Happy New Year families!
We will be wrapping up the Addition and Subtraction unit in a few days and beginning our Multiplying and Dividing unit. With that, comes the practice of new mental math facts (see Mental Math Link)
* I will be sending home a review sheet with our strategies and examples used in class, as well as posting a photo here. I will also send home a "Extra Practice" review booklet that is OPTIONAL. Do as much of it as needed, when you can. I do not mean to add to your busy plates; these work booklets were requested by many at Parent-Teacher and it is easier (between Mrs. Sanford and myself) to send it home with ALL students. They are differentiated in that the easier grade 3 work is in the front, with the more challenging grade 4 work is at the back (and labelled as such.)*
MULTIPLICATION:
What do we need to know?
Grade 3: Students are "expected to demonstrate an understanding of the multiplication facts to 5x5." In other words, this is considered an introduction for the grade 3's.
Grade 4: Students DO need to have quick fact recall up to 9x9.
Both Grades:
DIVISION:
What do we need to know?
Grade 3: Students are "expected to demonstrate an understanding of division related to multiplication facts up to 5x5". This is also considered an introduction; students are not expected to have quick recall of all the facts, though they should be practiced at school and at home.
Grade 4: Students will be "expected to demonstrate an understanding of division to solve problems using personal strategies," and estimate what the answer will be, with related facts up to 9x9. (One-digit divisors and up to two-digit dividend.)

Grade 4: Students DO need to have quick fact recall up to 9x9.
Both Grades:
- represent and explain multiplication using equal grouping and arrays.
- creating and solving problems in real-life context that involves multiplication.
- modeling multiplication using manipulatives and recording what they did symbolically on paper.
- Relate multiplication to repeated addition.
- Relate multiplication to division.

Both Grades:
- Represent and explain dividing using equal sharing and grouping.
- create and solve problems in real-life context, involving equal sharing and grouping.
- model equal sharing and grouping using manipulatives, and record what they did symbolically on paper.
- relate division to repeated subtraction.
- relate division to multiplication facts.
