This lesson is an intro to numerical patterns (increasing & decreasing). There is a total of 18 slides consisting of I do, We do, You do. After finishing the slides, you will then pass out a penguin to each student where they will complete the numerical pattern given to them. I printed them, laminated them and had students used dry erase markers. You can also just print and have them use pencil. Once they are done, they can wipe it off and pass it to the next person.
