Match the following Models & Properties of Addition

• Angle-Addition Property

• Suppose a count or measure x is put together with a count or measure y with the same units. If there is no overlap, then the result has count or measure x + y

• Putting Together Model

• If ray OB is in the interior of angle AOC, m angle AOB + m angle BOC = m angle AOC

• Commutative Property of Addition

• For any numbers a and b, a + b = b + a

• Slide Model for Addition

• If a slide x is followed by a slide y, the result is a slide x + y

• Betweenness Property

• Given three distinct points A, B, and C, if point B is between points A & C on line segment AC, then AB + BC = AC
