Over the past 5 weeks, In math class, we continued learning the 5A Primary Math textbook and workbook (a Singapore math book) which we had just finished the 4B book before the break. We had finished 3 units of the book and started learning unit 4. We learned about the distribution of property, factor, learn about different ways of finding prime factorization and how to write using exponent. we also learned the order of operation, estimating the value and get a little introduction to algebra. Not only this, we learned about fraction, how to evaluate the expression such as addition, subtraction, multiplication, and division, included simplification. We usually work on exercises in groups because the teacher wants us to collaborate with each other to solve the problems and explain each other because math is one of the difficult subjects. Besides learning from the book, the teacher also assigned us to do the assignment in Khan Academy which is a website for learning several subjects such as math, science, Khmer and more. The purpose of doing this is to learn more and get more practice and if we struggle, we can always watch the video and learn from this website. When there is time left in class, we usually do some online activities such as puzzle, sudoku, and other online games that related to math or the lessons that we had learned. So, these are what we had learned during this past 5 weeks and I enjoyed learning math so much and it is my most beloved subject.
