Spanish Verbs Find topics in left sidebar in top menu.Anyone who has studied Spanish knows that one of the biggest challenges is to learn all of the verb conjugations. That’s why we created this section. Spanish Verb Quizzes Exponents Calculator Example entries -42 or (-4)2 will result in different answers. Note that -42 = -1 * 4 * 4 = -16 while (-4)2 = (-4) * (-4) = 16. See notes below. This is an online calculator with exponents. "When a minus sign occurs with exponential notation, a certain caution is in order. For example, (-4)2 means that -4 is to be raised to the second power. Interactive angles - Middle/High This activity allows manipulation and investigation of various types of angles. It can be used at a variety of different grade levels. At its most basic for teaching about types of angles, acute, obtuse or reflex. For more advanced use to create angle problems in which the missing letter angle values have to be found. You can click and drag the handles to change the angles and the values will updated.
Exponents The exponent of a number says how many times to use the number in a multiplication. In 82 the "2" says to use 8 twice in a multiplication, so 82 = 8 × 8 = 64 In words: 82 could be called "8 to the power 2" or "8 to the second power", or simply "8 squared" Exponents are also called Powers or Indices. The Secret to Finding ‘Aha’ Moments in Math Class After several decades of experimentation with technology in schools, we continue to face fundamental questions: What role should technology have in the classroom? How often should it be used? What are the opportunities for technology to transform both teaching and learning? As the CEO of Woot Math and previously of Kerpoof, I have spent the last ten years grappling with questions like these. Of course the answers are not easy or obvious, but I think asking these type of questions is critical in mapping a path towards innovation.

They aren't all open source, but they are all extremely useful, and they are all free to use (free as in free beer, some of them are also free as in free speech). Geogebra This program lets you explore algebra and geometry, much like it's proprietary cousin, Geometer's Sketchpad.
