Happy Star Wars Day!! This week
we are reading “Lost City: The Disovery
of Machu Picchu” by Ted Lewin. Next
week we will be taking the end of year PARCC tests, though we still have much
work to do before the real end of the year! In preparation for next week’s
testing, we will focus on some math vocabulary words this week. It would be helpful if you will reinforce the
meaning of these words at home with your child. These words will replace our
regular writing and spelling homework this week. Each night the students should
create a math 4-square (they know how to do this) for three of the words. Let’s
have a great week!
