Area of Parallelograms

Today we explored parallelograms and found that they relate to rectangles and we find area the same way!  Area = base x height

Tonight's homework:  You may use a calculator and need to show your work!

They use big numbers in the video below, but the concepts are the same!

Triangles

Sorry, this didn't post on Wednesday...

Today we worked on finding the area of Triangles.  We saw that one triangle is half of a rectangle, so we take our formula for finding the area of a Rectangle, b x h, and divide it by 2 for a triangle.

  

Base x Height divided by 2

Happy "Spring"

Well it's freezing cold and we're expecting snow, so happy first day of spring!!!

We have our Statistics Test on Wednesday, March 25th.

What’s On the Statistics Test???

1)  Be able to identify what is and is not a statistical question.

2)  Be able to answer questions that require you to read a graph or a chart for information. 

« Bar Graph ~ a bar graph uses vertical or horizontal bars to display numerical information.  The length of the bar tells you the number it represents.

« Histogram~ looks like a bar graph, BUT the bars are connected and a histogram is used when you need to group the data because you have so many different numbers in your data

« Box-And-Whisker Plot ~ shows the range and distribution of data along a number line.  It is broken into four equal quartiles, highlighting the five number summary of the data. 

« Line Plot ~ shows the shape of the data.  This uses a line and Xs to plot the data.

« Tally Chart and Frequency Chart ~ used to collect and summarize data.

  

3)  Be able to calculate mean, median, mode, and range.

□   You have a sheet of cardstock paper with directions on how to calculate each of these.

□   Be able to defend when to use the mean, median, or mode.

4)  Be able to take information and produce a graph.

All graphs must have:

□   a title

□   the horizontal and vertical axes labeled

□   the graph must start at 0 where the two axes meet (horizontal and vertical)

□   the scale (numbers used) needs to be at equal intervals (0, 5, 10, 15…)

□   the scale must be appropriate for the numbers used

□   the scale numbers must be on the outside of the graph

□   use lines (“tic marks”) for the numbers

□   the population must be stated

For Bar Graphs:

□   bars must not be connected to the vertical axis ~ there must be a space

□   bars must not be connected to each other and must be the same width

□   bars must be equal distance apart ~ the space between the bars must be the same for each bar

For histograms:

Same as a bar graph EXCEPT:

□   the bars are connected to each other

□   the data is grouped (Remember our height activity – we grouped students 50-53 inches tall and so on)

For box-and-whisker plots:

□   used to show the variation of the data – how it is distributed across a number line

□   the five number summary (low value, lower quartile, median, upper quartile, and high value) are plotted above a number line, with a box drawn around the median, through the lower and upper quartile values.

□   The size of the quartiles show how the data is distributed.  Small boxes and whiskers indicate that the data is clustered in a small area.  Broad boxes and long whiskers indicate that the data is spread out (a larger range). 

□   The box shows the middle 50% of the data values.

For a line plot:

□   uses a number line to represent the data

□   places an X at each number represented in your data

□   Xs must be the same size and height

□   has a title and a label for the horizontal scale

5) Be able to determine an appropriate scale to be used on a graph.

« The scale of a graph is the “ruler” that measures the height of the line or bar.

« The interval is the amount of space between the values on the scale.

6)  Know the difference between a tally chart and a frequency chart.  Be able to create each one when given data.

Have a great weekend!

Statistical Questions

Today we began talking about Statistical Questions.  This video can help you define what makes a Statistical Question:

Our Criteria are:
1. There must be a defined population or subject
2. There must be more than two possible answers
3. The data must be able to be represented numerically

Quiz Next Thursday, February 20th

Tonight's homework:  

-Miss K  :)

Dividing Fractions

Today we began dividing fractions!  Please find examples from class below and some videos to help you with tonight's homework.  If you have trouble with the HW and the notes and videos don't help, please have a parent/guardian sign off on the work you have completed!  Thanks!!!  If you were absent today, I would like to go over dividing with you before you try it at home.  Please talk to me during class Wednesday.

-Miss K  :)

Multiplying fractions

Tonight's homework is to practice multiplying fractions.  Many of you finished or came close to finishing during class, so there shouldn't be too much to do tonight!  Consult the notes below and on the back of the HW paper if you are stuck!

Have a good night!

-Miss K  :)
