Reflection: Diverse Entry Points How Many On My Plate? (Subtraction) - Section 3: Station Time


It is important to know your students and how an activity can be adjusted to meet their needs (both high or low).  In the Adapting For Understanding resource, I allowed a student to use the ten frame cards instead of the cubes.  I switched to cubes (mid unit) to see if the students had the flexibility in their thinking to apply the concept to a different unit.  This student still needed the structure of the 10 frame in order to complete the activity.  There is a photo in the section resource of her using the 10 frames. 

I also adapted this game to challenge a student with very sound Number and Operation Skills.  I gave him a packet of blank addition and subtraction What's On My Plate? recording sheets, a set of place value dice, and a spinner.  He would first spin to decide how much would be added or subtracted each time.  Then he would roll the dice and write the 4 digit number as the starting number.  Then he would add or subtract the number spun for each day.  There is a video that models this in the section resource as well as the blank recording sheets.
