Rounding numbers makes math friendlier by swapping big numbers for simpler ones. This lesson uses clear examples and spoken hints to guide each step.

When you round 347 you check the tens digit. It shows four so you drop the last two digits to get 300.

With 856 you spot the tens digit and find a five or higher. That pushes the hundreds place up by one and turns the number into 900.
