Grade 4 - Algebraic Reasoning Unit

4.4A

Add and subtract whole numbers and decimals to the hundredths place using the standard algorithm.

4.5A

Represent multi-step problems involving the four operations with whole numbers using strip diagrams and equations with a letter standing for the unknown quantity.
4.5B

Represent problems using an input-output table and numerical expressions to generate a number pattern that follows a given rule representing the relationship of the values in the resulting sequence and their position in the sequence.

The Algebraic Reasoning Unit involves developing an understanding of expressions and equations to answer questions such as:

How can you use equation(s) to represent this story problem? What do the variables in your equation(s) represent?
How does a table help to identify the relationship(s) between real-life paired numbers? Can you come up with a rule to describe this relationship? Explain.
How might an expression be used describe the relationships in your table? How can you use the expression to extend the number pattern in your table?
