WHAT'S MY NUMBER?

Introduction: Students will be on an information quest using the Internet to find facts needed to arrive at a number on the 100 board, a number known only to the author of the quest. Students will use the information to work math problems using the 100 board . This lesson plan may be adapted to any grade level and maybe integrated with other subject areas. This is dependent on the teacher and the skills targeted for the student.

Teachers who are teaching remedial skills will find this easily adaptable.

GATE Teachers: Once students have learned how to do this, they may design their own quest for other students.

Prior Knowledge: How to use the Internet, math skills and math vocabulary appropriate for grade level.

Grade Levels: K-3 This lesson plan is for 1st grade, 4th quarter. (It may be modified for any grade level)

Objective: Student will use the Internet to find information needed to work various math problems using the 100 board to arrive at the number answer. For this lesson plan, the skills targeted are:

addition, subtraction
number recognition to 100
solving addition and subtraction problems with one- and two-digit numbers
understand the meaning of the symbols +, -
make precise calculations and check the validity or the results from the context of the problem.

Note: For upper grades you will need to design the problems to fit the particular skills you are teaching and you will need to go to web sites that are of higher reasoning than the one on the student page. The two that appear at the bottom of the page may suit your needs.

Resources: 100 board and access to the Internet, although for lower grades the teacher may give information to the student.
Refer to the 100 Board page for a 100 Board ready for your use (HTML) (PDF)

Process: Explain to students they will be on an information quest using the Internet and they will be doing math problems using the 100 board to arrive at a number known only to you.
Refer to the student page for a lesson already prepared for your use (HTML) (PDF)

Learning Advice: If you are not familiar with the 100 board or how to use it, I have included a 100 board and a tutorial on how to use it.
Refer to 100 Board Tutorial.

Evaluation: You will be able to assess student success by whether or not the student arrived at the correct answer. If the answer from the student is wrong have the student work it again. If wrong more than twice, the teacher will need to follow-up with the student to see where the student's calculation is incorrect. The kids really like doing this. They can find out all kinds of neat facts that are only limited to the stretches of your imagination.

I found a couple of sites that you can explore to find "number fact questions" for your own "What's My Number"

Eisenhower National Clearing House http://www.enc.org/

This one is a wealth of different subjects you can use to find number facts.

Math Resources Virtual Lessons http://www.eduref.org/cgi-bin/lessons.cgi/Mathematics

Mega Math http://www.c3.lanl.gov/mega-math/

Extensions: For primary you will need to teach how to move on the 100 board ex: straight up and down for adding or subtracting 10's. To get them ready for the Internet, do several "What's My Number," using facts they already know.

ex: Start on the number of legs on a horse, - the # of legs on a bird, + the # of noses on a pig, + the # of pennies in a dime, etc.

Students may work in pairs or groups.

For upper grades you can take the fact number you have found and turn that into a problem before they can move on the board.

Conclusion: There are no limits to the possibilities you can come up with for "What's My Number"
