Think addition to subtract was the concept covered in today's lesson. Gracyn worked on problems in which she used an addition fact to find the answer to a subtraction fact. We discussed subtraction problems being comprised of a whole that takes away a part to find the other part. Then, we did addition problems being comprised of two parts added together to find the whole. We used cubes to help model the add to subtract problems. Together, we colored Hester the witch. Gracyn rolled a die and then added 10 to find the correct number to color.
