This product was used to to teach first grade students the concept of subtracting a double digit number from another double digit number.
It includes a week worth of activities that focus on the concept of being able to subtract two double digit numbers, along with finding the cookie thief!
the first day lesson starts out introducing/revisiting the concept of subtracting a single digit number from a double digit number.
The days that follow move into subtracting 10 from double digit numbers.... and then the end of the week is focused on subtracting a double digit number from another double digit number without regrouping.
This product includes lesson plans - I do, we do you do; and the materials to cover each day's lesson.
When I implemented this unit, I made the other teachers on my team the suspects, along with the principal and vice principals. In this product I have included the suspect pages I used but I also included the pages with no names/ or suspect pictures so you could add your own if you would like!!
