- (5 min) Mental Math
- Start with 58, subtract 22, then take the square root [6]
- What is the area of a triangle whose base is 8 in. and whose height is 7 in? [28 sq. in.]
- What is 2 1/2 + 2 1/2 + 2 1/2 + 2 1/2? [10]
- What is 800 x 20? [16,000]
- What is 30% of 90? [27]

- (5 min) Review of homework #23 (<= 3 problems)

- (10 min) Review of the first half of the year.

Just work through the following problems, asking the students for help:

*Fractions:*

(Let students change this to a mixed number)*Geometry:*Find the area of the shaded part:

*Angles:*Find angle "A":

*Negative numbers:*

8 - 12 = - 4 - 4 - 4 = - 8 (- 4)(- 4) = + 16

(Remind students that parentheses next to each other means multiply)*Algebra:*For A = 6, B = 9, C = 3:

A - B = 6 - 9 = - 3

Solve:

3A - 88 = 32

3A = 120

A = 40

- (Remainder of class) In-class Exercise.

- Hand out homework as students successfully complete the in-class exercise.
