This exciting text for the pre-service elementary teacher provides hands on mathematics lessons they can use to introduce mathematical concepts and skills that students find particularly challenging. Each chapter is divided into four sections: *The Activity employs an engaging thought experiment to help the reader visit a classroom to understand how the lesson used to introduce the concept or skill would materialize in the class. *The Mathematics provides the necessary mathematical background used in the lesson to make the actual teaching/learning situation comfortable for both the teachers and the learner. *The Plan provides the reader with an actual lesson plan to engage the Activity in the classroom setting. *Putting It All Together pulls the previous sections together with a summary of the chapter as well as further information for making the lesson successful. By providing models of what excellent lessons on a given topic look like, knowledge of the mathematics involved, and a concrete lesson plan structure this much-needed resource is the definitive mathematics planning vehicle that every teacher will want before they set foot in their own elementary classroom.
