TI-15 Math Explorer Calculator
“From the kitchen table to the playground, children are intrigued by their world. The TI-15 Explorer™ is apedagogically sound tool that helps students make connections between classroom learning and real-world situations. The TI-15 Explorer combines the fraction capabilities of the Math Explorer™ with a two-line display, problem solving, place value and more. When the TI-15 Explorer™ is combined with traditional learning tools, it helps students explore their world through investigation and experimentation, and helps develop skills in addition, subtraction, powers, and answer format.”
