Paper Clip Chains and Graphs

by the whole class, Typed by Mr. McGaughey

Last week, we recorded how many paperclips we could link up in 2
minutes. We each made our own chain. We made a bar graph which shows
how many people made each length of chain. We used up half of the
school’s paperclip supplies (but we put them back). The longest
paperclip chain was 29 paperclips. The shortest chain was 5 paperclips.
The average chain was about 16 paperclips.

The purposes for this exercise were:

• Predict results, collect and organize data, and find the range.

• Construct a bar graph using appropriate intervals for the range of
data.

Here is a picture of our graph.

Coming Up in Grade 4: December 1-9

Language Arts: We are reading and responding to Christmas and winter
stories.

Math: Chapter 3: Graphing: Over the next 2 weeks we will be learning
about various ways to collect and organize data, making pictographs and
bar graphs by hand and using a computer. Your child will also learn how
to interpret and extend different types of graphs and tables.

Science: Over the month of December, we will be doing a variety of
investigations and experiments to study the properties of sound.

Social Studies: We are continuing our study of Canada and its regions.

Phys-Ed.: We are doing a unit on pre-volleyball skills.
