead into a discussion about other drugs and how they could cause harm,” says one good suggestion.
If you want to make sure your child sticks to good habits this summer, you need to set a schedule, occupy their time, and focus on fun sources of education and other out-of-the-box learning experiences. On top of that, you need to be frank about the dangers of substances, which can increase as your child spends more free time with friends during the summer months.
