We were so excited to receive a big envelope in the mail. Inside were our first replies from our pen friends who belong to 2Gold. The letters were full of answers to our questions, some interesting information about their learning and some questions for us to answer. The Grade Twos from North Reservoir did a great job with their letters and we got busy writing back to them. We hope to have our letters in the mail before we go on holidays.
In Week Ten our focus in maths is MONEY. We are using the strategies we have been exploring for place value, addition & subtraction to solve problems using MONEY. Today we discovered two new mathematical symbols: < & >… greater than & less than.
When you write one of these symbols between two numbers you are comparing the value. The closed end points to the smaller number and the other end opens up to the bigger number.
45 > 12 is read as 45 is greater than 12
34 < 96 is read as 34 is less than 96
We used these symbols to compare sets of coins…
To help remember which symbol is which we tried to visualise fish. The fish always wants to eat the bigger number!
I wonder how many different ways you can make $2. I can think of 4 ways straight away…
Over the last few weeks we have been exploring strategies to help us solve problems involving subtraction. We have discovered some generalisations about subtraction and some strategies that help us work out facts more quickly:
Subtracting 0 from a number gets the same number.
Subtracting 1 from a number gets the number that is one less.
Subtracting the same number gets 0. 4-4=0; 6-6=0; etc.
“Think Addition” – what number can you add to the number you are subtracting to get the starting number. For example, 9-4=__. What number can you add to 4 to get 9.
When subtracting 9, think subtract 10 and then add one on
Count backwards. We have a number line in the back of the room or students can make their own on their paper. For the problem 13-5=___, start on 13 and count back 5.
We have also used a number chart to help count back bigger numbers. Some students have explored using an empty number line and this week we are going to try using a strategy called partitioning.
What strategy do you like to help solve subtraction equations?
Here are some websites that can help you practice getting quicker at recalling subtraction facts:
In the story of creation from the book of Genesis it is written that: “God said, “Let the water teem with living creatures, and let birds fly above the earth across the vault of the sky.” 21 So God created the great creatures of the sea and every living thing with which the water teems and that moves about in it, according to their kinds, and every winged bird according to its kind. And God saw that it was good. 22 God blessed them and said, “Be fruitful and increase in number and fill the water in the seas, and let the birds increase on the earth.” 23 And there was evening, and there was morning —the fifth day.”
After making the people, God gave them the special job to “rule over the fish in the sea and the birds in the sky, over the livestock and all the wild animals, and over all the creatures that move along the ground.”
This special job is called being a steward and this term as we have learnt about life cycles and habitats so that we can do this job better.
June 8th was World Oceans Day, the day for the global community to celebrate and take action for our shared ocean. One of the greatest threats to the ocean is litter – especially of the plastic kind.
This week we have explored how the litter we drop at school can end up in the waterways around Greensborough and even eventually into the ocean. Each year a huge amount of plastic eventually makes it into coastal waters and harms ocean life. Many animals such as seabirds, sea turtles, dolphins, and whales die every year from plastic entanglement or starvation because they fill up their stomachs on plastic they mistake for food.
Here are some ideas we can all think about help us be better stewards of the water God created for us all.
Reduce plastic use:
Plastic water bottles. Use a reusable water bottle
Plastic bags. People use nearly 1 trillion plastic bags each year, and unfortunately, many of those end up ingested by sea turtles that mistake plastic for jellyfish. Bring your brain food to school in reusable containers rather than plastic bags.
Bin it properly. Don’t drop your rubbish on the ground and when it goes in the bin make sure the lid always goes back on.
To help celebrate World Ocean Day we created some art works. Next week we will be writing an exposition to help raise awareness about the litter problem we are all part of.
What types of things does your family do to reduce, recycle and reuse?
What ideas do you have that can help us to be better stewards of creation?
