Contents
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
- Have the child bring over the first tray of fractions.
- Take out the whole circle. Directress tells the child “This is a whole.”
- Place the whole in front of the tray.
- Directress takes out one of the group of 2 and say, “This is a 1/2”.
- Place it in front of the tray.
- Repeat in this way up to the group of 5. (1/2)
- Directress does a Three-Period Lesson for the group of 1, group of 2, group of 3, group of 4, and group of 5.
- Once the child is familiar with this tray, do the same for the second tray.
Writing
- When the child knows the names, begin with the two trays.
- Directress points to a few fractions and ask the child what it is.
- This will serve as your check to see if the child knows the names.
- Tell the child that you will show him how to write fractions.
- Point to the group of 2. Ask the child how many pieces there are. (2) .
- Directress says, “Yes, there are two pieces, so I will write a 2.”
- Take one 1/2 and place it on front of the tray.
- Ask the child how many pieces are here. (One 1/2). Say, “There is one.”
- Place a line over it: and write 1 over it.
- Replace the 1/2 back onto the tray.
- Repeat in this way for all of the fractions.
- 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.
- Do a Three Period Lesson for Numerator and Denominator.
- Then take out 2/3 or 7/9 or 2/5, etc and have the child write these fractions.
- Then read these with the child.
Labeling
- Have the child bring over the two trays of fractions.
- Take out all of the labels and place them in their corresponding piles in front of the tray.
- Have the child label each part of each fraction reading each label as he does so.
- 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
- Two children can work together by mixing all of the labels together and then labeling each piece of each fraction.
- 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.
