Also, the long summer break can have a greater negative effect on the learning of children with special educational needs.
How does summer vacation affect student achievement?
The authors concluded that: (1) on average, students’ achievement scores declined over summer vacation by one month’s worth of school-year learning, (2) declines were sharper for math than for reading, and (3) the extent of loss was larger at higher grade levels.
Does summer break benefit students?
Relaxing during summer break is important because it allows students to recharge for the fall quarter. After a stressful year of nonstop work, students who choose not to take the summer off will find themselves burnt out and less motivated during the regular academic year.

Why 1 is not a prime number?
The confusion begins with this definition a person might give of “prime”: a prime number is a positive whole number that is only divisible by 1 and itself. The number 1 is divisible by 1, and it’s divisible by itself. But itself and 1 are not two distinct factors. Excluding 1 from the primes smooths that out.

How useful is zero in our life?
It plays a central role in mathematics as the identity element of integer, real number, and many other algebraic structures. As a digit, zero is used as a placeholder in the location value system. As a digit, zero is used as a placeholder in the location value system. Historically, this was the last point in use.
Why does zero exist?
Zero exists because all the numbers with 0 in it, like 10, would be just 1. Zero exists because if it didn’t, you will say nothing instead of zero. And 10, 20, 30, 40, 50, 60, 70, 80, 90 and 100 would not exist!

What would happen if there were no numbers?
If we don’t have numbers, we lack the ability to describe a great many things with precision, quantitatively. It is exactly that ability that gives us such power over our environment, so (from the outside) without it, we would appear just as powerless as any other species. (Or at least, nearly so.)
What would life be like if you didn’t have numbers?

What will happen to the world of mathematics does not exist?
Maths has to exist because the universe is goverened by it, if our understanding of maths didn’t exist then nothing would really happen, we would be very limited in terms of technological advancement.
