๐ Skip Counting Word Problems vs. Addition Word Problems: What's the Difference?
Word problems can sometimes feel like a puzzle! First graders often encounter both skip counting and addition word problems. While they both involve putting numbers together, the way they do it is different. Let's break it down.
โ Definition of Addition Word Problems
Addition word problems involve combining individual, distinct quantities. The key is that you're adding single units together.
- ๐ Example: "Sarah has 3 apples, and John has 2 apples. How many apples do they have in total?"
- โ Solution: You're adding individual apples: $3 + 2 = 5$ apples.
๐ข Definition of Skip Counting Word Problems
Skip counting word problems involve adding the same quantity repeatedly. This is like counting in groups.
- ๐ Example: "A car has 4 wheels. How many wheels do 3 cars have?"
- โ Solution: You're adding the same number (4) multiple times: $4 + 4 + 4 = 12$ wheels. This can be represented as skip counting by 4s three times: 4, 8, 12.

๐ Key Takeaways
- ๐ Addition problems deal with adding different amounts together, whereas skip counting deals with adding the same amount repeatedly.
- ๐ก Skip counting helps build a foundation for multiplication later on! Think of it as repeated addition.
- ๐ When solving word problems, carefully look for keywords that indicate whether you're adding different amounts or adding the same amount multiple times.
