Age

5.

Materials

  • Red fraction circles in green frames (ten circles: 1 is undivided and the others are divided into 2 -10 equal parts.
  • Label with fractions written on them: 1, 1/2, 1/2, 1/3
  • Pencil and paper
  • Skittles

Preparation

This is an individual presentation.

Presentation

Naming

  1. Have the child bring over the first tray of fractions.
  2. Take out the whole circle. Directress tells the child “This is a whole.”
  3. Place the whole in front of the tray.
  4. Directress takes out one of the group of 2 and say, “This is a 1/2”.
  5. Place it in front of the tray.
  6. Repeat in this way up to the group of 5. (1/2)
  7. Directress does a Three-Period Lesson for the group of 1, group of 2, group of 3, group of 4, and group of 5.
  8. Once the child is familiar with this tray, do the same for the second tray.

Writing

  1. When the child knows the names, begin with the two trays.
  2. Directress points to a few fractions and ask the child what it is.
  3. This will serve as your check to see if the child knows the names.
  4. Tell the child that you will show him how to write fractions. 
  5. Point to the group of 2. Ask the child how many pieces there are. (2) .
  6. Directress says, “Yes, there are two pieces, so I will write a 2.”
  7. Take one 1/2 and place it on front of the tray.
  8. Ask the child how many pieces are here. (One 1/2). Say, “There is one.”
  9. Place a line over it: and write 1 over it.
  10. Replace the 1/2 back onto the tray.
  11. Repeat in this way for all of the fractions.
  12. Directress can remind the child that we place how many pieces are all together on the bottom and the piece we have taken out over the line.
  13. Do a Three Period Lesson for Numerator and Denominator.
  14. Then take out 2/3 or 7/9 or 2/5, etc and have the child write these fractions.
  15. Then read these with the child.

Labeling

  1. Have the child bring over the two trays of fractions.
  2. Take out all of the labels and place them in their corresponding piles in front of the tray.
  3. Have the child label each part of each fraction reading each label as he does so.
  4. Ask the child for the names of the numerator and denominator to check for understanding.

Control Of Error

The directress.

Points Of Interest


Purpose

To help the child gain a sensorial impression of fraction.
To introduce the concept and notation of fractions.
To introduce sensorial exploration of equivalency among fractions.
To introduce simple operations.

Variation

  1. Two children can work together by mixing all of the labels together and then labeling each piece of each fraction.
  2. The children who may need more work can play a game in pairs, one picking a slip with a fraction written on it and the other child pointing to it or taking it out of the tray.
