Leek or green onion cut in 5

Take 2 leeks of similar size and shape and a baby plastic spoon. Choose the thickest leeks for this activity. Cut one leek into 5 equal parts either lengthwise and make them look the same (or almost the same). Say we cut the leek into five equal parts. Each part is the same as the other ones. Take 1 cut piece. Say this is one fifth of the leek. Let us put it right here. Put one fifth of the leek in front of the baby. Say: let us pretend that this spoon is out imaginary line. We will put it under the fifth of the vegetable. Put the spoon below the piece of the leek. Take another leek and also cut into five equal pieces. Say now this is the whole leek made of five pieces. If we put the five pieces together, they will be one whole leek. We will put this cut into five pieces leek beneath the imaginary line – our spoon. Put all the five pieces of the second leek under the spoon. Point to the one fifth of the leek and say: one (point to the 5 pieces below) fifth of the leek! Point several times to the one fifth and the five pieces below and name them. Take another fifth piece. Say I will put it next to the first one fifth. Take it and put it above the spoon and next to the first cut piece. Say: now we have got two fifths of the leek up here! Point to the pieces and start counting: one, two. Point to the 2 pieces and say 2! Point to the five pieces below the spoon and say fifth! 2/5th!
