Good-bye party
Students each made a page for a special appreciations book for Calista today, and presented it to her at a party at the end of the day. Calista's mom brought two enormous hamburger cakes for us to wish Calista Bon Voyage. We all wished her best of luck on her adventure to Argentina.

Fourth grade math
Purple group:
The purple group started with a mental math warm up. These activities are helpful to review different subjects, including time-telling and today, metric measurement. Mia shared that the way she remembers that there are 100 centimeters in a meter is to think of 100 cents in a dollar. Ronan pointed out that it can be hard to think of 100 as a 10, in the question: what is the nearest ten to 98? But 100 is a multiple of 10.

We also spent time breaking double digit numbers into a sum of a multiple of ten plus a unit, to make it easier to multiply. Students practiced this, then worked on their JUMP math packets. We also started talking about how to break numbers in ways that make it easier to double them.

4th Grade Blue Group: Today students practiced solving division problems with remainders mentally by skip counting. We reviewed multiplying with powers of ten working up to problems such as 20 x 13, and solving word problems with multiplication.
