Rounding to the Nearest 10 (Part 1)

The video tutorial explains the concept of rounding numbers to make calculations easier. It focuses on rounding numbers to the nearest 10, using examples to illustrate the process. The tutorial covers identifying benchmark numbers, understanding midpoints, and deciding which benchmark is closest to the given number. The example of rounding the number 13 is used to demonstrate these concepts, highlighting the steps involved in rounding down when necessary.

What is the main advantage of rounding numbers?

• It makes numbers more complex.

• It simplifies calculations.

• It increases the number of digits.

• It makes numbers harder to understand.

What are tens values?

• Numbers that are prime.

• Numbers that end with 5.

• Any random numbers.

• Two-digit numbers that end with 0.

What are benchmark numbers?

• Numbers that are always even.

• Numbers that are closest tens values to a given number.

• Numbers that are always odd.

• Numbers that are multiples of 3.

How do you identify the midpoint between two benchmark numbers?

• It is the larger of the two benchmarks.

• It is the number that is equidistant from both benchmarks.

• It is the smaller of the two benchmarks.

• It is always the number 10.

What does it mean to round down a number?

• To increase the number to the next tens value.

• To convert the number to a fraction.

• To keep the number unchanged.

• To decrease the number to the nearest lower tens value.
