In Prep class we learned about subtraction using measurement. In the classroom, we poured seven cups of water into a bowl then we poured out two cups of water out of the bowl. Students watched the teacher measuring the water left in the bowl. All students did the experiment individually in front of the classroom under the teachers' supervision.
At different times, we went to the sandpit outside. Here students did the same experiment of measurement using sand. First they filled a bowl with five cups of sand then they poured out three cups of sand. They proved that there were four cups of sand left in the bowl. Students did this experiment individually in the sandpit under the teachers' supervision.
In Math, students say seven minus three equals four. Now Prep students are excited to learn subtraction.
