Numbers 1-20 — Vocabulary Flashcards

About This Resource

A set of 20 print-and-cut flashcards teaching numbers 1 through 20, each shown as a small cluster of counted objects paired with its numeral and number word, plus a matching set of word-only cards.

Overview

Each picture card shows a numeral and number word alongside a counted group of objects — stars, apples, balloons, flowers, cubes, or fish, cycling through the set — so students see the exact quantity a number represents rather than memorizing a fixed picture per number. Pages 2-4 hold the 20 picture cards; pages 5-7 hold matching word-only cards for review and games. A cover page explains what's inside and how to use the set.

Grade 1 35-45 Minutes Vocabulary Numbers

How to Present

Cut out the cards along the dashed lines.
Use the picture cards to teach counting and number recognition from 1 to 20.
Mix picture and word cards for a matching game.
Hold up a card and ask, "How many? What number is it?" — students answer!

Games & Speaking Activities

Lay the 1-10 picture cards face-up around the room. Call out a number, and have students race to touch or stand next to the matching card.

Teacher Tips

Introduce numbers in small batches of 5 at a time (1-5, 6-10, 11-15, 16-20) rather than all 20 at once — Grade 1 students retain new number vocabulary far better with a short, repeated set than with a long list introduced in a single sitting.

Learning Objectives

Students will be able to recognize and name numbers 1-20 when shown a counted group of objects or a numeral.

Differentiation

Support: start with only numbers 1-5 before introducing the full 1-20 set.

Extension: have students sort the picture cards into groups of even and odd numbers before the formal Counting Activity (Resource 4) is introduced.

Assessment

Informal — observe whether students can correctly count and name each number when a card is held up, and whether they can find the matching word card during a review game.
