Multiplication

Number lines can be an engaging, colorful, versatile strategy for teaching number sequence, addition, subtraction, multiplication, division, and negative numbers. 

The Pros: By introducing number lines, students can visualize multiplication problems and build a great overall understanding of the multiplication operation in mathematics. This method can also simplify concepts such as multiplication and division, making these operations easier to understand. This strategy can also teach more advanced concepts such as fractions and decimals. 

The Cons: Students can easily misinterpret number lines or spaces in a number line, resulting in wrong results or discouragement in using this strategy. 

By introducing multiplication with repeated addition, students can gradually begin developing multiplication skills. 

The Pros: Repeated addition can simplify concepts, specifically multiplication. This strategy also strengthens addition skills. 

The Cons: Students can become too comfortable or reliant on solving multiplication problems using repeated addition, making it more challenging to mentally compute or practice other strategies for solving multiplication problems.
