Subtraction Worksheets submitted by: Jeff LeMieux, August, 2003 This narrative describes how I use my javascript tool, cataloged in the Math Tools digital library, in the classroom. Course: Math 7 Topic: Operations with Numbers - Subtraction Resource type: JavaScript Resource location: http://www2.whidbey.net/ohmsmath/webwork/javascript/subwrk.html Math Forum catalogue entry: http://mathforum.org/mathtools/tool.html?rc=tool&new_id=1578 Story:  Subtraction, especially subtraction with borrowing and subtraction with borrowing from zero place-holders is one of the skill areas which needs review and periodic refreshment. It is not unusual to have a middle level student who may require additional instruction in this area. While these sheets do not provide instruction, they are a vehicle for demonstraction, review and practice. The format (positive integer subtraction) allows a degree of control to determine the length of minuends (5 digits) and subtrahends (5 digits) and the number of problems (30 max). Answers are provided but must be copied and/or saved. Please note that specifying a length means the number will contain that many digits as a maximum. There might be fewer. Where and how I used this: Typically, this is used as a group review. An overhead master is printed from the web page and students direct the solution to the problems. They are handy for individual cases of remediation. They can be used to practice estimation.
