Rotations, Reflections, Angles and Directions

Rationale- This unit is part of the geometry unit. Students use their knowledge of angles, rotation and importance of following set directions to solve problems.

Tasks-

-4Mat Symmetry Lesson

-Students will write in journals about rotation, reflection, angles and following directions

-Students will work on 3 tasks on the computer. The first is using Math Rock CD. The students will try to get a skater to and from a specific place. The students use specific directions to get the skater to the proper place. The second uses a program called The Factory. The students must reproduce a specific design using a combination of specific machines. One machine rotates the design, one punches holes in the design, and one makes lines on the design. The third uses ClarisDraw to create shapes, rotate and reverse them. For all activities the students will follow teacher created directions.

-Students will do activities from the book Spatial Problem Solving

Assessments

-4Mat lesson's final project is either correct or not. Pass/Fail

-Teacher assess journal entries with a rubric.

-Computer activities have worksheets that are completed as students do the activities. Teacher checks understanding as students use the computers and by checking the worksheets.

-Teacher monitors Spatial Problem Solving activities as students complete the activities.
