Problem Solving Powerpoints: Compare Problems

Compare stories are the most difficult types of stories to tell. There are three types of comparison stories. The first type of comparison story is where two different things are being compared. For example,  Lucy had 5 rings and Maria had 7 rings.  Who had more?  How many more? Or, How many fewer rings does Lucy have than Maria?  In a difference problem, when you say fewer, it is considered a more difficult version of the problem. There is another version of the compare the difference problem. For example, Jean has 20 marbles and Mike has 10. How many more marbles does Mike need to have the same amount as Jean?

The second type of comparison story is where the bigger part is unknown. In this type of story, we are looking for the bigger amount. For example, Luke had $57 and Marcos had $19 more than Luke. How much does Marcos have? How much do they have altogether? Another example, Luke had $57. This is $10 less than Marcos. How much does Marcos have? There are two types of this problem. When you say less and you are looking for more, it is considered the harder part because it is counterintuitive. The task is to find the bigger part.

The third type of comparison story is where the smaller part is unknown. In this type of story, we are looking for the smaller amount. For example, Luke had $57 and Marcos had $10 less than Luke. How much does Marcos have? How much do they have altogether? Another example, Luke had $57. This is $10 more than Marcos. How much does Marcos have? There are two types of this problem. When you say more and you are looking for the smaller part, it is considered the harder version because it is counterintuitive. The task is to find the smaller part.
