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