We had fun doing ‘hundreds’ of things this week.

Number Sentences from a picture
Grade ones have been working on making number sentences to match a given picture. This is proving to be challenging for many.
We have discussed how to make two reciprocal addition sentences by adding each group to the other – both ways – and getting a total. For subtraction they can also make two number sentences – one each for subtracting each group in turn from the total. With subtraction they need to start with all of the items i.e. the total (biggest) number.

100’s Day Activities
Students did hundreds of things last Thursday for our 💯s Day celebrations.
They made necklaces with ten groups of ten colours of Fruit Loops.
They made headbands with 20 stickers and counted by fives to one hundred.
On the crowns they drew ten different groups of ten shapes in different colours.
They enjoyed showing off their handiwork
We divided up 100 jelly beans in two ways - by colour and by 19 for the number of our students.
And then the jelly beans were eaten ...

100’s Day Collections!
Thank you for helping your children create such wonderful collections of 100 things!
100’s Day Posters
100’s Day!!!
We had a very busy day doing ‘hundreds’ of things – literally! After Calendar, where we officially moved into our 100th Day of school, we created Fruit Loop necklaces with 100 pieces of cereal on each string. Students counted 10 of one colour before adding it to their string. They did this ten times (alternating colours) to get to 100.
While awaiting their turn at the necklace station students worked on their crown headbands. On the crowns they were to chose ten different colours of felt markers and do ten groups of ten objects (dots, shapes, stars, etc.) to create 100 in total. These crowns were attached to headbands that they were to place 20 stickers on (in a pattern, hopefully) where they wrote the numbers to 100 by counting by fives.
What We KNOW or Think We Know …
We had a brainstorming session where the students talked with their partners and came up with things that they knew, or thought they knew, about bats. All answers were accepted. As we learn about bats we will confirm or debunk these thoughts and ideas.
Students then came up with a list of questions that they want to know about bats.
These will form the basis of our inquiry into bats. We are currently reading, “Zipping, Zapping, Zooming Bats”. So far students have learned that bats eat mosquitoes (so they won’t bite us) and help protect crops for farmers by eating grasshoppers, moths, and other bugs. The Little Brown Bat can eat 600 mosquitoes in one hour!
100’s Day!
Monday, February 19th was a busy day in our class! It was the 100th day that we have been in school.
Students worked with the number 100 in a variety of ways. This included: counting by ones, twos, fives, and tens up to 100. Students made headbands with 20 groups of tally marks (5 each). They counted Fruit Loops into groups of ten and put ten groups together on a string to make a necklace.
Students had worked on a 100 Day poster at home. They also worked on a booklet with all sorts of 100’s activities.
