Algebra is about recognizing the relationships that exist among qualities and operations. These relationships are a good springboard for the symbols that algebraic expressions represent. Students at a very young age can explore algebraic relationships. Here are a few tips to get you started:

1) Explore Properties & Relationships using Manipulatives

When multiplying, students can use the commutative property of a X b = b X a. Before introducing the equation, students may explore this with tiles while creating various arrays. For example, start with 24 counters. How can 24 be represented in two different ways?

Experimenting with manipulatives such as tiles or counters will lead to understanding and representing the operations with a formula. Another way to do this is with balance scales. This can happen as early as Kindergarten.

Choose linking cubes for this activity. Start with 10. You can add 5 and 5 on one side and then 3 and 7 on the other. Will they balance out? You can generate various situations using the number 10. From the visual representation, students can then see that 5 + 5 = 3 + 7. You can even place these equations at a math station and have the students explore them. 5 + 5 = a + 7.

2) Algebraic Reasoning Becomes Functional Thinking

Working with visual patterns allows young students to see the relationships between numbers. This can be accomplished through math read alouds. One of my "go to" read alouds is __Two of Everything__.

This story is a great way to talk about functions and function machines. Working with a function
machine allows students
to select input numbers that
are then transformed by a
particular rule to generate output
numbers (in this case doubling numbers). This task engages
them in thinking about the
relationship that holds true
for all input–output pairs.

Older students connect visual
representations with symbolic
representations, allowing them
to explore the properties of
functions (example, table of values, graphs....). Younger students can create an input-output chart.
