Rounding and Estimating Numbers

I use this in my class with those students who aren't quite getting how to round yet.  They either sit with me or a para pro and discuss these questions.

This is a simple number line make that allows teachers to generate custom number lines  Below are some examples of number lines that can be created.

Teachers can create arrays and visually show how division works.  Using the program students can also work on estimation, factoring, remainders, and fractions that all deal with division.  Factor Pairs and Prime factors can also be shown.  Teachers can use this to show why some numbers are perfect squares and some are perfect triangles.  Watch the video to show how to change and use this number explorer with students.

Students will review rounding to the nearest 10s, 100s, and 1000s in this math worksheet.

A third-grade worksheet designed to reinforce rounding numbers to the nearest 10 and nearest 100.  It included 3 word problems, 4 questions using a number line, and a mix of rounding to 10s and 100s.

Students will practice rounding numbers to the nearest 10.  Two number lines are included for reference as well as two elapsed time problems for students to practice.

Students will practice rounding to the nearest 100.  There are number lines to give a visual if they need them.  Also, there are two elapsed time review questions.
