Help your math students improve their speed and accuracy-no matter what level they're at! High achievers can challenge themselves to master speedy calculations, while low-achievers can develop an interest in working with numbers while destroying "math-phobia." This elementary-grade workbook covers addition and subtraction problems with 14 "Express Strategies." Children learn sequential mental math tips, such as working to or from bases of ten (including numbers of 100), then tackling the subtraction or addition of the other numbers; word problems are also included. Examples are clearly explained: tests include room for the time taken, scoring, answers, and a word problem. 102 non-reproducible pages, softcover. Answer key included. Grades 2-4.
