Plane developments of geometric bodies (1): Nets of prisms A right prism is a polyhedron that has two congruents pararel polygonal faces (bases of the prism) and with all remaining faces are rectangles. The main interest of this page is to see how a right prism can be developed into a plane net. There is a platonic solid that is a prism, the cube.

Students use the frames to count, represent, compare, and compute with numbers in a particular range. The frames help students see quantities as equal groups of other quantities and in relation to benchmark quantities.

The Surprising Truth About Sniffer Dogs by Simon Oxenham I recently spent a full day at a major music festival observing police drugs dogs sniffing around the entrance, while their handlers bundled off festivalgoers into a nearby tent to have their internal orifices examined by policemen with latex gloves. I noticed that the Labradors followed procedure perfectly for about the first half hour of the day, sitting purposefully next to suspects. After half an hour or so, the dogs were clearly bored with their handlers' game and/or so overwhelmed by the aroma of drugs coming from all directions, that they spent the rest of the day casually sniffing festivalgoers' bottoms. I was shocked to see that the dog handlers occasionally and seemingly randomly behaved in the same way when dogs sniffed punters' bottoms, as when they had sat bolt upright next to a suspect.

The Elementary Math Maniac: A Fun Free Tool for Practicing Counting If you have ever been in a K-2 math class, you know how important counting is. I recently posted some of my favorite you tube videos for practicing counting, my favorite counting books, and have written a seven part series on estimating and counting routines that I use in my classroom. I have also written about interventions I use to help kids learn to count. Today I want to share with you a great tool to use on your computer, projector or SMART board to help your students practice many important counting skills Flip Counter Multiples and Factors In this activity, students identify multiples and factors and solve problems that involve finding highest common factors and lowest common multiples. Students will need a good recall of multiplication basic facts in order to be able to do these activities. Activity One and Game Discuss the definitions of multiples and factors (on the student book page) before your students begin this activity.
