Rounding to the Nearest 10: Key Strategies and Techniques

In this video, Miss B introduces the concept of rounding numbers to the nearest ten. She presents two methods: using a rhyme and a number line. The rhyme helps determine whether to round up or down based on the digit next to the rounding place. Miss B demonstrates these methods with examples, rounding the numbers 38 and 54. The video concludes with a preview of the next lesson on rounding to the nearest hundred.
