I love our transportation math units! My kids are having so much fun with them, and are really learning a lot! Here is the center called Transporting 10, where the student has to figure out the missing number that makes 10. I differentiated for this student by giving her unifix cubes as “cars”. I told them that the Car Carriers can’t leave the station until they are full, and it’s your job to figure out how many more cars they need. As you can see by the erasing she was having a hard time, that’s when I provided her with manipulatives to solve the problem. This item is for sale in my TPT store in my Transportation Unit.
