## What is a fraction? Go to the Big Book Center. Read Bruce McMillan’s Eating Fractions. After you read it, go to http://www.aaamath.com/B/fra16_x2.htm to learn more about fractions. Get out your Math Notebook and write three sentences and draw at least two pictures to complete this sentence, “A fraction is…” When you finish, show it to one classmate and to me! I will give you a graham cracker. Be ready to show me how to break it into halves and fourths!

Listen to Jerry Pallotta’s Pizza Fractions  in the Listening Center.

Go to http://www.primarygames.com/fractions/start.htm and play Pizza Party!

When you finish, make your own pizza fractions and use them to answer the questions on the “Fractions by the Slice” worksheet in the math center. Guess what? We’re going on a field trip to Cici’s Pizza to make real pizzas and cut them into fractions!

Play the fraction game at http://nlvm.usu.edu/en/nav/frames_asid_103_g_1_t_1.html

Work with a partner using the geoboards to show the fraction. Use one rubber band! Write the fraction on a dry erase board! First, see how many ways you can show ½ and ¼! What other fractions can you show?

Play a matching game to see if you can reveal the hidden picture! Go to http://www.hbschool.com/activity/con_math/g03c21.dcr.

and play the fraction game called Cross the River.

Play Melvin Makes a Match at http://pbskids.org/cyberchase/games/equivalentfractions/index.html.

Find a partner and play Fraction Five in a Row! Read the task card carefully!

I have a brown paper bag. In my bag are some color tiles. Can you guess my riddle? Use the color tiles to solve my riddle. I will give you four clues.

There are 6 tiles.

None are green.

½ are yellow.

The other half is blue.

Show me the tiles!

Open the bag! Did you solve it? Now you make one up for a classmate. Be sure to give clues that help your partner solve the riddle. Choose up to 12 color tiles.

Play Fraction Top-It  with a partner using the Everything Math Deck of cards. Complete the game record sheet. After you finish, complete the “Thinking About Itworksheet. Be sure to draw the fraction and explain how you know who wins the round of Fraction Top-It. Share this with one classmate and me!

Use the Fraction Tiles to play Cover Up. Read the instructions on the task card carefully. The first player to make one whole is the winner! Good luck!

CHALLENGE!!!  If you dare…

Teacher Information

Purpose

This WebQuest will allow students to explore fractions. The activities are in addition to teacher-directed lessons from the Everyday Math book. These games and tasks will allow extra practice or extension of class instruction. Many formative assessments can be conducted throughout this WebQuest.

Preceding and Ensuing Events

Preceding this WebQuest, students may have heard about fractions in kindergarten. Otherwise, the first stages of this WebQuest will begin the Friday before we begin the instruction in class. Ensuing events include revisiting fractions in our curriculum, later, in May, with much more complex activities including comparing fractions and exposure to concepts not in our standards.

Debriefing

This WebQuest should motivate students to learn about fractions. It will familiarize them with some games and Web sites. The cross-curricular writing tasks will help students learn to write clues and reflect on their learning.

Description

The activity could be improved by adding the fraction song. It would be fun to have it as a clickable link where students could listen to the song.
