3rd Grade Math - Rounding Numbers

Updated: Nov 12, 2023

This post explains and gives practice opportunities related to TEKS 3.2C:

represent a number on a number line as being between two consecutive multiples of 10; 100; 1,000; or 10,000 and use words to describe relative size of numbers in order to round whole numbers


This standard can get easily dumbed down to rounding numbers but, when ready completely, is much more than that. Looking at the TEKS, students should know that numbers sit between consecutive multiples of 10, 100, or 1,000 on a number line in order to round using words.

Oral Language Development

Students process information through talking and conversing, not simply listening or watching a teacher demonstration. Here are so talk structures aligned with 3.2C to help you students unmute in the classroom.

You can find the Google Slide version here. You can also learn more about the Unmute model here.


STAAR Practice

Between 2016 and 2023 (including STAAR redesign), this supporting standard has been tested 2 times on the STAAR test. Videos explaining each problem can be found below. If you'd rather take a quiz over these questions, click here. The videos below are linked to the question in the quiz as answer explanations after the quiz is submitted.
