  1. 11/28/12-11/29/12 (GT) What makes a number a “perfect square? • Find Seat • Open notebook to notes section • and write date and lesson title • above. • Begin Warm-up – 10 min (work with partner) Obj: Students will be able to determine if a number is a perfect square or a perfect cube; list the first 15 perfect squares; and evaluate square roots of small perfect squares and cube roots of small perfect cubes. (CCES: MP.3, MP.7, Pre-8.EE.2)

  2. In Search of Perfect Squares Teacher will distribute “In search of Perfect Squares” worksheet with GEOBOARD Paper. Students will work with partners to complete activity (15 min). Once done, teacher will review answers and list first 15 perfect squares on the board.

  3. Independent Practice (HW) Teacher will distribute “Squares and Square Roots” worksheet to be completed by tomorrow. (5 min) Check out www.brainpop.com and search for square roots

  4. Square Roots in the Real World (2 min) • Home decorating: A remnant of carpet in the shape of a square is advertised as 16 square yards. That will cover an area that measures 4 yards by 4 yards. • Law enforcement: In order to find the speed of a car after a collision, an investigator can measure the length of the skid marks (L) and apply the formula: speed = 2 • Computer programming: Square root and absolute value functions are often used in computer programming to ensure a positive number is used for calculations.

  5. Summary (exit ticket) In your own words, what makes a number a perfect square? A perfect cube? (3 min)

  6. Day 2 To review with students prior days lesson, students will play Who has, I have…

  7. Day 2 Let’s talk about perfect cubes? (Teacher will distribute worksheet on perfect cubes and allow students to work in pairs. Discussion to follow)

  8. 11/28/12-11/29/12 (GT) What makes a number a “perfect square? • Find Seat • Take out sheet of paper • Sit quietly Obj: Students will be able to determine if a number is a perfect square or a perfect cube; list the first 15 perfect squares; and evaluate square roots of small perfect squares and cube roots of small perfect cubes. (CCES: MP.3, MP.7, Pre-8.EE.2)
