  1. Welcome back to:Using Manipulatives in the Secondary ClassroomClass#3: Geometry/Measurement Strand Please have a seat at the center table with your name tent. Please sign in to a computer – so that it is ready for later.

  2. Class 1: Review Show =1 =1/2 =1/4 =1/3 =1/6 =1/12 =1/24

  3. Class 1: Review Show =1 =1/2 =1/4 =1/3 =1/6 =1/12 =1/24 =1/8

  4. Class 1 Review Subtracting Integers: show (+5) – (-3) (+5) – (-3) = 8 or (+5) + ? = 8

  5. Class 1 Review Subtracting Integers: Corresponding addition problem How are they similar? How are they different? Problem from Above

  6. Multiplying Polynomials (x – 1)(x +4) (x – 1)(x +4)=x2+3x-4

  7. Dividing Polynomials x2 + 5x +6 x + 2

  8. Dividing Polynomials x2 + 5x +6 x + 2

  9. Dividing Polynomials x2 + 5x +6 x + 2 = x+3

  10. Factoring Polynomials x2 – 5x + 6

  11. Factoring Polynomials x2 – 5x + 6--- make a rectangle with the squares

  12. Factoring Polynomials x2 – 5x + 6 = (x-2)(x-3)

  13. NCTM-- ILLUMINATIONS

  14. Class 3: Strand 3 and 4: Geometry and Measurement Handouts • Standard 3 and 4 SC 6-8 • Geometry CLG’s Circles, Geoboards, Tangrams, & Geometer’s Sketchpad
