More learning in sound and light today. We spent lots of time in the dark today!
We learned that light travels in a straight line. We also learned that light can be stopped (ABSORBED) by some materials. I.e. the bat symbol
We also learned that light can reflect off shiny surfaces and pass through some surfaces.
We used prisms to learn that light is made up of many colours!
Over the last little while in math we have been working on multiplication. We first worked on strategies for multiplying single digits by single digits (e.g. 7×9). Last week, we worked a lot on various strategies for multiplying a 2-digit number by a 1-digit number (e.g. 34 x 6).
Many students today have not mastered memorizing multiplication facts, so until they do, they need some strategies to help.
We learned about many strategies including, but not limited to:
Multiplying is really repeated addition (3×6 is 6+6+6)
Multiplying is skip counting (6, 12, 18)
Stacking (what most of our moms and dads do when multiplying)
Decomposing (34 can be 30 AND 4)
Friendly TENS numbers (take away the zero, add the zero when multiplying by numbers like 40)
NEAR friendly numbers (e.g. when multiplying 39 x 7, do 40 x 7, then subtract one group of 7)
Doubling (if multiplying by 4, you can multiply by 2 first, then double it)
Finger trick for multiplying by 9
Today we began talking about division. We looked at this picture first to help us understand WHAT division is and how it is connected to multiplication.
You can help your child at home by practicing their multiplication facts until they know them by heart.
Also, help them see that division is about equal groups. We have 20 pieces of potato for dinner. If we give each of our 4 family members an equal amount, how many pieces will each person get?
On Friday we experimented with making sound and tried to answer the following four questions:
1) How is sound produced?
2) How are low and high sounds made?
3) How does the shape and material of an object affect the sound it produces?
4) In what ways does sound affect our life?
At the end of the unit, we will revisit these questions.
Here’s what our room sounded like. YIKES!!!
Today we learned that sound is vibrations and that you can hear, feel, and even, see sound!
We learned new vocabulary such as vocal cords, sound waves, and molecules.
Great job by Anzik, Manar, Mila, and Quinn on their patterning exit cards earlier this month. Exit cards are a tool we use occasionally to check for understanding or as a quick assessment. Sometimes a few of these are better than bogging students down with a big test
Today students brought their habitat projects home. Please look for the marking rubric that is attached to their report.
It took us many days to get through all 27 presentations and me many hours to mark them all, but we are finally done! It was well worth the effort. Many of our students clearly enjoyed the hands on learning opportunity; applying what they learned about their animals habitat. As well, we learned a lot from our first big research assignment. For example, the importance of giving credit to your sources, putting ideas into your own words, gathering lots of information from multiple sources, and putting your new knowledge together in well written and organized paragraphs. Here are a few highlights:
Both Manar and Ayan did a great job taking notes when researching. Pulling just the key ideas out of a text to make point form notes is an important skill.
Adnan wrote wonderful paragraphs on the positive and negative effects that humans have on the Timber Rattlesnake. I also thought it was a nice added touch that he gave his family credit when listing his sources.
Joel constructed some well informed paragraphs, did a good job incorporating our learning about eco passages from class, and had a nicely labeled food chain.
Elora showed us how easy oral presentations can be when you do your work on Google slides.
(Waiting for shared permission so I can share her work with you here…stayed tuned to edits on this post)
And of course, all of our many amazing dioramas…It was great to see how many students remembered to show all the parts of a habitat: space, water, shelter, and a relationship with specific other animals and plants. Well done everyone. I’m sorry if I missed any. I tried to get everyone’s. If I missed yours here, let me know or send me a picture and I’ll add it in.
