1.) Students will estimate the square root ot 56, explaining their thinking and their answers 
2.) Students will solve the following:
 
  • (4)(4)(4)(4)(4)(4) x (4)(4)
  • (5)(5)(5)(5)(5)(5)(5)(5) / (5)(5)(5)(5)
  • (7)(7)(7)(7) x (7)(7)(7)(7)(7)(7) 
    3.) Students will solve problems like the following and explain their answers:
  • A video tape will record 6 hours in the EP mode. Jim has already recorded 2 5/6 hours of football. can he record another 3 1/2 hours of basketball?
  • A rectangle has a width of 1 1/2 inches and an area of 5 1/4 square inches. What must you do to find the perimeter of the figure? Explain and give the perimeter. 
    4.) Students will show their understanding of absolute value:
  • Use two integers and the terms "integers," "opposite," and "absolute value" in a sentence that explains the relationship of the three terms.
  • Solve for x: I x I = 5 I x + 1 I = 8

  • 1.) Students will solve the following equations, show their work, and explain their processes: 
  • (6)(6)(6)(6)(6) x (6)(6)(6) = t;
  • (7)(7)(7)(7)(7)(7)(7)(7) / (7)(7)(7) = ;
  • (4)(4)(4) x (3)(3)(3)(3) = 
    2.) Students will give the square root of the following, estimating if it is not a perfect square:
  • Square root of 121 
  • Square root of 64 
  • Square root of 34
  • Square root of 15 
    3.) Students will solve the following:
  • 3 2/5 + 7 1/3 = 
  • 24 - 5 2/3 =
  • 15 1/3 / 1 /12 
    4.) Students will solve for x:
  • I x I = 6
  • I x - 5 I = 3
