Sort into three groups - 14 statements. Does what it says on the tin really. It should encourage some discussion in class at the very least.

Decide whether these statements are Always, Sometimes or Never true. Cut out and stick.

Two versions are included - Version 1 (Worksheet) - Students determine whether each statement is "always true," "sometimes true," or "never true." They color each one accordingly and end up with a design that can be checked quickly for accuracy (but cannot be easily predicted by students). Version 2 (Sorting Activity) - Students can work alone or in pairs or small groups. Students sort the statement cards into the correct category on the sorting mat ("always true," "sometimes true," or "never true"). This works great as a learning station. You can print the cards on colored card stock and laminate them to re-use each year. Get your students thinking critically about situations concerning points, lines, planes, and angles. Statements include the following terms: congruent measure intersect adjacent perpendicular, parallel acute, obtuse, right supplement, complement vertex coplanar

All triangles and quarilaterals plus a regular polygon slide with 8 statements that students must decide whether they are always, sometimes or never true. This should create discussion. I have said that squares are a type of rectangle, and a rhombus is a type of parallelogram.
