Find measures of complementary, supplementary, vertical, and adjacent angles

Find measures of complementary, supplementary, vertical, and adjacent angles

What you'll learn

  • Identify the greatest common factor (GCF) of two whole numbers up to 100 with 80% accuracy on a worksheet.
  • Apply the distributive property to factor out the GCF from expressions of the form a(b + c) where a, b, and c are whole numbers less than 20, completing at least 4 out of 5 problems correctly.
  • Explain, in writing, the steps involved in factoring an expression using the distributive property in their own words, demonstrating understanding of the concept with a score of 3 out of 4 on a rubric.
  • Solve real-world problems by factoring expressions using the distributive property, showing all work and arriving at the correct solution for at least 2 out of 3 word problems.
