Math Man: Estimate Differences by Rounding
http://www.sheppards...
Students will round each number to the nearest 100 place and then subtract to find the difference in this pac-man like interactive game. For example: The difference of 410 - 115 is about 300. To estimate the difference of 410-115 follow these steps: 1. round the first number of 410 to 400 2. round the second number of 115 to 100 3. subtract the rounded numbers 400 - 100 = 300.

Subject: Mathematics
Title: Communicating about Mathematics Using Games: Playing Fraction Tracks
Description: Mathematical games can foster mathematical communication as students explain and justify their moves to one another. In addition, games can motivate students and engage them in thinking about and applying concepts and skills. This e-example from Illuminations contains an interactive version of a game that can be used in the grades 3-5 classroom to support students' learning about fractions. e-Math Investigations are selected e-examples from the electronic version of the Principles and Standards of School Mathematics (PSSM). The e-examples are part of the electronic version of the PSSM document. Given their interactive nature and focused discussion tied to the PSSM document, the e-examples are natural companions to the i-Math investigations.
