Subject: Re: Lego blocks as problem solving tool
I am guessing you must have a large quantity of these blocks. What a great idea to try to use them for a bit more than just building. What about fraction concepts? If you have some that are the square shape and others that are rectangular, you could use them to demonstrate halves and wholes. They could be used to build bar graphs as students collected data. They could be used in patterning: one block in the first tower, 3 in the next, 5 in the next, 7 in the next. or 2 in the first, 4 in the next, then 6 then 8 or 1 in the first, 2 in the next, 4 in the next, 7 in the next, 11 in the next. Here are some sites you may want to try for more ideas. http://www.ee.ryerson.ca/~elf/abacus/ Build a LEGO abacus · Books about the abacus · Math and science resources for teachers · Java applet source code · Other abacus links http://www.tabletoptelephone.com/~hopspage/Cubes.html Yamamoto's blocks are superior to Legos http://www.blake.pvt.k12.mn.us/campus/projects/lower/lego/ Lower School LEGO Projects http://www.iit.edu/~smile/ma9530.html Objectives (Grades 3-5): To learn two-digit multiplication using math facts. To find areas of rectangles and squares. To review addition and subtraction facts. To be able to fill an order of items of equal and different prices and quantities. Materials Needed: rulers, stamps (new and/or used, singles and sheets of different denominations and sizes), magazine ads stamps (from the Ed McMahon $10,000,000 Sweepstakes), stamp order catalogues, play money (dollars and change), transparent grids and Lego platforms with different numbers of squares and dots, scissors, and order forms -Gail, for the Teacher2Teacher service
