"Singapore Math: Place Value, Computation & Number Sense" is a six-part presentation on CD-ROM that can be used by individual teachers or an entire school. The author takes primary to upper elementary grade teachers through place value skills with each of the computational operations: addition, subtraction, multiplication, and division. She gives viewers clear instruction, plenty of examples, and reasons why Singapore Math strategies work. Her conversational, lively presentation is easy to follow. Teachers will see how to maximize their students' understanding of place value and develop their number sense so they learn to think mathematically. The presentation includes how to teach efficient computation strategies for every stage of development, strategic pictorial models like number bonds and branching, and mental math strategies that bridge the gap between arithmetic and algebra. This program includes everything teachers need to let their students in on the Singapore secret. These disks use programs based on ones from Singapore, where students score at the top on the international math tests. The disks incorporates differentiated instruction and can be used with any math program. Each disk runs 30 to 45 minutes--a total of 4 hours of instruction, plus a 96-page reproducible handout book.
