WHAT DO YOU SEE?

AND MATHBy Natalie Farthing

Standards 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.

What are illusions?

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.

What Do You See Below? This one is quite tricky!

The word TEACH reflects as LEARN

Which Direction?

Which direction is the dot moving?

(Use the math term we learned this week)

Pink/Green Dot

Count The Black Dots

Are The Lines Parallel?

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

Two Faces or One Face?

Up or Down?

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

Which is Tallest?

Which of the figures in the picture do you think would measure the tallest with a ruler?
