It is amazing the difference in effort you will get from worksheet to worksheet. Granted the amount of effort may vary immensely from year to year depending on the group of students you have. However for the most part, when a worksheet is needed to help drill down a procedure, standard, or lesson, its effectiveness can and will vary. Therefore it is our job as the teacher to make sure that when we need to utilize a worksheet, we provide the students with one that is as inspiring as can be. Times are different these days. Kids are growing up in a world of microwaves, fast food chains, Nintendo, Wifi, iPads, along with a ton of other technical marvels. When I was growing up we didn't have home computers let alone PlayStation to entertain ourselves. Handheld camcorders were barely coming to the retail market by the time I was in 8th grade, but still a long ways away from the YouTube and Facebook arena we now see today. Times were extremely different back then and so was school.
Math worksheets don't promote communication and collaboration _ Math worksheets are often assigned as an independent activity, however research indicates that communication and discourse are needed to build a deep understanding of math topics. Students need opportunities to explore mathematical ideas in different ways and to build their own connections. This involves communicating their ideas, listening to the ideas of others, arguing a viewpoint, describing, and explaining. Math worksheets are rarely used as a catalyst for conversation. Instead of assigning worksheets, find activities that encourage discourse, such as "number talks," or collaborative group work. During the session, be sure to require students to explain their thinking and listen to the strategies and thinking of their peers. If you are fortunate enough to have an interactive whiteboard in your classroom, using it with interactive math software creates many opportunities for group discussion and student participation. Teachers can can begin by posing problems and modeling approaches, and then ask students to work together to find solutions. Then have them come to the board to demonstrate their solutions in front of the class. These days, many examples of how to teach math concepts on an interactive whiteboard can be found online in the various whiteboard community sites, educational sites, YouTube, etc.
