I found some smarties and sweethearts roll candies leftover from halloween (candy always makes activites high interest). I took some out, leaving 10 pieces of candy in each roll.
I gave Joshua a problem to solve, such as 52 - 5.
We counted out 52, using our tens and ones. Then I asked him how we were going to take away 5 ones when we only had 2. He figured out that we would have to unwrap a roll of 10, so we did. I asked him how many 10s we had now, and how many ones. Then he took away the 5 ones, and we counted again.
We did that a few times with different problems, and then I showed him how we write it out when we're doing it on paper, and if we wanted to do it without manipulatives.
|Here comes Nathan, trying to help him subtract some candy|
He picked it up pretty quickly, so I'd say it was a success.
