What’s covered in these Classifying Triangles by Angles & Sides notes? 

• Classifying Triangles by Angle- Acute, Obtuse, Right
• Classifying Triangles by Side- Isosceles, Scalene, Equilateral

What does Sally’s “gradual release model” entail? 

• 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 were 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 worksheets are common core aligned to 4.G.2 and 5.G.3 (classifying triangles by angles and sides).
