Week of September 15-19

In 5th grade, we began our unit on probability.  We did some experiments involving coin tosses and picking colored cubes out of a bag, and we discussed what it means for outcomes to be equally likely.  We realized that equally likely does not always mean that the probability equals one half.  If there are 8 different colored cubes in a bag, the likelihood of picking each one is 1/8.
HW: p. 7 and 9 in the mathematician's journal (Remember to use the rubric to make sure your writing is the best it can be!)

In 4th grade, we started our Algebra unit by playing some guessing games involving mystery numbers.  Through these games, we learned the meaning of the term variable. We also learned the difference between expressions and equations and how these differences affect the definition of a variable.
HW: p. 3 and 5 in the mathematician's journal (Remember to use the rubric to make sure your writing is the best it can be!)

In 3rd grade, we talked about the importance of accuracy when taking measurements.  We learned how to convert millimeters to centimeters and measured various items around the classroom.  We discussed how different tools are appropriate for different types of measurement.
HW: complete p. 5 in the mathematician's journal.  List 8 more body parts to measure, decide what tool would work best, and explain the steps you would take to measure that body part.
