What Are Ones and Tens Place Values? Every digit, be it a two-digit number or more than two digits, has a place value. To make up large numbers, mathematics uses a system that is known as a place value system. It is the place of a digit in a number represented by its position in the number. The very first position in a digit is the ones position, and the second position is the tens position, moving from right to left. For example, the number 58 is a two-digit number. Understanding the position of 5 and 8 in this number is the understanding of place value. In this two-digit number, there are two place values. Understanding that 58 is made up of 50 and 8 rather than 5 and 8 is important. The place values increase with the addition of digits in the number. In the above example, 58, the place of 8 is at ones position and the place of 5 is at tens position. As the digits increase, the place values go from ones to tens to hundreds to thousands and so on, from right to left. These worksheets introduce the concept of place value held within double digit numbers.

- Visual Ten Places Step-by-step Lesson-
We use blocks to represent the tens place. It makes for an easy transition from numbers.

- Visual Ones and Tens Place
Explained- We work on a smaller scale to fully explain the concept.

- Visual Place Number Practice 5
Pack- Count the groups of ten and the singles.

- Ones and Tens Place Practice Worksheet-
This is a nice way to further explore this skill.

- Grouping Worksheet Practice 5 Pack- Figure
out how many tens and ones there are in this set of practice sheet
with visuals. Write in how many groups of ten you have and count up how many trees you have remaining.

- Missing Place Numbers Guided Lesson
- A great mix. Includes the missing ones place, noting ones and
tens place, and block counting.

- Visual Guided Lesson Explanation
- I tried to make this one as visual as possible to make it a bit
more easy for students.

- Mixed Practice Problems
- It kind of picks up where the guided lesson has led us. Then it
goes a bit overboard with the visual place blocks.

- Matching Ones and Tens Places
- Match the numbers to their place values.

#### Guided Lessons

I covered current and past teaching methods to let teachers at all ranges have resources for their method.

- Break Apart the Numbers Guided Lesson 1 - This is more an older method teachers used until spreadsheets became the toast of the town.
- Tens and Ones Guided Lesson 2 - If the previous sheet gave students trouble, this one should clear it up for them.
- How Many Circles Guided Lesson 3 - Splitting shapes up into parts leads itself to integers.
- Tens and Ones Guided Lesson Explanation - This one is nice because we go with both shapes and integers.
- Tens and Ones Chart Guided Lesson Explanation 2 - Using columns is the most common method I see teachers use today.

#### Practice Worksheets

These sheets are all working this skill with many different methods of performing the same overall task.

- Charting Ones and Ten Place Worksheet - Given a number, decide which integer is the tens and one place.
- Write the Numbers Described Worksheet - Lets play "Name that Number!"
- Missing Numbers Worksheet- We adapt this skill to using it in operations.
