### How Do I Do It?

Gather Bird Information and Measure Bird Feeder Materials
1. Invite your child to observe the birds around your neighborhood. Explain that bird feeders are a fun way to attract birds. Today you get to make one using fractions!
2. If you have individual measuring cups, have your child lay them out from smallest (1/4 cup) to biggest (1 cup). If you have a single measuring cup, help your child identify the fractions on the side of the cup. Explain that a fraction is a part of a whole.
3. Measure ¼ cup of each of the following: peanuts, raisins, sunflower seeds and cranberries. Pour these into a mixing bowl.
4. Explain to your child that the four parts of the birdseed mixture equal one whole batch of birdseed. Then ask:
• Seeds make up what fraction of the mixture? (1/4)
• Nuts make up what fraction of the mixture? (1/4)
• Fruits make up what fraction of the mixture? (1/2)
5. Measure 1/3 cup peanut butter.
• How many 1/3 cups of peanut butter would it take to get one cup?

Build your Bird Feeder
1. With a dull knife, spread the 1/3 cup of peanut butter over the outside of the pinecone or whole fruit.
2. Roll the pinecone or fruit in the birdseed mixture.
3. Tie a string to the top of your bird feeder and hang it from a tree branch.

Note: Birds enjoy a variety of healthy nuts and fruits; however, confirm that any substitutes are appropriate for your local species.

### Take It Further

1. Observe the bird feeder daily to estimate what fraction of the food has been eaten. Keep track of the fractions in a notebook.
2. Use tally marks to keep track of the different kinds of birds that ate from the bird feeder during a period of time. Add up the tally marks for each kind of bird and then use fractions to compare your findings. (For example: 8 kinds of birds ate at the feeder, two of them were Cardinals, so 1/4 of the birds eating at the feeder were Cardinals).
