5th grade packet
Today the blue group revisited subtraction with regrouping, and took a pre-assessment for our next unit on multiplication and division.  4th grade Blue Group homework:  The students have subtraction classwork in their binder to work on tonight, or the "nine digits challenge" if they finished with the classwork and began this in class. 
Fourth grade math
The purple group learned a new game, Two-dice Sums, to think about probability--the chances that something will happen.  Students placed 11 pennies on a game board with the numbers 2-12, recorded where they put the pennies, then rolled two dice.  If they had a penny on the sum, they could remove the penny. The first person to remove all their pennies won, and kids recorded how many rolls it took to clear their pennies.  Students also finished their assessments from the data analysis unit, and took a pre-assessment for our upcoming unit on multiplication of large numbers and division.
