In EDM, students worked with positive and negative integers in Lesson 6.3: Addition and Subtraction of Positive and Negative Numbers.  Students briefly worked in their EDM Journals, but then we transitioned into the Pre-Algebra's Power Point.  We completed some example problems using Khan Academy and then broke out into pairs to complete  2.1 Adding Integers Practice C .
In class, students...

• completed a Quick Check by computing solutions to three substitution problems.
• Solve 4y + 8m if m = 5 and y = 3.
• Solve 32 - g * u if g = 17 and u = 9
• Solve 9 + y * d if y = 10 and d = 7
• calculated sums and differences when working with positive and negative integers.
• collaborated with a peer to complete  2.1 Adding Integers Practice C .
• self-checked their work using a teacher created answer key.

For homework, students SHOULD...

• complete Lesson 2.2 Subtracting Integers Practice A.
• review the Khan Skill that was assigned on Monday.

In Pre-Algebra, students reviewed answers from last night's homework that dealt with the surface area of prisms and cylinders.  Students then began Lesson 6.9: Surface Area of Pyramids and Cones.  Some new terms that were discussed were slant height and regular pyramid.  
In class, students...

• completed a Quick Check dealing with the two problems listed below:
• A rectangular prism is 0.6 m by 0.4 m by 1.0 m. What is the surface area?
• A cylindrical can has a diameter of 14 cm and a height of 20 cm. What is the surface area to the nearest tenth? Use 3.14 for p.
• asked questions dealing with last night's homework.
• developed an understanding for calculating the surface are of pyramids and cones.

For homework, students SHOULD...

• Pgs. 320 - 322: 1 & 2, 9 - 12, 19 - 24.
