Big Ideas:
Skip counting by fives and tens is important in counting and using money.
Skip counting can be used to add the same numbers together multiple times.
This task asks students to apply what they know about skip counting to money. This gives students the opportunity to think about why knowing how to count by 5s and 10s is useful in real life and what it can be used for. Students are also asked to use skip counting to find the sum of the boys' money, giving students the opportunity to approach the problem in whatever way they feel comfortable. This prepares students for 2-digit addition using many strategies including skip counting and place value.
