Some of the Mistakes Made by Many of Us
1. Many of the kids didn’t support their work with mathematical thinking and ideas.
Example:
Incomplete answer: 24 books in total
Complete answer: There were 24 books in total because I was given information about shelves and the books on them. There were 3 shelves and each shelf held 8 books. I multiplied 3 times 8 and got an answer of 24.
2. Many of the kids only showed only one way of solving instead of two ways to solve.
Incomplete answer: 3 X 8 = 24
Complete answer: (two or more of these to support each other)
3 X 8 = 24
Shelf 1 ////////
Shelf 2 ////////
Shelf 3 ////////
8 + 8 + 8 = 24
8 x 3 = 24
24 / 8 = 3
24 / 3 = 8
X x 8 = 24 X = 3
