Finding Multiples by Skip Counting
Finding Multiples by Skip Counting is a Grade 3 math skill from Eureka Math showing that multiplication can be computed by skip-counting by the group size, saying one number for each group added. To find 5 × 4, skip-count by 4 five times: 4, 8, 12, 16, 20. Skip-counting connects repeated addition to multiplication and helps students build multiplication fluency before memorizing all facts. It provides a reliable fall-back strategy and reinforces number sense for multiples and patterns in multiplication tables.
Key Concepts
To find the total number of objects in equal groups, skip count by the number of items in each group. You say one number for each group.
Common Questions
What is skip-counting and how does it relate to multiplication?
Skip-counting means counting forward by a fixed amount instead of by ones. It directly models multiplication: skip-counting by 4 five times (4, 8, 12, 16, 20) gives the same result as 5 × 4.
How do you find 6 × 3 by skip-counting?
Skip-count by 3 a total of 6 times: 3, 6, 9, 12, 15, 18. The final number, 18, is the product of 6 × 3.
Why do you say one number for each group when skip-counting?
Each jump in skip-counting adds one more group of the given size. Saying one number per jump keeps track of how many groups have been counted.
What is the connection between skip-counting and repeated addition?
Skip-counting by 4 five times (4, 8, 12, 16, 20) is the same as 4 + 4 + 4 + 4 + 4 = 20. Both methods count equal groups; skip-counting is just faster.
