Today we became subtracticians. That's a made up word for learning subtraction and becoming experts all in one day. We practiced making fact families and learned that addition problems can quickly be turned into subtractions problems. Can you use the number 4, 6, and 10 to find two addition and two subtraction problems? We sure can!
4+6=10 6+4=10 10-4=6 10-6=4
With addition you always add the two parts together to find the whole. With subtraction you always start with the whole and take away one of the parts.
