Math Practical Problems we meet in real life. The slides are an extract from free ebook A+ Click Everyday Math that helps students become problem solvers. This e-book features a collection of 120 challenging math problems. Students aged 12 years and up with an itch for math will enjoy it as much as curious adults. The e-book presents the best practical problems from www.aplusclick.com adapted to the e-book format. The website offers over 3500 problems, starting from the very simple and moving toward the extremely difficult. Each problem must be solved within one minute and without using a calculator. The exercises focus on understanding, spatial reasoning, and problem solving rather than math rules and theorems.
