1. AND MATH By Natalie Farthing

2.  M4M2. Students will understand the concept of angles and how to measure them.  a. Use tools, such as a protractor or angle ruler, and other methods such as paper folding, drawing a diagonal in a square, to measure angles.  b. Understand the meaning and measure of a half rotation (180°) and a full rotation (360°).  M4G1. Students will define and identify the characteristics of geometric figures through examination and construction.  a. Examine and compare angles in order to classify and identify triangles by their angles.  b. Describe parallel and perpendicular lines in plane geometric figures.  c. Examine and classify quadrilaterals (including parallelograms, squares, rectangles, trapezoids, and rhombi) by their properties.  d. Compare and contrast the relationships among quadrilaterals.  M4P4. Students will make connections among mathematical ideas and to other disciplines.  a. Recognize and use connections among mathematical ideas.  b. Understand how mathematical ideas interconnect and build on one another to produce a coherent whole.  c. Recognize and apply mathematics in contexts outside of mathematics.

3.  Illusions trick us into perceiving something differently than it actually exists, so what we see does not correspond to physical reality.  Research scientists must be sure that the results of their work are not "illusory" in nature. They need to accurately report what "is," rather than their general "impression" of "what is." So, many times a scientist will repeat an experiment many times, or in different laboratories, to ensure that their results were valid. Science is only "good science" when anyone can repeat the experiment and get the same results.

4. This one is quite tricky! The word TEACH reflects as LEARN

5. Which direction is the dot moving? (Use the math term we learned this week) Pink/Green Dot

7. Are the horizontal lines parallel, or do they slope? Hering's Illusions

9. Is the book face-down? Or face-up?

10. Which of the figures in the picture do you think would measure the tallest with a ruler? Don't measure -- just guess! terror subterror sub

11. Frazier's Sprial

12. Which of the MIDDLE circles looks bigger, the one on the left, or the one on the right?

15. Muller-Lyer
