Analyzing With Van Hiele Levels
In this course, we have primarily worked across levels 24. You may feel that the activities weve done are not appropriate for the level of your students, and youre probably right. The goal for this session is for you to think about problems and activities that are at your students level, and how to help them prepare for the next level of thinking.
Students in preK2 generally fall at level 0 . This level describes students who reason about shapes primarily on the basis of visual considerations of the whole without explicit regard to the properties of the components . One goal of the schooling of these students is to move them to level 1 , where they can informally analyze component parts and attributes. In the primary grades, students build the foundation for understanding shapes, both two and threedimensional. They learn what shapes look like, the features that distinguish shapes from one another, and ways to describe shapes.

Lesson Background And Concepts For Teachers
The sum of the angles in any triangle is always 180°.
Types of triangles:
Pythagorean theorem was an idea discovered by Pythagoras, a Greek mathematician who lived from 569500 B.C. It is said that he discovered the special property of rightangled triangles while looking at the tiles of an Egyptian Palace. Pythagoras said, “In a rightangled triangle, the area of the square on the hypotenuse equals the sum of the squares on the other two sides.”
h is the hypotenuse
A radian is the angle made when the radius of a circle represents an arc on its perimeter.
One radian is the measure of the angle created at the center of a circle by an arc on the perimeter equal in length to the radius of the circle. Students can relate this measurment to the real world association of measuring the arc length of distance travelled on earth in the associated activity Stay in Shape. A radian is a different way to measure an angle than using degrees.
and length, L = 1 unit
then AOP = 1 radian
1 radian = 57.30 degrees
If there are 360º in a circle, then 360º / 57.3º per radian = 6.28 radians on the perimeter of a circle. Notice that number equals 2 x 3.14 radians therefore, 3.14 radians = 180º.

Index Of Classroom Challenges
Classroom Challenges are lessons that support teachers in formative assessment. There are 100 lessons in total, 20 at each grade from 6 to 8 and 40 for Career and College Readiness at High School Grades 9 and above. Some lessons are focused on developing math concepts, others on solving nonroutine problems.
The Brief Guide for teachers and administrators is recommended reading before using these lessons for the first time.
Each lesson is downloadable as an allinone PDF to print out, and a supporting PowerPoint presentation.

Developing Conceptual Understanding And Procedural Fluency
As each unit progresses, students are systematically introduced to representations, contexts, concepts, language, and notation. As their learning progresses, they make connections between different representations and strategies, consolidating their conceptual understanding, and see and understand more efficient methods of solving problems, supporting the shift toward procedural fluency. The distributed practice problems give students ongoing practice, which also supports developing procedural proficiency.

Introducing Van Hiele Levels
The National Council of Teachers of Mathematics identifies geometry as a strand in its Principles and Standards for School Mathematics. In grades preK through 12, instructional programs should enable all students to do the following:
 Analyze characteristics and properties of two and threedimensional geometric shapes and develop mathematical arguments about geometric relationships
 Specify locations and describe spatial relationships using coordinate geometry and other representational systems
 Apply transformations and use symmetry to analyze mathematical situations
 Use visualization, spatial reasoning, and geometric modeling to solve problems
In grades preK2 classrooms, students are expected to do the following:
 Recognize, name, build, draw, compare, and sort two and threedimensional shapes
 Describe attributes and parts of two and threedimensional shapes
 Investigate and predict the results of putting together and taking apart two and threedimensional shapes
 Recognize and apply slides, flips, and turns
 Recognize and create shapes that have symmetry
 Create mental images of geometric shapes using spatial memory and spatial visualization
 Recognize and represent shapes from different perspectives
For more information on the van Hiele levels and how to work with students within each level, read the articleGeometric Thinking and Geometric Concepts by John A. Van de Walle from Elementary and Middle School Mathematics.
