Welcome Back!

We are so glad to meet to you a second time this year.
Please give us a comment and let us know how you math classes are going this year.
Thanks for being here and for "ALL" you do.
Tina, Rhonda, and Carol

LoTi Resources

Baby Name Voyager
LoTi 3: Cool! Cool! This website lets students interpret area graphs based on the popularity of names over the last 100 years. Wonderful, unique example of line graphs at work.

What's in a Name
Students explore sets of names and create bar graphs, pictographs, glyphs, and circle graphs. They also find the range, compute measures of center, and create box and whisker plots. The process standards of Representation and Communication play a major role in these lessons.

The Game of SKUNK
In this lesson, students practice decision-making skills leading to a better understanding of choice versus chance and building the foundation of mathematical probability. This lesson is adapted from an article by Dan Brutlag, "Choice and Chance in Life: The Game of SKUNK," which appeared in Mathematics Teaching in the Middle School, Vol. 1, No. 1 (April 1994), pp. 28-33. LOTI 3

What is the Chance of Rain?
There are long-term events that happen year after year and affect the rainfall pattern. The Bureau of Meteorology analyzes the past patterns and tries to predict the future patterns. The predictions are presented as probabilities (chances) and published to help people make informed decisions. LoTI 2

Explorations with Chance
LoTi 3: In this lesson, students analyze the fairness of certain games by examining the probabilities of the outcomes. The explorations provide opportunities for the learning phases of predicting results, playing the games, and calculating probability ratios. Students should have had prior experiences with simple probability investigations, including flipping coins, drawing items from a set, and making tree diagrams. They should understand that the probability of an event is the ratio of the number of successful outcomes to the number of possible outcomes.

Heads or Tails
A virtual coin flip aids in learning about probability. Level 2

Interpreting Graphs

Bar Graph - Enter data to create a bar graph, then manipulate the graph's maximum and minimum values

Fun and Sun Rent-a-Car - students use tables, graphs, linear functions to solve a real-world problem

Graphing Jeopardy Game - [this link opens on a new page] Review graphing terbs and information this fun way

Interactive Graphs - large number of interactive graphs related to social studies topics

Magic Bullets: Chemistry vs. Cancer - In this activity students will work with data about cancer deaths. The purpose of the activity is to give students some experience in reading and interpreting graphs. There is a worksheet associated with the data sets

Using Graphs to Understand Data - online quiz

Graphs and charts - four different graphs and charts for you to consider

Circle Grapher - Use this tool to graph data sets in a circle graph. You can input your own data or alter a pre-made data set

The High Stakes World of StatisticsThis 26 minute video from United Streaming (requires membership) contains 8 segments. They are targeted to grades 9-12, but some segments would be suitable for middle school.Description:What's the chance you'll draw a face card out of a 52-card deck? That's one of many questions related to probability! Find out about probability and more. © 2002 Standard Deviants
