Compare Numbers 0–20
A number comparison worksheet for Kindergarten using the symbols greater than (>), less than (<), and equal to (=) with numbers in the 0–20 range. Children compare pairs of numbers and write the correct symbol, building the formal inequality vocabulary and symbolic notation used throughout mathematics.
Frequently Asked Questions
What comparison skills does the Compare Numbers 0–20 worksheet develop for kindergartners?
The worksheet develops numeral comparison — the ability to look at two written numbers and determine which is greater, which is less, and whether they are equal. This extends the concrete quantity comparison of pre-K (more or fewer objects) to abstract numeral comparison, directly addressing CCSS.MATH.CONTENT.K.CC.C.7: 'Compare two numbers between 1 and 10 presented as written numerals' (extended to 20 for advanced kindergartners).
What strategies should kindergartners use to compare numbers within 0–20?
Three main strategies: (1) use a number line — the number that is further right is always greater; (2) compare tens digits first, then ones digits — all teen numbers are greater than all single-digit numbers; (3) for two single-digit numbers, use quantity knowledge (which number represents more objects?). The Compare Numbers 0–20 worksheet builds fluency with all three strategies through repeated numeral comparison practice.
How does comparing numbers 0–20 prepare kindergartners for greater than and less than symbols?
Understanding that 15 is greater than 8 is the conceptual prerequisite for writing 15 > 8. The greater than (>) and less than (<) symbols are introduced in Grade 1, but the comparison concept must be solid before symbols are introduced. Kindergartners who can reliably compare numbers 0–20 through the Compare Numbers worksheet are fully prepared for the formal inequality notation they will encounter in Grade 1.
Is comparing numbers within 20 appropriate for all kindergartners or only advanced students?
CCSS explicitly requires numeral comparison within 10 for all kindergartners, with comparison within 20 as an extension standard. The Compare Numbers 0–20 worksheet is appropriate as an enrichment activity for kindergartners who have mastered comparison within 10, and as a review activity for students transitioning to Grade 1. For kindergartners who are still developing single-digit numeral comparison, the 0–10 comparison worksheets should be consolidated first.
