Description

Strengthen number sense and subitizing fluency across numbers 1-20 with this hands-on clip card and worksheet set for kindergarten. Students work with eight different number representations, including ten frames, dice, subitizing dots, dominoes, fingers, tally marks, and popsicle sticks, clipping the pictures that match the focus number in the center. Companion cut-and-paste number sort worksheets give students a second format to practice sorting and identifying the same representations.

 

What’s Included

 

Subitizing Clip Cards (20 cards, numbers 1-20)

 

  • One card per number with the focus number displayed in the center
  • Eight representations appear around each card: ten frames, dice, number dots, dominoes, fingers, tally marks, and counting sticks
  • Teen number cards (11-20) include base ten blocks to support early place value recognition
  • Students identify and clip the pictures that match the focus number

 

Number Sort Worksheets (20 worksheets, numbers 1-20)

 

  • One cut-and-paste worksheet per number
  • Students sort picture representations into “Number [X]” and “Not Number [X]” categories
  • Same number representations as the clip cards for consistent, connected practice

 

Why Teachers Love This Resource

 

  • Builds real number sense: Students recognize numbers across eight representations, not just rote counting
  • Two complementary formats: Clip cards for hands-on math center practice, worksheets for independent recording and quick assessment
  • Covers numbers 1-20: Teen number cards include base ten blocks, making early connections to place value
  • Easy to differentiate: Start with numbers 1-10 for students still building foundational fluency, then extend to teen numbers as students grow
  • Consistent, low-prep format: Same clear structure for every number so students know exactly what to do
