Kickstart your math class with this engaging “Do Now” warm-up slip! Designed for 7th-grade students, this quick activity gets students thinking about triangle angles, equations, and scale factor applications as soon as they enter the classroom.

How It Works:

• Students solve for a missing angle in a triangle by writing an equation.
  
• They apply a scale factor to a triangle-shaped sign, calculating new dimensions, areas, and the factor by which the area increases.
  
• The activity is designed to be completed independently in just a few minutes, making it perfect for the start of class.
  

Skills Practiced:

• Solving for missing angles in triangles
  
• Writing and solving basic equations
  
• Applying scale factors to dimensions
  
• Calculating areas and understanding how area changes with scaling
  

Teacher Tips:

• Collect completed slips in a class tray for quick review or spot-checking.
  
• Use this as a daily warm-up to reinforce previous concepts while previewing upcoming lessons.
  
• Can be adapted or combined with other warm-ups to create a series for consistent practice.
  

What’s Included:

• 1 “Do Now” slip with two multi-part problems covering triangle angles and scaling
  

Perfect for daily warm-ups, bell work, or quick review, this slip encourages critical thinking and reinforces key 7th-grade math concepts in a short, manageable format.
