Understanding Place Value

  • Tens and Ones: Numbers are made up of digits, and each digit has a place value. The two main place values are tens and ones.
    • Tens: Groups of ten.
    • Ones: Individual units.

Counting and Grouping

  • Counting to 30: Practice counting from 1 to 30.
  • Grouping: Group objects into sets of ten to understand tens.
    • Example: 15 can be grouped as one group of ten and five ones.

Representing Numbers

  • Visual Representation: Use objects like blocks or counters to represent numbers.
    • Example: 23 is shown as two groups of ten and three individual blocks.
  • Drawing: Draw groups of ten and ones.
    • Example: Draw two sets of ten circles and three additional circles for 23.

Writing Numbers in Tens and Ones

  • Number Formation: Write numbers showing tens and ones.
  • Using Place Value Chart: Use a place value chart to separate tens and ones.

Practice with Examples

  • Examples:
    • 11 = 1 ten and 1 one
    • 22 = 2 tens and 2 ones
    • 30 = 3 tens and 0 ones

21 = ​_______tens + ​_____ones

  • Remember the place values:
tensones
21
  • 21 = 2 tens + 1 one

11 = ​_______tens + ​_____ones

  • Remember the place values:
tensones
11
  • 11 = 1 ten + 1 one

18 = ​_______tens + ​_____ones

  • Remember the place values:
tensones
18
  • 18 = 1 ten + 8 ones
