Learning how to skip counting by 5s, 10s, and 100s is a second grade, Common Core math skill: 2.NBT.2. Below we show two videos that demonstrate this standard. Then, we provide a breakdown of the specific steps in the videos to help you teach your class.
Your students should be familiar with the first grade skill of counting up to 120 starting from any number below 120 (1.NBT.1), this skill helps them understand greater or less than values. The second grade skill is also closely linked to the first grade skill of understanding place values (ones and tens) in two-digit numbers (1.NBT.2).
Comparing large numbers as greater than, less than, and equal to will help your students understand future concepts in third grade. In third grade, your students will learn how to interpret the products of whole numbers (i.e. 8 x 3 is the same as 8 groups of 3 objects each) (3.OA.1). They will also learn to use multiplication and division within 100 while solving word problems in situations that involve “equal groups, arrays, and measurement quantities” (3.OA.3).
Common Core Standard: 2.NBT.2 - Count within 1000; skip count by 5s, 10s, and 100s
Students who understand this principle can:
2 Videos to Help You Teach Common Core Standard: 2.NBT.2
Below we provide and breakdown two videos to help you teach your students this standard.
Video 1: Skip Counting Bows, Blocks, Balls and More
The video teaches students how to count groups of objects by skip counting. The video explains that skip counting is counting by any number other than 1.
For example, you can skip count by 2s: 2, 4, 6, 8, 10 and so on.
The video then presents a group of bows and sorts them into groups of 5 so your students can count them by 5’s.
The next set of examples demonstrate how students can use skip counting by 5s, 10, and 100s to identify how many individual pieces there are.
Video 2: Skip Counting Oranges, Cakes, and Other Objects
Boddle begins by explaining how to count by 5s. A good trick to help your students remember how to count by 5s is that the last digit of each count alternates between 5 and 0.
The first two examples demonstrate how to count by 5s.
The next set of examples show your students how to count by 10s. This time, the last digit will stay 0, or the same. Only the first digit will change.
The last example demonstrates how to count by 100s. It is very similar to counting by 10s, but instead of having one zero at the end, there will be two.
