This innovative work presents a "trigonometric hand trick" model to help students easily remember common trigonometric values. The model assigns specific angles to fingers on a hand diagram. Students can then use formulas based on the number of fingers above and below the angle finger to quickly calculate sine, cosine, and tangent values. The objectives are to help students recall values without rote memorization and to increase interest in mathematics learning. A procedure is provided to create the hand model using paper, markers, and glue. It is concluded that this creative approach can effectively teach trigonometric concepts while engaging students.Whole Numbers Addition & Subtraction

The document summarizes an article that argues for using inquiry-based learning to teach information retrieval. It outlines the author's experience using this approach over 5 years of teaching an undergraduate module. The author claims inquiry-based learning encourages deep learning and that information retrieval lends itself well to this method as there are no right or wrong answers. The strengths identified are that the argument is based on the author's experience, but weaknesses are that no student feedback or assessment results are provided to further support the claims.Rock It at Crockett promotions powerpoint

The document outlines the daily routine and learning process for a math class. It includes:
1. A warm-up with 4-5 review or new problems to introduce topics for the day. Class work is to be completed during class time and any unfinished work should be done outside of class.
2. New concepts are introduced through demonstration by the teacher, then practiced together through examples before students work independently.
3. Additional learning resources like online math sites are provided to support studying outside of class, since class time is limited to 60 minutes per day.
4. A short practice test is included covering translating expressions, order of operations, and fractions to gauge readiness.Ultimate guide to systems of equations

The document discusses various formulas used to represent lines in the coordinate plane, including:
- Slope-intercept form: y = mx + b, where m is the slope and b is the y-intercept.
- Point-slope form: y y1 = m(x x1), where (x1, y1) is a known point on the line and m is the slope.
- Standard form: Ax + By = C, where A, B, and C are constants and A and B cannot both be 0.
It provides examples of writing equations of lines in different forms given information like the slope, a point, or the graph of the line. Converting betweenFebruary 16 2016
