9.4 Count Within 1,000 by Fives and Tens

For full lesson outline please see Advantage Math 9.4

(This lesson would be better done in-class using the hundreds chart to help students to count by 5s and 10s. Follow the outline in Advantage Math 9.4)

Standards taught in this less:

*2.NBT.2: Count within 1,000; skip count by fives, tens, and hundreds.

(*priority standard)

Mathematical Practice:

2.MP.7: Look for and make use of Structure.

Math Objective:

Students will count forward and backward by fives and tens within 1,000.

Vertical Alignment:

In first grade students will cover standard:
- 1.NBT.1: Count to 120, starting at any number less than 120. In this range read and write numerals and represent a number of objects with a written numeral.
Then in third grade they will cover:
- 3.OA.9: Identify arithmetic patterns (including patterns in the addition table or multiplication table) and explain them using properties of operations. For example, observe that four times a number is always even, and explain why four times a number can be decomposed into two equal addends.

Vocabulary: Skip count

What patterns do you notice in the two charts?

🤔Explore A

Nearpod – Students have learned to count by 5s in the 1-100.

Use the highlight tool to count by 5s. See if you can see a pattern.
Did your chart look like this? What do you notice about this chart?
Let’s count by 5’s starting at 105 and going to 200- Students will either follow the Nearpod recording or this can be done in class.
What number would come after 200 and why?
Play game with hand signals either on the Nearpod or in class.

💬Discuss A

What pattern did you see when you counted by 5s? How do you know what number will come next?

🚀Launch B

What pattern do you notice in this chart? How is this different than counting by 5s?

🤔Explore B

Nearpod
Fill in the pattern of skip counting by tens on the chart.
What number would come next after 800 if we were counting by 10s?
Let’s count by 10s starting at 300. Students will either count in class or on the Nearpod.
Play game with hand signals counting by tens.

💬Discuss B

How is counting by 5s and 10s in larger numbers than 100 similar to counting by 5s and 10s in smaller numbers than 100?
