Understanding multiplication and division concepts
1. My Thinking Sheet Name: Date:
How many ways can you
represent this photo?
N3.3 Demonstrate understanding of multiplication to 5 × 5 and the corresponding division statements including:
• representing and explaining using repeated addition or subtraction, equal grouping, and arrays
• creating and solving situational questions
• modeling processes using concrete, physical, and visual representations, and recording the process symbolically
• relating multiplication and division.
N4.4 Demonstrate an understanding of multiplication of whole numbers (2- or 3-digit by 1 - digit) by:
• modeling the distributive property
• using personal strategies for multiplication, with and without concrete materials
• using arrays to represent multiplication
• connecting concrete representations to symbolic representations
• estimating products
• solving problems.
N4.5 Demonstrate an understanding of division of whole numbers (1-digit divisor to 2-digit dividend) by:
• using personal strategies for dividing, with and without concrete materials
• estimating quotients
• explaining the results of dividing by 1
• solving problems involving division of whole numbers
• relating division to multiplication.

3. Turn over two cards.
Record the process using repeat
addition and symbolically (Multiply them together).
I think 7 groups of 4 OR 4 groups
of 7.

4. Turn over two cards.
Record the process using repeat
addition and symbolically (Multiply them together).
The factors are 7 and 4.
The product is the total when you
multiply or add 7 groups of 4.
I think 7 groups of 4 OR 4 groups
of 7.
4+4+4+4+4+4+4=
7x4=28
7+7+7+7= 4x7=28

His trainer has 20 peanuts.
If he gives Jumbo 5 peanuts each day, how many days will the peanuts last?
