4434Statistics in Schools
https://www.merlot.org/merlot/viewMaterial.htm?id=1230631
The U.S. Census Bureau Statistics in Schools program provides resourcs for teaching and learning with real life data. The site has standards-aligned classroom-ready activities for math and history.Wed, 14 Sep 2016 09:18:45 -0700Using Statistical Analysis to Verify Conclusions
https://www.merlot.org/merlot/viewMaterial.htm?id=1212746
This lesson uses data from the Center for Disease Control to give students experience with the Chi-Square Statistic. Students will use spreadsheets to organize data, which they will then perform statistical analysis on. In the end they will determine whether there is an association between specified variables using the Chi-Square Statistic. Student materials are available for download here (second row, second column of table).Wed, 3 Aug 2016 13:59:56 -0700Transformations and Frieze Patterns
https://www.merlot.org/merlot/viewMaterial.htm?id=1212737
This geometry unit from Illuminations will help students learning about symmetry and rotation in figures and patterns. Using decorative figures and patterns, students will learn to recognize and classify symmetry. Students should have some basic knowledge of the fundamental transformations (translation, rotation and reflection- horizontal and vertical). The unit includes two lessons, each of which should require 1 class period to complete. The material is intended for grades 9-12.Wed, 3 Aug 2016 13:59:49 -0700Perplexing Parallelograms
https://www.merlot.org/merlot/viewMaterial.htm?id=1212735
This geometry lesson from Illuminations asks students to draw two line segments through a point on the diagonal of a parallelogram and parallel to the sides. Students will examine a geometric shape, analyze the patterns of the shape, and create conjectures, which they will then try to prove or disprove. The material is appropriate for grades 9-12 and should require 1 class period to complete.Wed, 3 Aug 2016 13:59:46 -0700Stacking Squares
https://www.merlot.org/merlot/viewMaterial.htm?id=1212733
This math lesson from Illuminations uses squares to represent equivalences involving square- and cube-roots. Students will be able to make and test theories of connections between geometric and numeric representations of squares and between whole numbers and their square-roots. The lesson is intended for grades 9-12 and should require 2 class periods to complete. A student activity sheet is included.Wed, 3 Aug 2016 13:59:44 -0700Triangle Classification
https://www.merlot.org/merlot/viewMaterial.htm?id=1212731
This geometry lesson from Illuminations presents the Triangle Classification problem. Students will attempt to classify the triangles formed in a plane when a randomly selected point is connected to the endpoints of a given line segment. Students should have access to a computer with internet access for the lesson. The material is intended for grades 9-12 and should require 1 class period to complete.Wed, 3 Aug 2016 13:59:42 -0700Symmetries IV
https://www.merlot.org/merlot/viewMaterial.htm?id=1212729
This geometry lesson, one in a series of lessons on symmetries from Illuminations, looks at glide reflection. Glide reflection is a symmetry transformation that is made up of two other symmetry transformations (a translation and a reflection). Graphic representations of the material are included to help students visualize the concepts. The lesson is intended for grades 9-12 and should require 1 class period to complete.Wed, 3 Aug 2016 13:59:40 -0700Symmetries III
https://www.merlot.org/merlot/viewMaterial.htm?id=1212727
This geometry lesson from Illuminations investigates translations and their properties. The material will help students understand how translations work and what happens when two or more translations are applied one after the other. The lesson is intended for grades 9-12 and should require 1 class period to complete.Wed, 3 Aug 2016 13:59:38 -0700Joking with Proofs
https://www.merlot.org/merlot/viewMaterial.htm?id=1212719
This geometry lesson from Illuminations aids students in the transition from using two-column proofs to paragraph-style proofs. The material helps students to understand proofs as chains of statements, and learn to think of proofs as presentation tools rather than an effort to find unknown values or a solution. The lesson is appropriate for grades 9-12 and should require 1 class period to complete.Wed, 3 Aug 2016 13:59:30 -0700Pieces of Proof
https://www.merlot.org/merlot/viewMaterial.htm?id=1212717
This lesson offers help to students who will eventually write mathematical proofs. The material allows students to put together statements and reasons to build a formal proof. The lesson involves identifying the properties that exist in a given figure, and apply postulates and theorems to a figure to build a formal proof. The material is appropriate for grades 9-12 and should require 1 class period to complete. Worksheets are included.Wed, 3 Aug 2016 13:59:28 -0700
