Friendly numbers are multiples of 10 that make it easy to add or subtract. They help us estimate when we don't need an exact answer. In this lesson, students will learn about friendly numbers and how they can simplify calculations.

Rounding off using a number line involves locating the given number on the number line and identifying the nearest ten. Students will understand the concept of rounding down and rounding up based on the position of the number on the number line.

Certainly! To round off two-digit numbers, students will look at the digit in the ones place. If it is less than 5, they round down to the nearest ten. If it is 5 or greater, they round up to the nearest ten.
