Place value - Rounding to the nearest 1,000 - Presentation

In an engaging presentation on rounding numbers, students in Year 6 are introduced to the concept of rounding four-digit numbers to the nearest 1,000. The lesson starts with a review of rounding rules for the nearest 10 and 100 to refresh students' memories. Following this, the class dives into the day's key topic with a series of interactive activities. The first activity involves using a number line to determine whether various numbers are closer to 4,000 or 5,000, then rounding numbers such as 4,308, 4,622, and 4,905 to the nearest 1,000. The emphasis is on understanding which place value column to consider when rounding to the nearest 1,000, a crucial step in mastering place value.

Further activities build on this foundation, with students rounding different numbers, including written and numerical representations, to the nearest 1,000. For example, they round 'Nine thousand and thirty-eight' and a number represented as 3 thousands, 3 hundreds, 3 tens, and 3 ones. The presentation also includes a reasoning section where students must decide if cars with certain mileages are advertised correctly when rounded to the nearest 1,000. Additionally, they are challenged with reasoning tasks that ask them to find possible original numbers that, when rounded, would yield 5,000, identifying the greatest and smallest numbers possible. Independent work rounds off the lesson, encouraging students to apply their rounding skills and explain their reasoning, further reinforcing their understanding of place value.
