The lesson is based on activities in the book by John Van de Walle:<BR/><BR/><B>Elementary and Middle School Mathematics: Teaching Developmentally (5th edition)</B><BR/><BR/>I highly suggest this book, as it has many good ideas for activities that target specific math concepts that students often lack when they get to high school.Dan Wekselgreenehttps://www.blogger.com/profile/08696028020767073620noreply@blogger.comtag:blogger.com,1999:blog-30226356.post-51394611458179780172007-12-17T17:48:00.000-08:002007-12-17T17:48:00.000-08:00I really like this lesson - If you don't mind, I'm...I really like this lesson - If you don't mind, I'm going to pass it on to our Algebra Lab teachers.<BR/><BR/>Thanks so much for sharing!Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-30226356.post-81549529140989169112007-12-16T22:16:00.000-08:002007-12-16T22:16:00.000-08:00I like your base-10 lesson, especially that your s...I like your base-10 lesson, especially that your students were able to convince each other that any of the pieces could represent one whole. This makes the connection between decimals and whole-number math easy to see, since any column could be the ones, or tens, or tenths. The relationships between neighboring columns is always the same, wherever we are in a number. Your lesson also makes clear the need for a decimal point---a simple job, marking the "ones", but very important.Denise in ILhttps://www.blogger.com/profile/11928843626113889088noreply@blogger.com
