Original Promptunit on rounding the nearest 10s place value
This resource focuses on rounding two-digit and three-digit numbers to the nearest ten, helping students understand the concept through number lines and place value reasoning. It begins with the guiding principle that the digit in the ones place determines whether to round up or down. If the ones digit is between 0 and 4, students round down to the nearest ten, while digits from 5 to 9 prompt rounding up. The resource includes multiple examples, guided practice to reinforce understanding, independent practice exercises, and a final challenge that encourages students to articulate their rounding strategies. This comprehensive approach ensures mastery of the rounding concept through both guided and independent activities.
