This week the 3rd grade class continued its work on graphs, moving on
from Bar Graphs to Circle Graphs and Line Graphs.
The Circle Graphs lesson was introduced with the hypothetical question
to the class of "how would you spend $1,000,000," with students having
to divide the money into purchases--as they saw fit--that totaled 100%
of the total. Next, to practice the skill, students completed the two
pages of book exercises.
Line Graphs were another area of focus, with students learning the
value of these graphs is to show trends or patterns, something that
Bar Graphs and Circle Graphs fail to do.
The teacher introduced the lesson by drawing a Line Graph showing
Inches of Rain/Per Month in Costa Rica. The teacher did this by
soliciting students' help in estimating monthly rainfall.
Also this week students completed In-Class #2, which had them create a
Bar Graph (of hours per week spent on three favorite activities) and a
Circle Graph (on how they would spend $100).
