This week, we had learned on Number Operations and Basic Facts and also week 4 lecture topics which were Operation Sense and Computations. We do have our replacement class on Tuesday due to the Chinese New Year holidays. For number operations and basic facts, we learned on how to develop meanings for the operations of addition, subtraction, multiplication and division. Madam Lam teaches us on how to illustrate the children using models or concrete things in order to show the children how to add, minus, multiply and divide numbers.

Besides, we also had been exposed to the basic facts of addition which is involved two one-digit addends and their sum. The basic subtraction facts rely on the inverse relationship of addition and subtraction for their definition. Basic multiplication facts each involve two one-digit factors and their product. While basic division facts rely on the inverse relationship of multiplication and division.

Operation sense and computations involved the role of mental computation and computational estimation. This topic required us to calculate the numbers mentally and try to explain how we did it. The focus for these mental calculation activity is children find their own way and strategies and reflecting on what they are doing.

For our tutorial, we were divided into four groups and need to prepare one activity using cards and exchange the activity with the other groups so that they can play all the 4 activities. My group did a activity which was called addition Bingo. The leader draws a card and reads the addends on it. Each player covers the sum on his or her Bingo card. Not all sums are given on each card. Some sums are given more than once on a Bingo cards, but a player may cover only one answer for each pair of addends. The winner is the first person with 5 markers in a row.

For the next tutorial, we were divided into groups and complete the activity 1 and make a comment on the findings regarding to the activity.
