How do you introduce an array to a student?
To first teach arrays or to help your lower students, I really recommend using cubes. The cubes that snap together really show WHAT repeated addition actually is because they’re connected in sets. The cubes will really help them see that 3 x 4 is 4 repeated 3 times.
