Here are the concepts that you may need a little extra help in:
Le "Diagramme à bandes doubles" (the Double Bar Graph):
L'estimation - "selon le premier chiffre" (first number) et
- "selon les nombres compatibles / nombres faciles (easy numbers, often like rounding)

Four ways to Represent Numbers
How we add and subtract in Grade 5:
SS1 - Design and construct different rectangles given either perimeter or area, or both (whole numbers) and draw conclusions.
What is Perimeter?
When finding the Perimeter of a rectangle or square, you can also use this formula:
(length + width) x 2 as this is the same as "the sum of the sides"
What is Perimeter?
When finding the Perimeter of a rectangle or square, you can also use this formula:
(length + width) x 2 as this is the same as "the sum of the sides"
What is Area?
N11 - Addition of Decimal Numbers:
Subtraction of Decimal Numbers:
N9: Associating equivalent fractions and decimals
N7: Fractions - concrete and pictorial representations; creating equivalent fractions; and comparing fractions
N7b: Use personal strategies to determine one or more equivalent fractions for a given fraction:
In this example, notice how each of the four rectangles are identical in size, but different in how they are divided in equal parts. This is a very important point when creating a "representation" of equivalent fractions.
N6: Dividing a 3-digit number by a 1-digit number:
N6a: Dividing a 3-digit number by a 1-digit number with a symbolic representation, using base ten blocks
N6a: Dividing a 2-digit number by a 1-digit number using "Base Ten Blocks" (including a symbolic representation, estimation, and verification)
N5c - Multiplication of a 2-digit number by a 2-digit number using the Expanded Form
(la forme décomposée / la forme développée), also called "using distributive properties":
(la forme décomposée / la forme développée), also called "using distributive properties":
N5a & N5b - Multiplication of a 2-digit number by a 2-digit number using the Area Model (Modèle aire):
- using the "simplified or quick area model" - in French it's called "Modèle aire simplifié" (on right only):
- illustrating symbolically (area model) with an array (matrice) and base ten blocks (blocs de base dix):
- illustrating symbolically (area model) with an array (matrice):
