Bar graphs and pictographs - 2nd grade math lesson
We solve various word problems concerning two graphs: a pictograph (or a pictogram) and a bar graph. The pictograph has to do with books in a library, and one symbol of a 'book' means 30 books. We use the picture symbols to find how many MORE history books there are than math books... which is quicker than calculating the actual quantities and subtracting them.
Then, the bar graph is about prices of washers in different stores.
This lesson is meant for 2nd grade math but is of course suitable also for students in higher grades.
