Write 3 page essay on the topic Math and the paraprofessional teaching fractions.
As a teacher, I need to address all the three models in well-designed instructional activities so that Bonnie and Emanuel can develop a rich concept of fractions, which they can use to make sense of measurement, numbers, and operations.
To give them the concept of 1/2, I will fold the red sheet into half and will ask them how much reds would be required to cover the yellow part completely. Like this, they will understand that two reds would be required to cover the yellow means one red would be required to cover 1/2 of the yellow sheet.
After this, to make them aware with the idea of 1/4, with the help of my students I will fold the blue sheet twice to create fourths. Leaving the paper folded, I will ask the students about the number of blue that would be using to cover the yellow sheet. In this way, they will come to know that four blues would be required to cover the yellow means that each part of the blue is 1/4 of the yellow.
For this model, we would be using a linking cube train. We will join the four cubes of the train together. at one end put the signboard of zero and at the other use the signboard written ‘one’ on it. Then to give them the concept of 1/4, I will put the board with question mark after the first cube. Then I will ask them about the number of cubes that are dividing the train. As the answer would be four, likewise I will try to explain them that the whole train is divided into four parts and one cube of the train represents 1/4 of the train.
With the same concept, in order to give them the idea of 1/2, I will make the train of two cubes and will put the question mark signboard after the first cube. In this way, I will tell them that since the train is divided into two halves. Therefore, in denominator, we will write the total division that is two and in numerator, we will write the block number that is before
