Description

The Tens Ones Worksheet helps first grade students build a strong place value foundation by breaking two-digit numbers into tens and ones. Understanding that a number like 45 is made of 4 tens and 5 ones is one of the most important early math skills, and this tens ones worksheet gives children a clear, hands-on way to see and count each place. With friendly base-ten blocks to guide them, young learners connect the picture of a number to the digits they write.

On this worksheet, students look at six sets of base-ten blocks, count the tall tens rods and the small ones cubes, and then write how many tens and ones each set shows before recording the full two-digit number. The activity moves from a concrete model to written numbers, which is exactly how first graders learn place value best. Teachers can use it for morning work, a math center, guided practice, or a quick check for understanding, and an answer key is included to make grading fast and simple.

What’s Included

  • A printable first grade place value worksheet with six base-ten block problems
  • Tens rods and ones cubes for counting and writing the tens, the ones, and the number
  • A complete answer key for quick and easy grading
  • A clean, colorful design built for young learners

Why It Helps Kids

This activity helps children in three important ways. First, the base-ten blocks turn an abstract idea into something students can see and count, so place value finally clicks. Second, writing the tens, the ones, and the final number in one step strengthens the link between the model and the digits. Third, the short, focused format keeps young learners confident and successful instead of overwhelmed, building positive math habits early.

Teacher and Parent Ideas

Pair this first grade base 10 worksheet with real base-ten blocks or connecting cubes so children can build each number before they write it. Ask students to say the number out loud, such as “4 tens and 5 ones make forty-five,” to reinforce the language of place value. At home, families can hunt for two-digit numbers on signs and mailboxes and break them into tens and ones together. You can also turn it into a game by calling out a number and having children draw the matching tens and ones.
