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
- Directress asks the child to bring over the first tray of fractions.
- Tell the child that "a fraction is dividing a whole into equal parts".
- Directress takes out the first circle and place it in front on the tray.
- Take out 1/2 and place it in front of the tray.
- Take out 1/3 and place it in front of the tray.
- Show the child how to carefully replace each fraction back into its spot.
- Do this for 1/4, and 1/5. Have the child replace each one back into its spot.
- Repeat a few times, mixing up the parts and having the child replace them in their correct spot.
- Once the child is comfortable with the first tray, have the child replace it back on the shelf and take out the second tray.
- Have the child explore this tray as with the first tray.
- Once the child is familiar with the second tray, use the two trays and repeat as above.
