50th Day of School!

Today was the 50th day of school.  Each 10th day of school (20th, 30th, 40th, etc.) Zero the Hero comes (during the night, we think) to leave a special treat (usually shaped like a 0) for the boys and girls.  He somehow manages to get onto the Smartboard and leave a message too!  Today he left chocolate chips - 50 for each student.
We used the chocolate chips to do some counting - forwards and backwards.  We also did some problem solving to go with our current math outcome (ways to show numbers in equal groups).  Some very quick-thinking children discovered that we could make 5 equal groups of 10, 10 equal groups of 5 and 25 equal groups of 2!  Here are a few pictures:

Students counted 50 chocolate chips and placed them on their 50 chart.

We used the Smartboard to help us think about how we could show 50 in equal groups.

Students with their 50 charts and yummy chocolate chips!

Everyone was anxious to do some eating after the pictures were taken!  Students had to find certain numbers on their chart before they could eat the chocolate chips.
