Lots of things here to get kids adding and subtracting with the robots!
Start off with a 10 page slide show---use it one day for adding and the next day for subtracting. Follow each lesson up with a center activity with 20 cards. There is an addition and a subtraction center student answer sheet. You make one set of 20 robot cards, and you use them in two different ways!
I have also included three worksheets. One worksheet is all addition and one is all subtraction. Then there is one with addition and subtraction both. That one will make a great assessment.
Kids love robots so you can use this product about anytime! But it works great at Valentine's Day.
