Introductory Activity :

Presentation
1. Teacher will review the math terms needed for this activity.
2. Teacher will show the students a variety of bar graphs.
3. Teacher will show one resource material about the rainforest and use it to discuss the rainfall levels in the rainforest.
4. Teacher will do the same with a resource about rainfall levels at home.
5. Teacher will show a sample graph made using the aforementioned resource material.

Body :

Guided Practice
1. Teacher will model creating a graph of each level of rain. During the modeling, teacher will ask for the students input. For example, the teacher may ask, ?How do I determine the average rainfall for a one year period?? The students will respond. This allows the
students to demonstrate their knowledge of the terms as well as gives the teacher the chance to check for understanding.
2. Teacher will show the two graphs and discuss the differences asking for students input
to make the comparisons.

Independent Practice
1. Students will each be given one resource material from each of the two areas.
2. Students will create a graph for each rainfall level.
3. Students will then work in groups of 4 or 5 to create a large graph of the two rainfall
levels.

Conclusion Activity :

Closure
1. Students in their groups will share their graphs with the class and discuss the differences in the rainfall levels.
2. The large graphs will be posted on a bulletin board for the students to study more in-depth at a later time.
3. Teacher will point out the vast difference in the rainfall levels.

Vocabulary Words :

• bar graph
  
• inches
  
• measure
  
• rainfall
  

Evaluation Activity :

Evaluation:
Students will be assessed throughout the lesson. Teacher will check for understanding when reviewing the math terms, when making the sample graphs, and when discussing the graphs. As the students work independently, the teacher will circulate to offer support and assistance as well as to assess understanding. When the students work in groups of 4 or 5, they will help to evaluate each other and the teacher will circulate at this time as well. As the groups present their graphs to the class, student understanding will be evident and at this time the teacher can assess whether or not the concept needs to be re-taught.

Extension and Enrichment:
The students will take home their individual graphs and write a paragraph discussing the differences and similarities between the two rainfall levels. The students may also choose to seek out additional resources and create a new graph to present to the class.
