Introduction to Geometry • Picture things in your mind • Draw them with your hand and with computer tools • Describe pictures and drawings with appropriate language • This is a good start to the year
Habits of Minds • Visualizing • Experimenting • Describing with formal and informal language • Making and using definitions • Students develop skills with computer tools
8 1 2 3 6 7 4 5 • Can the shadow of a square on a flat floor or wall ever be non-square? Can it ever be non-rectangular? • Which of these shadows could be cast by a square and which could not? • What kinds of shadows will an equilateral triangle cast?
Connected Geometry • The goal of a math teacher is to make mathematics compelling and attractive to students. • All mathematics is fair game for connected geometry. • Encourage students not only to learn math content,but also to use and value math habits of mind.
Connected Geometry • Students first explore open ended problems. • Students refine these processes into formal algorithms. • Students learn about concept of area, area formulas and the Pythagorean Theorem. • Any triangle may be cut into a rectangle.
Spreadsheets and Graphs Spreadsheets are a good way to reinforce math concepts. Graphs introduce relationships among decimals, fractions and percentages.
Mean and Formula • Introduce concepts of mean and using formula. • Don’t teach students shortcuts to the computer commands first. • Students need to understand formulas.
Prepare Students for Testing • Use power point to show students what they need to do to prepare themselves for testing • How and when to use mental math problem solving • How to use the vocabulary of mathematics in their written solutions. • How to read open-ended tasks, select necessary information, devise a method of solution, perform appropriate calculations, and explain in writing the procedure used.
How teachers can help students perform successfully • Familiarize themselves with students’ results. • Analyze those results to determine a pattern of strengths and weaknesses. • Identify strategies to help students improve their performance. • Translate those strategies into instructional and practices.
How teachers can help students perform successfully • Show logical and mathematical evidence as a verification for right answers • Mathematical reasoning and memorization procedures. • Connecting mathematics, its ideas, and its applications and away from treating mathematics as isolated concepts and procedures.
Using technology in cooperative learning • Students engage in cooperative learning • Work as a group to solve problems • The website I suggested to students is Word Problem for kids : http://www.mathstories.com • The stairway is made of cubes. How many cubes would be needed to make h? 1) Look for a pattern Steps Cubes Sum (Top -> Bottom) 2 3 1 + 2 3 6 1 + 2 + 3 Find a pattern.
Making Math Fun • The following website is a unit designed for elementary students. http://www.math.nmsu.edu/breakingaway/Lessons/polygonanimal/cutout1.html • This unit emphasizes skills in drawing equilateral triangles, squares, and regular pentagons and hexagons. • It also involves precision cutting, and putting together geometric shapes to form "puzzles" that look like stylized animals or other objects.
Making a fox from a triangle Using compass and ruler, draw an equilateral triangle approximately three inches on a side, using the two-colored posterboard. Before cutting it out, set your compass radius at one half the length of a side. Put the point of the compass on a vertex of the triangle, and swing an arc of 60 degrees. Move the compass to another vertex, and draw a second arc of 60 degrees. You should have a shape like this:
Making a fox from a triangle cont. Carefully cut out the triangle, and cut along the arcs to make three pieces. Reverse the two part circles, and you have a stylized fox
Making a fish from a square Using compass and ruler, or protractor or index card, draw a square approximately three inches on a side, using the two-colored posterboard. Before cutting it out, set your compass radius at one half the length of a side. Put the point of the compass on three different vertices of the square, and swing three arcs of 90 degrees. You should have a shape like this:
Making a fish from a square cont. Carefully cut out the square and cut along the arcs, getting four pieces. Reassemble them to look like a fish:
