Previous Attitude They are adults. Let them find their own way. Current Attitude Force them to work hard.

16
The Bottom Line Students will only work as hard as you require them to work. If you want more from your students, then demand more.
17
Which Missing Skills Are Crippling Students in College? (…the same ones that cripple them in your classroom…) Simple Arithmetic Simple Algebraic Manipulation Graphing and Understanding Basic Shapes Simple Geometry Critical Thinking A Sense of Responsibility
18
Simple Arithmetic
19
Example – Basic Fractions
20
Example – Integer Manipulation
21
Solutions Restrict calculator usage. Encourage drill and kill arithmetic for 5 minutes each day.
22
Simple Algebraic Manipulation
23
Example – Facts Through Experimentation
24
(if they are proceeding to calculus)
25
Comments Not everything has to be memorized. Encourage students to experiment. We expose students to so much of the forest, that they don’t know the difference between an oak and a pine. Students need to be able to organize their work.
26
Example – Lines 1
27
Example – Lines 2
28
Example – Lines and Quadratics
29
Graphing and Understanding Basic Shapes
30

32
You Can’t Keep Yourself From Reading “Stop” (this is a different drill)
33
Example – Why Shape Is Important?
34
Example - Growth
35
Notes Your students will be required to create simple graphs without a calculator, and also think about the shapes of simple graphs. Your students should know everything about lines and parabolas (except foci), square root, 1/x, sine and cosine. Your students should have seen an asymptote.
36
Simple Geometry
37
What Geometric Concepts are Important? Pythagorean Theorem Areas of triangles, rectangles and circles. Circumference of rectangles and circles. The sum of the angles in a triangle. The facts associated with isosceles and equilateral triangles. Triangle trigonometry (if they are proceeding to calculus). Honestly, that’s it!
38
Combining Arithmetic, Algebra and Geometry
39
In General, We Are Happy If Students Can do simple arithmetic and basic algebra. Know everything about lines. Know everything about parabolas (except foci). Can solve linear and quadratic equations. Can factor simple quadratics, complete the square and use the quadratic formula. Have seen an asymptote. Know the shapes of basic functions (nothing tricky). Know the area formulas for circles, rectangles and triangles, and know the perimeter of a circle and a rectangle. *Know the trig functions at the special angles. Can organize their work.
40
Critical Thinking Can your students find the error in an argument? Can your students combine ideas without seeing a previous example? Do your student know the difference between a definition and an example?
41
Example – Simple Critical Thinking
42
A Sense of Responsibility This Is The #1 Employer Requirement!
