Count One and Two

Overview

Students build one-to-one counting skills by counting, making, and recording sets of 1 and 2 objects. The lesson uses short routines, movement, and clear transitions to support kindergarten students who are developing classroom listening and learning behaviors.

Learning intentions

Students will be able to:

• Count forward from 1 to 10 while saying one number for each object.
• Count out a group of 1 or 2 objects when given a number.
• Match the quantities 1 and 2 to the written numerals.
• Explain how they know a group has 1 or 2 objects.

Success criteria

• I can touch and count each object one time.
• I can make a group of 1 or 2 objects.
• I can match a group to the numeral 1 or 2.
• I can tell or show how many objects I counted.

Curriculum links

Lesson structure (45 minutes)

1. 0–5 min · Welcome and counting hook. Teacher gathers students at the carpet, opens the counting hook slide, and shows one teddy bear, then two teddy bears. Ask, “How many do you see?” Students look, show 1 or 2 fingers, and practice the routine: eyes watching, hands still, voice off while listening.

2. 5–12 min · Model one-to-one counting. Teacher uses the counting demonstration slides and models touching each counter once while saying, “One,” then “One, two.” Emphasize that the last number said tells how many altogether. Students count with the teacher using finger taps on their knees, then count two classroom objects together.

3. 12–20 min · Make a group. Teacher gives each student a small mat and a cup of counters. Display the directions on the make-a-group instruction slide: “Listen, take, place, count.” Call out “Make 1” and “Make 2,” pausing between turns. Students take the requested number of counters, place them on the mat, touch-count them, and hold up the matching number of fingers. Circulate and quietly guide students who grab several objects at once.

4. 20–28 min · Partner count and match. Teacher pairs students and distributes the count-and-match worksheet. Model one example: place 1 counter beside the first picture, count it, and draw or trace the numeral 1; repeat with 2. Students work with a partner to count picture groups of 1 or 2, circle the matching numeral, and complete simple numeral-tracing tasks. Partners take turns as “counter” and “checker,” with the checker asking, “How many?”

5. 28–35 min · Movement counting game. Teacher returns to the movement game slides and displays one or two dots. Students stand beside their desks or on a carpet spot. For one dot, they make one quiet clap; for two dots, they make two quiet claps. Repeat with stomps, taps, or hops as space allows. Students must wait for the signal, count the movements, and freeze when the slide changes.

6. 35–41 min · Guided practice and correction. Teacher shows sets of 1 or 2 objects on the “How many?” discussion slides, including one carefully arranged set and one scattered set. Ask, “How many? How did you count?” Invite several students to touch-count or explain. Deliberately make one mistake, such as saying “one” for two objects, and have students respectfully correct the count.

7. 41–45 min · Exit check and closing. Teacher gives each student either a 1 or 2 card and asks them privately to place that many counters beside the card, then state or show the quantity. Students complete the check one at a time while others practice counting softly from 1 to 10. Close with the counting song or final prompt on the closing review slide: “Show me 1. Show me 2.”

Resources

• the counting and movement slide deck
• the count-and-match worksheet
• Small counters, connecting cubes, or plastic bears
• Individual counting mats
• Numeral cards showing 1 and 2
• Pencils or crayons
• Carpet spots or desk spaces
• Teacher checklist for counting behaviors

Assessment

• During modeling and group-making, check whether each student touches one object for each number word and stops at the requested quantity.
• During partner work, listen for accurate use of “one” and “two,” correct numeral matching, and explanations such as “I counted two.”
• Use the final one-to-one exit check to record whether each student can make a group of 1 or 2 and identify the matching quantity.

Differentiation

• For students needing support, work with only one counter at first, use a larger mat with one or two marked spaces, provide hand-over-hand modeling when appropriate, and repeat directions with gestures: “Take one. Put it down. Count.”
• Provide visual numeral cards, dot patterns, finger models, and sentence frames such as “I counted ___” or “I made ___.”
• For EAL students, pair spoken number words with gestures and visuals, model slowly, and accept pointing, fingers, object placement, or home-language responses as evidence of understanding.
• For students ready for more challenge, ask them to start counting at 2, make a group of 2 without looking at a model, or compare two groups using “more,” “fewer,” or “same.”
• Support attention and sensory needs with a predictable signal, short directions, assigned carpet spots, movement breaks, and a quiet workspace or adult check-in when needed.
