This week in maths 3D has been exploring the concept of “rounding” and building their understanding by using a number line. The use of a number line helps students to visualise what tens or hundreds a number is CLOSEST to so as to “round” it appropriately.
The use of terms like “round up” and “round down” can confuse students. For example, the number 37 would round to 40 or they say it “rounds up”. The digit in the tens place is changed from 3 to 4 (rounds up). This misconception is what causes the problem when applied to rounding down. The number 32 should be rounded (down) to 30, but using the logic mentioned for rounding up, some students may look at the digit in the tens place and take it to the previous number, resulting in the incorrect value of 20. Asking questions such as: “What multiples of ten is 32 between and which is it closer to?” and developing the understanding of what the answer choices are before rounding can alleviate much of the misconception and confusion related to rounding.
To support at home you might like to ask your child questions such as, “What tens number would 63 round to? Why?”, “What hundreds number would 567 round to? Why?” or “If my number could be rounded to 40, what might my number be?” Ask your child what might happen to a number that is in the middle between two “tens” numbers or two “hundreds” numbers.
In uoi time, we revisited our list, from the start of the unit, of things around UNIS that we thought were simple machines. We marked those we are now more sure about, those that we now believe are definitely NOT and some we’re still wondering about. We also added some we didn’t realize actually were simple machines.
We have also begun designing our own creations that make life, work or play easier or more fun. We are excited to announce……….
We hope you can make it. To support the building of designs we are looking for: toilet roll tubes, small cardboard boxes (e.g. milk cartons, gift boxes), plastic bottle tops, ribbon.
October break: Saturday 5th October through Sunday 13th October
Grade 3 Innovation Fair, 2:45pm Friday 18th October
UN Day Monday October 21st
It has been an exciting time in uoi this week. We have been using our knowledge of the wheel and axle and attachments to build a car. In addition, we were challenged to see how far our car could travel after rolling down a ramp (inclined plane). Could we improve our initial model so that the car travelled further? We used our maths skills to measure and record the distance. Take a look at our Fast and Furious car challenge. Please ask us about our design: what was easy, what was hard, what did we change or modify?
On Tuesday we had a very exciting time Exploring Pulleys with Mr. Neal. We discovered that a pulley system can make lifting a heavy weight easier – and the more pulleys you use, the easier it gets!
This week we also had time with our K1C Buddies who wanted to compare our homes with theirs. They also wanted help to create some maps of how to get from their room to ours.
– Parent/Teacher /Student Conferences information: Monday, September 30th – no classes for students
Please send in toilet roll tubes, small cardboard boxes, plastic bottle tops & pieces of ribbon for our construction projects.
Have a lovely weekend!
As we missed a post last week, there’s LOTS to look at in this one. Following are links to folders of photos, plus a video made by Ms. Ngan
Moon Festival – masks and us.
Ms. Megan joined us for community time and taught us about how our brains work when we are learning something new and how to take care of our brain. The analogy of a field was used. Photos here of Ms. Megan’s visit.
The provocation at the start of our “How the World Works” unit of inquiry was a Marble Run. We had to get a marble across the room without pushing or dropping it; it had to move on its own. We could use anything we liked in the room. There was lots of design, try, fix, improve, try again, rebuild and try again and again and again!
Later we tried to build a “Wheel and Axle” – not as easy as we thought!
We decided that as glue is a form of plastic, we really shouldn’t be using it unless we have to so Mr. Neal showed us different ways to make attachments: Making different “attachments” so we don’t need to use glue!
At the end of this unit, students will be asked to design and build something that incorporates at least 2 Simple Machines and be able to explain the forces involved.
In maths we have been describing the ways we see numbers and patterns. How would see these dots and know there were 7 – without really counting them?
We saw them in lots of different ways:
We have been celebrating Peace Day and talking about what peace means to people. We read Quentin Blake’s “The Sailing Boat in the Sky”. Max and Martin even made a Peace Boat using their MakerSpace ideas.
Reminders & Notices:
Monday 30th October Conferences with child, parents and teacher.
Friday October the 18th October at 2:20 the last period of the day – mark your calendars! This will be a Showcase of our How the World Work Designs.
Have a lovely weekend.
Many thanks to all those who made the Back to School Night. It was great to meet so many parents. Please find below the extended presentation full of lots of useful links.
Students worked very collaboratively this week determining the meaning of the Learner Profiles and creating their own poster to explain and show them. Photos here.
- Moon Festival Thursday 12th September – students are encouraged to wear an Ao Dai
- No School for students Friday 13th – Professional Development day for teachers
This week 3D have started using Seesaw. They learnt how to log in – both through Google and using a QR code. How to check they were in the correct folder before working. How to add photos, use the microphone and the drawing tools. Please take a look at your child’s work and leave them a comment. Our final project on Seesaw this week was creating our own copy of 3D’s Classroom Agreements and annotating them. Students can complete this activity at home by going to app.seesaw.me The Classroom Agreements are:
- Do your best
- Be kind
- Be helpful
- Play and work with anyone
This afternoon the whole of Grade 3 got together for some fun community time and to practise listening skills. We definitely need more practice! However, ask your child if they can teach you the “Double This, Double That” activity.
Finally, 3D are SUPER excited that 5 of their classmates have been chosen to perform in the Grade 2-3 Musical, Aristocats. A huge “well done” to them and all who auditioned. Great risk taking!
Monday is a holiday.
Back to School Night, Thursday 5th September (see TinTuc for details) – hope to meet lots of you there.
In addition to getting to know each other a little better, 3D have also been spending time with other grade 3 classes. Here they are having fun playing Blind Drawing with 3C and doing some shared reading with them also.
Below is 3D’s full class schedule. Although maths, uoi (unit of inquiry) and English times are all marked, we often use a transdisciplinary approach to teaching and learning meaning that these subjects can be merged.
Next week we will welcome a new student to 3D: Mei Kanno.
Please let both Miss Julia and Ms. Ngan know whenever there are any changes in your child’s “end of day” routine i.e. if they are being collected by a different person or not taking their usual school bus that day. If there is a change in the usual Bus routine, please also inform Mr. Lai the Transport Manager.
Hat, Water Bottle & a healthy Snack are needed every day. Labelled hats and water bottles are a BIG help!
Welcome to 3D, 2019-20
Today we had a great time with all of G3 playing some community games. See here for some photos and videos.
Please see below 3D’s schedule of Specialist times. A hard copy of this has been sent home with your child today.
We are excited to announce auditions for the Grade 2/3 musical: Aristocats.
Here is a brief summary of the story:
Sign-up sheets for auditions are outside 3D. A sample piece of script to practice can be collected from Miss Julia in 3D (B9, 106).
*Photo day for 3D students will be the 29th of August
*Back to school night will be early September
Have a restful weekend!
