## Lesson Plan # 24 - Review of Lessons 1 - 14

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

2. (5 min) Review of homework #23 (<= 3 problems)

3. (10 min) Review of the first half of the year.
Just work through the following problems, asking the students for help:
1. Fractions:

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

3. Angles:Find angle "A":
4. Negative numbers:
```       8  -  12  = - 4
- 4  -   4  = - 8
(- 4)(- 4)  = + 16
```
(Remind students that parentheses next to each other means multiply)
5. Algebra: For A = 6, B = 9, C = 3:

A - B = 6 - 9 = - 3

Solve:

3A - 88 = 32
3A = 120
A = 40
4. (Remainder of class) In-class Exercise.

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