Tens And Ones

Understand The Following As Special Cases:

a) 10 can be thought of as a bundle of ten ones — called a “ten.”
b) The numbers from 11 to 19 are composed of a ten and one, two, three, four, five, six, seven, eight, or nine ones.
c) The numbers 10, 20, 30, 40, 50, 60, 70, 80, 90 refer to one, two, three, four, five, six, seven, eight, or nine tens (and 0 ones).

Common Core: 1.NBT.2

Learning Targets:

• I can represent 10 as ten ones.
• I can represent numbers 11 to 19 as a ten and some ones.
• I can represent multiple sets of ten using number names (2 tens is 20).
• I can explain the value of each digit in a two-digit number (place value).
• I can use base ten manipulatives (e.g., base ten blocks, Digi-Blocks, Unifix Cubes, ten frames, interlocking base ten blocks) to represent two-digit numbers
• I know how to connect numerals, words, and quantities
• I know that two-digit numbers are composed of bundles of tens and leftover ones
• I can count by tens and ones
• I know how to use base ten manipulatives (e.g., base ten blocks, Digi-Blocks, Unifix Cubes, ten frames, interlocking base ten blocks) to build and compare ten ones and ten
• I can use base ten manipulatives (e.g., base ten blocks, Digi-Blocks, Unifix Cubes, ten frames, interlocking base ten blocks) to build and compare 11 to 19
• I can match the concrete representations of 11 through 19 with the numerical representations
• I can use base ten manipulatives (e.g., base ten blocks, Digi-Blocks, Unifix Cubes, ten frames, interlocking base ten blocks) to build and model the counting by tens

Concept Of Place Values

The Ones Place
The ones place is the position of the digit that represents individual items. It’s always the rightmost digit in a whole number.

The Tens Place
The tens place is the position of the digit directly to the left of the ones place. It represents groups of ten.

Putting Tens and Ones Together to Make Two-Digit Numbers
When you have a number with two digits, the digit on the left is in the tens place, and the digit on the right is in the ones place. They work together to show the total value.

How to Teach Tens and Ones (Activity Ideas)

• Base Ten Blocks: Use the long “tens rods” and the small “ones cubes” to build numbers.
• Bundles of Sticks: Use craft sticks. Bundle 10 sticks with a rubber band to make a “ten.” Keep single sticks for “ones.”
• Place Value Charts: Draw a simple chart with two columns, labeled “Tens” and “Ones.” Write numbers in the chart or place manipulatives there.
• Counting Games: Have children count out loud, emphasizing the groups of ten (“10, 20, 30…”).
