Dare to dream and when you do, dream big

The theory of self-fulfilled prophecy says that when we have a firm belief about ourselves, it ends up being fulfilled.

This was said by Henry Ford many years ago, in a phrase that is famous, that in a nutshell explains the reason behind the triumph or failure of many people:

“Whether you think you can, or if you think you can not, in both cases you’re right” …

This holds a very great truth, psychologists have proven it with multiple experiments and call it the theory of self-fulfilled prophecy.

If a student believes that they are bad at their studies, they do not put their commitment into school, they frequently fail, lower their self-esteem, conform to low grades, do not participate in class, do not ask questions because they think they will not understand. They are assigned the label of mediocre, playful, or chatterbox and soon will be seen as such by their classmates and their teachers. The child tends to behave according to the expectation they have of him. (The Rosenthal and Jacobson experiment in 1966 is well known) and is known as the Pygmalion effect or self-fulfilling prophecy.

All of us who have been teachers for a long time have seen how important a student’s self-motivation is for their success in school and life. Behind winning students, there are usually parents, grandparents and family members who believed in them and encouraged them to persevere when they had a problem. How often teachers make the big mistake of highlighting faults and ignoring the qualities and effort of our students.

Similarly, many times parents are responsible for the low self-esteem of their children. If they say to him every day; you are a loser, you are useless at everything, you are not like your older brother who is intelligent and responsible or some other derogatory phrase, and they only see the defects and do not publicly acknowledge his qualities, they are condemning this son to failure in life.

The emotional support that parents and teachers give their children is very important.

If you want to succeed in life commit yourself to do so, take advantage of this great opportunity you have at this time to study and show the world how much you are worth, the great potential you have to face any challenge and overcome it.

If you do not stop yourself, no one else can do it. Dare to succeed.

Do you really want to succeed in life?

If you really want to succeed, the secret is simple: study. If you compare what a worker who just finished High School (which is the basic level they ask for any job) earns, against what someone who has finished a professional career, a master’s degree or a doctorate, the difference really is enormous.

A person who just finished High School has an income that is just at the poverty line. Instead, a professional has the money to live comfortably and fully enjoy their family. Good homes, good cars, good medical care, holidays and all the comforts of modern life. It is estimated that with only four additional years of study the difference in income over 30 years of work is more than one million dollars.

Let’s do some quick accounting; a minimum wage person earns $ 7.25 an hour ($ 58 a day) when he gets a job. If you are sick with the flu and your mom takes you to the general practitioner for a 15-minute consultation, the fee is $ 50, so they can earn $ 200 in one hour (on a good day $ 1,600 or more). In two weeks a professional can earn what a minimum wage employee earns in a year. In addition, the physical effort is very different; it is not the same to be working where every day you are moving heavy things and doing strenuous work, compared to the physical effort of a professional, which in most professions is minimal because it is intellectual work.

Have confidence in yourself, you must believe in yourself; do not ever get defeated. Dare to dream. If you have a dream, pursue it. Set goals and have the courage, determination, and dedication to achieve them. In life, you will always find obstacles and pitfalls, but you must have the will to rise and persevere. Only the one who gives up is defeated.

If you want to be part of a success story – study. Many students do not finish high school because they did not arrive well prepared in their subjects from the previous years. In Middle School, you learn the bases that will allow you to succeed later in your studies. All construction requires a good foundation, and here we are laying the foundations of what you will build tomorrow.

At Middle School, you must create solid foundations in reading, writing, and mathematics. I do not worry about how low your math skills are; I offer you that if you attend class regularly, if you pay attention, if you do the assigned activities and you frankly consult your doubts in order to clarify them, you will learn what is necessary to get ahead in your studies. I have 30 years as a teacher, and many of my alumni are successful; Even former students, some who had never passed a Texas state test, have achieved Commended Performance and then have achieved a professional career.

Success depends on the will rather than the talent. The foundations of your future and that of your family are built today. Dare to succeed.

Similarity.  Measurement Application with Ratios 


  • Similar figures are the same shape but can be different sizes.
  • The scale factor between similar figures is the factor by which the figure is reduced or enlarged.
  • Corresponding sides of similar figures are proportional.
  • There are different ways to express probability numerically: as a ratio, a decimal, and a percentage.

If the scale factor is greater than 1, the dilation is an enlargement.

If the scale factor is less than 1, it’s a reduction.

  • Understand the concept of a unit rate.
  • Identify the constant of proportionality (unit rate) in tables, graphs, equations, diagrams, and verbal descriptions of proportional relationships.
  • Solve unit rate problems (including those involving unit pricing and constant speed).
  • Use ratio and rate reasoning to solve real-world and mathematical problems,
  • Use ratio reasoning to convert measurement units.
  • Developing an understanding of slope.
  • Recognize and represent proportional relationships between quantities.
  • Represent proportional relationships by equations.
  • Decide whether two quantities are in a proportional relationship.
  • Graphs and two-variable equations.
  • Find a percent of a quantity as a rate per 100.

  • Use proportional relationships to solve multistep ratio and percent problems.

Please write and solve your own real-life word problem about one of the topics corresponding to Proportionality.

It is very important that the teacher knows the strengths and weaknesses of their students to help them to be successful academically. This CBA2 assessment is just one of the ways to collect data to meet LISD goals.

If you have doubts about one or several of these topics, please let me know to solve them immediately.

Weekly Math Assignments.

It is very important that you review all the mistakes you made in the CBA2 (CBA2 Make-Up). The assessment was about Ratios, Rates, Proportional Relationships. and Percents. As soon as I return to class, I will clarify all the doubts that you may have. Meanwhile, you can review the main concepts in the corresponding blog posts. If you have problems to do it at school, please do these assignments as a homework, and I will give you extra points to do so.

This week should cover Inversely Proportional Relationships. And you can also review some topics that we have already covered like Areas (circle, square, triangle, rectangle, and trapezoid), surface areas (cube, rectangular prism, and triangular prisms), and composite figures.
