Students will be working with a partner to generate benchmark numbers (to the nearest ten, hundred, or thousand) for number cards. They will use the benchmarks to round the number using place value understanding. The students will be standing at the front of the class to create an embodied number line using teacher and peer support.
This activity is a sorting game where students have to match multi-digit numbers to the appropriately rounded number. Students must be able to round multi-digit numbers to the nearest ten, hundred, or thousand. There is a recording sheet to track student progress.
This learning activity is a task presented to the class to introduce the topic of rounding. The real-world context of the problem engages students as they learn the purpose and strategies for rounding multi-digit whole numbers using place value understanding. Students use a number line to identify benchmark numbers.
Half-Court Rounding is a game in which students try to score as many points as possible by rounding numbers to the nearest ten, hundred, or tenth. Students can try any kind of shot within the game and have 90 seconds to score as many points as possible and beat their opponent. If they answer incorrectly, the student misses the shot. Students can also choose a two-player game where they can play a friend or classmate.
This activity results from the ALEX Resource Gap Project.
Discover how rounding off numbers helps you estimate faster. Round the numbers and make an estimation about their totals in this interactive Cyberchase activity.
In this interactive activity, students will be led through steps to estimate numbers by rounding in order to make problems easier to solve. There are teaching activities as well as practice activities available. A handout that reviews the strategies taught during the activity can be printed. After utilizing this resource, the students can complete the short quiz to assess their understanding.
