Our new math curriculum has a section for Common Misconceptions and even I learned something!!
"Some students may think that a bar-type graph is the same as a bar graph. Bar-type graphs have bars divided into individual cells to demonstrate one-to-one correspondence for each piece of data, whereas bar graphs have solid bars to demonstrate the total quantity for that category."
It all makes sense of course, but I've just never seen it written out an explained into such detail! Duh! We did our best to cover both bar graphs and bar-type graphs! :)
We used this freebie from Susan Pickens to review tally marks and create a bar-type graph. It worked perfectly!
We also created a new class graph or chart each day and discussed what we noticed on each graph.
The TEKS for this say-
(8) Data analysis. The student applies mathematical
process standards to organize data to make it useful for interpreting information
and solving problems. The student is expected to:
(A) collect, sort, and organize data in up to three categories using models/representations
such as tally marks or T-charts;
(B) use data to create picture
and bar-type graphs; and
(C) draw conclusions and generate
and answer questions using information from picture and bar-type graphs.
Oh, and I let them name all of the graphs and they were cracking me up!! I would take suggestions from the class and then we'd vote between two of them. We quite a range of basic titles like "The Pet Graph" on a graph of unique animals we'd choose to have as a pet and then some funny ones like "The Stuff That People Like" on a graph of our favorite school subjects. Haha!
