For my grade 2, I will be working with addition up to 20. For example 15 + 2

Unconsciously Incompetent:

Students will use manipulative or count 15 by 1’s and then add the 2 (again the whole concept skip counting by 1)

Consciously Incompetent:

Some students might skip count by 5’s to 15 , then add the 2

Consciously Competent:

Students will start with the biggest number 15 and add 2

Unconsciously Competent:

They will just say the answer, but cannot represent their thinking in anyway!

Consciously Masterful:

Students will understand that we start with the biggest number 15 and then add 2

They can also represent their thinking using a number line or base 10 blocks to represent the 10 + 5 + 2
