Jumping January News for Mrs. Hedberg’s Class
Math:
We have just begun Subtracting Two-Digit Numbers. Students will be learning various models to subtract two-and one-digit number, some traditional and some not. Students will draw on prior knowledge of number sense and place value. There is more than one way to subtract two-digit numbers. For example they have been breaking apart numbers using place value: Find 52-14: (50+2)
-(10+4)
______
Since they can not subtract 4 from 2 in the set of whole numbers, they need to regroup. The traditional algorithm for subtraction is difficult for most children to master. Please when working with your child at home ask them to explain how they need to regroup 1 ten as 10 ones, if necessary. Be sure they indicate this regrouping in the algorithm. During this unit students will learn how to use addition to check subtraction. This reinforces the inverse relationship between addition and subtraction.
Character: This month our virtues are Friendliness and Cooperation. Students will be making a friendship quilt and will have many opportunities to work in cooperative learning groups throughout the rest of the year.
I would like to say thank you for all the cards, small gifts, and goodies that came in over the holidays. I usually write personal thank you notes unfortunately, I misplaced my thank you list so please forgive me for the generic thank you!!
Sincerely, Mrs. Hedberg
