  • Sally’s lessons follow an “I Do, We Do, You Do” format.  A math concept is introduced whole group, students then practice with a partner, and finish with independent work time.  This deliberate scaffolding keeps students from feeling defeated or frustrated! 
  • Sally’s packets also build slowly in difficulty.  We meet students where they are, regardless of level.  As students gain confidence, the problems get progressively harder.  Not all students will complete all problems and that is by design!  
  • Each packet finishes with a “Challenge Page” for anyone who needs something extra!  Multiple pages of practice are included in every packet to avoid early finishers. 

These Types of Triangles geometry worksheets are common core aligned to 4.G.2 and 5.G.3 (classifying triangles).

This was a great addition to my geometry review before state testing. We could go over a few as a class and then the students could work on the rest on their own. Thank you!

Questions & Answers

Standards

to see state-specific standards (only available in the US).
Classify two-dimensional figures based on the presence or absence of parallel or perpendicular lines, or the presence or absence of angles of a specified size. Recognize right triangles as a category, and identify right triangles.
Understand that attributes belonging to a category of two-dimensional figures also belong to all subcategories of that category. For example, all rectangles have four right angles and squares are rectangles, so all squares have four right angles.
