Subject: Math Day 3

Illinois State Goals: 6. Demonstrate and apply a knowledge and sense of numbers, including numeration and operations, patterns, ratios and proportions
8. Use algebraic and analytical methods to identify and describe patterns and relationships in data, solve problems and predict results

Instructional Objective:
Students will solve a variety of addition, subtraction, multiplication, and division problems to find out interesting facts about spiders.

Supplies:
* transparency

Anticipatory Set:
* I will ask the students to guess how many pounds of insects a spider eats in one day. In one year? How about all of the spiders in the world? I will let them grapple with this question for awhile before I tell them the truth: The weight of insects eaten by spiders each year is more than the weight of all the people on earth.
* I will let them be amazed, and then explain that we will find out some more interesting facts in our math lesson

Activities:
1. I will turn on the overhead and put up a transparency with a variety of math problems, along with spider facts
2. I will cover up the spider facts, though, so only the math problems are visible to the students. I will tell them to take out a sheet of paper on which they will work their problems.
3. I will ask them to complete the first math problem at their desks. When they have found an answer, they should raise their hands.
4. I will call on a child to tell me the answer. I will write the correct answer next to the problem. I will, then, uncover the fact for that problem and write the answer in. I will ask the student who told me the answer to read the fact aloud.
5. I will continue in this fashion until we have completed all of the problems.
