A very tricky math problem!

This morning we worked on our centers and then we spent some time practicing our songs for the assembly. We are trying to sing them without the lyrics and we are trying to use louder singing voices. After we finished practicing Jordan from room 1 shared some pictures from her holiday.

After recess we did word work. Then it was time for math. We are working on solving our final problem in treasure math. The treasure has arrived and we need to figure out how much we have in total and how many pieces each person can have.  Here's the challenge we are working on:

1. We have 288 gold coins and 84 chocolate coins. How much do we have all together?
2. We have 47 students. How many gold coins can each student have? How many chocolate coins can each student have?

To figure out the first question we have talked about representing the numbers as groups of 10 and then counting by 10's to add them all up.  We figured out that we would have 8 leftovers from 288 that couldn't be made into a group of 10 and 4 leftovers from 84 that couldn't be made into a group of 10. We have to remember to add these leftovers back in after we count up all the 10's.

To figure out the second question we are using an estimating strategy. We talked about the idea that 47 is pretty close to 50 and that 50 would be a lot easier to work with.  Then we started pretending to hand out the coins like this:
- To give everyone 1 gold coin we would need 50 coin.
- To give everyone 2 gold coins we would need 100 (50+50) coins.
etc.
We need to follow this pattern until we don't have enough coins to keep giving them out.

After lunch we worked on our dioramas. Many of us have finished our landscapes and buildings and are now moving on to adding the animals using plasticine. Before we were allowed to move on we had to prove to Ms. Boyer or a partner that we had added all the pieces we had planned by showing them our diorama and our planning page.

Swimming forms should have arrived home yesterday. Please try to bring them back as soon as possible and remember to pay the fees online. We are looking for volunteers to help us each day. Dads or grandpas are especially helpful as we need to have a male supervisor in the boys change room. If you are able to help please email Ms. Boyer. 

The helper tomorrow is: Ezra
