Space Coupe to the Rescue
By choosing a positive or negative number, the player controls the vertical position of a spaceship. If the spaceship reaches the same vertical position as a virus pod, the pod is destroyed.

We continued to work on negative numbers today.  Pre-Algebra needs to complete Skills Practice Workbook pages 9-10 (the odd problems only) by Monday.  We will have a quiz Monday over adding and subtracting integers and a test Tuesday.

5th & 6th Periods: Worksheet, Homework 1.2

7th Period:  p. 108, # 12-44 even (7th period is doing work from the book because of their behavior)

I will be out tomorrow for a meeting of the Key Leaders Network.  I am sure that I will learn a lot while I am there.  Students will work on review for the Progress Monitoring test that will be given on Friday.  This test will measure their progress on the following objectives:

• Determine measures of central tendency (mean, median, mode) and the range using a given set of data or graphs including histograms, frequency tables, and stem-and-leaf plots.
• Use the order of operations to evaluate numerical expressions.
• Translate verbal phrases into algebraic expressions and algebraic expressions into verbal phrases.

We have begun the study of negative numbers this week.  Pre-Algebra has begun to add and subtract integers.  Their homework tonight is p. 73, #14-25 all.  Math is exploring a unit called Accentuate the Negative that gives an in-depth understanding of negative numbers.  Their homework is a worksheet called Homework 1.1. 

 We are also working on how to behave during a group discussion.  Research shows that students learn more when they are given the opportunity to discuss what they are learning.  This is a skill that takes some time to develop, but is well worth the effort.  According the the Alabama Course of Study: Mathematics, 2003,

The seventh-grade mathematics classroom environment encourages communication, exploration, and risk taking that are critical as students become more confident and learn to exist in an ever-changing world (p. 36).
