CALENDAR and UNITS for SEMESTER 1 of PRE-ALGEBRA.
This school year, we will be covering the following. All dates are according to the Akron Public Schools pacing guide, but can/will be adjusted by me as needed. Also, all assessment dates are a goal, but may be adjusted as needed. Not only will there be formal assessments, but there will be several informal assessments of learning, including observation of classwork/homework, participation in class, group work and discussions. The indicators (objectives) for each unit are numbered.GRADING PERIOD 1
Unit 1 Data Analysis September 1 – September 22

- Explain the mean’s sensitivity to extremes and its use in comparison with the median and mode. [DAP8C5]
4. Compare two sets of data using measures of center (mean, mode, median) and measures of spread (range, quartiles, interquartile range, percentiles). [DAP8D4]
5. Make conjectures about possible relationship in a scatterplot and approximate line of best fit. [DAP8F6]

An important note concerning homework, classwork, and bellwork: Full credit is given for honest completion of entire assignment. I do not check right or wrong. IF YOU DO ALL OF THE WORK, YOU WILL GET ALL OF YOUR POINTS. The idea of homework, classwork and bellwork is to practice what we are learning. We will go over as many of the problems from each particular assignment as necessary in order to achieve mastery of that particular concept. Bellwork will be overall skills review in order to keep up for the OAA in the spring.
Once again, I hope you find this useful. It is long and detailed, but I do want you to be fully prepared for what is coming up this semester. I will go over the objectives with you in a way that I hope will bring understanding/comprehension.
I plan to be available for tutoring/extra help on certain days after school. I will let you know specifically when that is.
I hope this school year is a good one for you, and for the class as a whole.
