To simplify adding Jeannie's score of 245 and Kevin's score of 227, we can break apart one addend to make a ten. For example, by adjusting Kevin's score by 3 points (227-3=224) and adding it to Jeannie's score (245+3=248), and then adding these new scores (248+224) we easily get a total of 472 points. ;

To find the total number of points Jeannie and Kevin scored, you can make use of a common strategy in addition known as 'making a ten'. This method involves rearranging one of the addends to create a sum that includes a multiple of ten, which makes the addition easier to carry out. For example, when adding Jeannie's score of 245 and Kevin's score of 227, we can break apart 227 into 220 and 7.
Then, we can add 245 to 220 first, giving us an easy sum of 465 (since both numbers end in a 5 or a zero). Finally, we add the remaining 7 to get a total of 472. This way, we did not have to juggle the smaller units and tens separately and could more easily visualize the addition.
