Davis’ Daily Drama

Today students adopted an egg and had to ensure it’s safety while bungee jumping off of a cabinet.  We used the math we learned last week: line of best fit.  Students had to predict the exact amount of rubber bands needed to ensure a safe and thrilling jump for their egg.  Unfortunately, several eggs had to receive medical attention, but they should all be back to their old selves within the next week or two

Homework:  Please finish the shoe size/height task – it will be due tomorrow

Today we learned how to find the line of best fit.  Here are the notes from today: Line of best fit

Homework: pg 417 worktext.  Also, please get the data for the line of best fit task.

Today we worked on inequality word problems.  Here are the notes from today: inequality word problems 2010

Tomorrow we will review for our equations and inequalities test which will be on Thursday.

Homework: finish class word problem packet.  Textbook pgs 658-659 #’s 7, 14, 16, 17, & 24.

Study session 8:15am tomorrow

Test Thursday!!!

Today we practiced graphing inequalities and then we learned how to write inequalities for given graphs.  Here are the notes from today:

graphing inequalities and finding inequalities from graphs

Steps to writing inequalites from graphs:

• Identify the y-intercept (if clearly located)
• Identify the slope
• Which side is shaded? (above is › and below is ‹)
• Dashed or solid line? (solid is also equal to, dashed is not equal to)
• Plug the information into slope-intercept form.
• **If you do not have a clear y-intercept, you can use the slope and a point to find the equation by using the point-slope form and then solve for “Y”**

Homework: finish pg 44 red workbook if you did not do so in class.  Do pg 197  on the worksheet I handed out in class.

Today we started graphing inequalities.  Remember the following rules:

• Plot the points like you would with an equation in slope-intercept form.
•    > or <  is a dashed line
•    ≥ or ≤ is a solid line
•    > or ≥  is shaded above the line
•    < or ≤ is shaded below the line.
•    Check your shading by picking 2 test points (one on either side of the line) You shade the area where the point is a solution to the inequality.

Here are the notes from today: graphing inequalities 2010

Homework: Pg 407 all in the Worktext.

Today we reviewed how to graph equations and how to determine an equation from a graph.  Students were also given a graphic organizer on the different forms for equations (Standard, Slope-Intercept, & Point-Slope).  We will also have a short quiz tomorrow on these topics. 

Check out the new links that will help you with equations → → →

Homework: Worksheet – due tomorrow for ACCURACY!!

Today we practiced writing equations in slope-intercept form from a point and a slope.  We also looked at parallel lines and finding an equation of a line that is parallel to a given line and a point.

Homework: correct you quizzes on a seperate sheet of paper. These are due Monday for a grade!!!!

Today we started point-slope form.  Students took notes on this concept and we practiced it during class.  The students did well on the class work as we went over each problem.  Here are the notes from today:

 point-slope form 2010

Class work was pg 395 in the green worktext. 

Homework: finish classwork and then do the worksheet that was handed out in class.

Today we took a quiz on slopes. 

Homework: do page 625 (all) in the textbook

Today we reviewed slope and slope-intercept form.  Students will have a quiz on Tuesday over this topic.  They will need to know the following:

How to find the slope from two points, how to determine the slope of a line from a graph, the rate of change from a table, and what type of slope is shown (positive, negative, zero, undefined)

Homework: Study for the quiz!
