# Rounding to nearest 10

This video teaches rounding numbers to the nearest 10 using number lines. It demonstrates rounding with examples like 36, 34, 35, 26, and 12, and provides a rule for rounding when the ones place is 5 or greater. This helps students practice estimation in real-life situations. Created by Sal Khan.

• How you do this
• Or 30 dosn't round up or down, it rounds to 30, also 20 rounds to 20
• why is rounding inportant
• Rounding is important to check your work easily and quickly. For example, if I were doing 52*11, I could estimate that the answer is around 520, which would allow me to check my work. Rounding also makes learning distributive properties easier in later grades.
• Is there a certain amount of numbers that u r able to round or can u round more?
• there is no limit to numbers so there is no limit to rounding.
• a great example rounding is using 20 mostly because it can relate to 2,4,6...etc so what numbers can you round it to? you can anything before 5-, example: 21, 22, 23, 24. okie dokie now try doing the other side around example: 31, 32, 33,34. Theres way more ways but for me thats the best way... if u still don't get it i hope you figure it out!
• can u plz add some more rounding ones like rounding to the nearest 1000
• how do you Round off numbers?
• Look at the smallest place value. If the number value is 5-9, round up. If it is 0-4, round down.

If it asks you to round to the nearest five, use the same logic. 0, 1, 2 = 0; 3, 4, 5 =5
• I don't know how to do the lesson
• is anyone here in may 2019/
