Mr. Donnellon's Classroom News
Odds and Ends
- It is hard to believe that another card marking has come to an end. I am still missing a couple of report card envelopes. Please remember, after reviewing the report card and other reports which may be included in your child's report card envelope, keep the contents of the envelope and then return ONLY the envelope signed under second card marking period.
- Tuesday, February 14th will be our classroom celebration and Valentines exchange from 2:15-3:15. If sending in an edible treat with your child's valentine, please make sure that it is nut free and processed in a nut free factory. Any treats which do not meet this requirement will be held at school and returned at the end of the day to take home. Thank you for taking the time to consider those students with nut allergies.
- No school on Monday, February 20 or Tuesday, February 21.
- Students have taken the Winter NWEA-Map test in the areas of Mathematics, Reading, and Language. This is one of the assessment screening tools Royal Oak uses to track student progress. Results of this test will be sent home to parents when available for print.
- If your student hasn't signed up for Science Olympiad, please encourage him/her to consider this event. It is a great opportunity for students to enjoy working with the scientific process skills in a friendly and fun after school atmosphere.
We have finished up Measurement, Time, and Graphs and have moved into our fourth unit, Multi-digit Addition and Subtraction. In this unit we have studied three research based methods for multi-digit addition: the common algorithm New Groups Above, plus two methods found to be effective at this grade level, New Groups Below and Show All Totals. These methods are introduced to help students see and discuss core mathematical ideas about addition and subtraction.
To subtract multi-digit numbers, students are taught to ungroup all the places before subtracting. Research has found this approach reduces errors and helps develop conceptual understanding of multi-digit subtraction.
With both multi-digit addition and subtraction, students will be taught to provide "proof drawings" to show their thinking when needed.
