In this Investigation, the students experienced adding and subtracting positive and negative rational numbers, by modeling real-world situations using different models. The most non-intuitive computation was subtracting negative numbers. For examples : why 4 – (-2) = 6 ?
Ask your child to use the chip board model ( red & black chips ) explaining why it does make sense.
We also strength our skills using our class favorite activity – Kahoot.
A few minutes before the end of class, I gave the students a fun challenge. Guess what : They couldn’t leave the class without solving it.
Since the students like interactive activities, we have decided that every student will prepare an activity once a week. The activity will include planning, designing and has to be related to the current material or math in general.
Today, we had the first activity that was related to our first mathematical investigation – The Family Of Polygons.
I was very impressed. He did an amazing job!
Can’t wait for the next one.
During our first investigation that contained five different problems, we focused on understanding the properties of polygons that affect their shape, special relationship among angles and the properties needed to construct polygons. Summarizing the investigation, the students had to draw geometric shapes, subject to constraints, using a ruler and protractor.
MJDS’s Community,
I am very excited to start the school year as a math teacher in MJDS. This year we are going to develop our math skills, learning strategies and creative thinking in a pleasant atmosphere. We will learn together in a collaborative and experimental environment in order to achieve our goals.
About me :
I taught math in junior high, high school and practical engineering college. I’m holding a bachelor’s degree in computer science and a master degree in mathematics education.
GOOD LUCK !
