Cucumber cut into 4

Take 2 cucumbers of similar size and shape and a baby plastic spoon. Choose the thickest cucumbers for this activity. Cut one cucumber into 4 equal parts either lengthwise and make them look the same (or almost the same). Say we cut the cucumber into four equal parts. Each part is the same as the other ones. Take 1 cut piece. Say this is one fourth of the cucumber. Let us put it right here. Put one fourth of the cucumber in front of the baby. Say: let us pretend that this spoon is out imaginary line. We will put it under the fourth of the vegetable. Put the spoon below the piece of the cucumber. Take another cucumber and also cut into four equal pieces. Say now this is the whole cucumber made of four pieces. If we put the four pieces together, they will be one whole cucumber. We will put this cut into four pieces cucumber beneath the imaginary line – our spoon. Put all the four pieces of the second cucumber under the spoon. Point to the one fourth of the cucumber and say: one (point to the 4 pieces below) fourth of the cucumber! Point several times to the one fourth and the four pieces below and name them. Take another fourth piece. Say I will put it next to the first one fourth. Take it and put it above the spoon and next to the first cut piece. Say: now we have got two fourths of the cucumber up here! Point to the pieces and start counting: one, two. Point to the 2 pieces and say 2! Point to the four pieces below the spoon and say fourth! 2/4th!
