Math is always been my favorite class. In this round, we received a new workbook which is 5B. So far, I’ve been learning about the Decimal chapter, including, converting from fraction to decimal, from decimal to fraction, round the decimal, estimate the value and last the four operations which are addition, subtraction, multiplication, and division. Besides that, we took a lesson on the binary number as well because it related to decimal. I’ve known about the binary number a little bit before as the teacher had introduced us since the first year at Liger. We did some group activities about this lesson and also played a game about it which was so fun. No matter we received a new book, started a new round, but we still did exercises in a group and besides that, we did some old and new group activities as usual. The reason is that as you all know that collaboration and teamwork is the important skill of our future. I think that’s all we’ve learned in math class this round, and I feel like this round seems too short as we didn’t get to learned much lessons.
