100s Day Happenings

Our collections upon arrival and later on the bulletin board after school.


Some items were too big / heavy for the bulletin board.

Some of the hundreds of things we did today:

Fruit Loop necklace making – ten groups of ten.


 

Making head bands and crowns:

Sorting and counting 100 jelly beans by colour (pink, red, and white) and Smarties. This was done by the Grade 2’s.





We were very lucky to have some wonderful helpers this morning. Thank you to Dana (no photo), along with two of my former students, Maya and Lyka. They really enjoyed being in the class again after 13 years and the students really enjoyed meeting them.

It was a very full, busy, and fun day ☺️

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!!!

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!
