Assignment: 04-Stem and Leaf Plots Stem-and-leaf plots are just another way of representing data.  Stem-and-Leaf plots work best if all of the numbers in the data set are greater than 9 and less than 100 (between 10 and 99). Let’s say … Continue reading →

Assignment: 03-Frequency Table and Line Plots As we learn in science, the word frequency means how often something happens.  A frequency table takes a set of data and tallies the amount of times certain bits of data happen.  It can either … Continue reading →

Assignment: 02-Mean Median Mode Range For this section, I will use the data pictured below. We’ll say this is a student’s scores for 8 tests. Range - the distance between the highest number and the lowest number.  In this set of data … Continue reading →

Assignment: 01-Samples and Surveys This unit begins our unit on statistics.  Much like the word algebra, the word statistics alone can make things seem word than they are, so we begin simply by defining what the word statistics means: Statistic - a … Continue reading →

12-Graphing Shapes Previously in the year we have discussed graphing on a coordinate plane.  To review this, click here. There are a few different ideas that we introduce in this lesson.  The first is if you are given a set of … Continue reading →

Assignment: 10-Volume Practice: 11-Surface Area and Volume Practice Once you are familiar with area, volume comes a bit easier.  There is just one simple formula. V = B x h Notice, I used a capital B.  This represents the area of the … Continue reading →

Assignment: 07-Surface Area Practice 1: 08-Surface Area Practice Practice 2: 09- Surface Area Practice 2 Practice 3: 11-Surface Area and Volume Practice When dealing with surface area, we need to notice that key word area. We are still dealing with just two dimensions.  Think of … Continue reading →

Assignment: 05-Solid Figures Nets: 06-Solid Figure Nets Cube – 6 sided figure, all sides are squares, all 90 degree angles  Rectangular Prism – 6 sided figure, all sides are rectangles, all 90 degree angles  Rectangular Pyramid – Rectangle base with four triangle … Continue reading →

Assignment: 03-Area of Triangles and Parallelograms Practice: 04-Perimeter and Area Practice I want you to take a look at the rectangle below: Using the formula we previously learned in Area of Squares and Rectangles, l x w, we could calculate that the … Continue reading →

Assignment: 02-Area of Squares and Rectangles Practice: 04-Perimeter and Area Practice Area is defined as the amount of space inside the boundaries of a two-dimensional shape.  Look at the square below. You will notice in the larger square above there are 9 … Continue reading →
