  5. Period 6 – Writing Numerical Sentences Assign variables and write the verbal sentence as a numerical expression. • Mr. Quintanar is 10 years older than Mrs. Scull. • Mr. Razo has taught 20 years fewer than Mr. Ellis. • Mr. Forsythe is 13 years more than one-fourth Mrs. Dolezal’s age. • The number of students in Ms. Macias class is 5 more than double the number of candy bags she recently purchased.

  6. Period 6 – Writing Numerical Sentences Assign variables and write the verbal sentence as a numerical expression. • Mr. Lewis may be 17 years older than Mrs. Scull. L = Mr. Lewis; S = Mrs. Scull L = S + 17 • Mr. Razo has taught 20 years fewer than Mr. Ellis. R = Mr. Razo; E = Mr. Ellis R = E - 20 • Mr. Forsythe is 13 years more than one-fourth Mrs. Dolezal’s age. F = Mr. Forsythe; D = Mrs. Dolezal F = 1/4D + 13 • The number of students in Ms. Macias class is 5 more than double the number of candy bags she recently purchased. S = Students; C = Candy S = 2C + 5
