We started to work on the Subtraction Memorization sequence after finishing up the last of the Addition Charts. D preferred to write and fill up the last Addition Chart. I did cross question a few sums to make sure D was just not following the pattern to fill up the chart and she did perfectly fine!
So I presented the Subtraction Strip board to her.
She caught on and started to fill in the booklet on Subtraction tables. She figured out that since she knows the sums, she did not have to use the board!
There were a few that she was not sure, so she only used the blue strips to cover the squares that she did not need to figure out the answers! So much for buying this set hoping it would get a lot of use! So now I am off to printing the Subtraction Equation slips for her to use. I don't think we are going to stay on this for long, so I might have to get her to work on skip counting, so we can start working on the Multiplication Board simultaneously.
