| Full lesson | Create for a teacher a set of content for giving a lesson, beginning with the lesson plan. Each new block of materials must begin with an H1 heading (other subheaders must be H2, H3, etc). When you describe required pictures, write those descriptions in curly brackets, for example: {A picture of a triangle} |

This lesson aligns with the Australian Curriculum: Mathematics (ACMNA001), focusing on developing understanding in number patterns and counting.
| Step Number | Step Title | Length | Details |
|---|---|---|---|
| 1 | Introduction to Subitising | 5 min | Introduce the concept of subitising. Use flashcards to show groups of 1 to 6 objects. Discuss how quickly we can recognize the number without counting. |
| 2 | Group Activity | 10 min | Divide students into pairs. Give each pair a set of flashcards. Have them show each other cards and call out the number they see without counting. |
| 3 | Physical Activity Break | 5 min | Engage students in a quick physical activity such as "Jump and Count." Every time they jump, they call out a number, reinforcing their number sense. |
| 4 | Individual Practice | 5 min | Provide counting manipulatives. Ask students to select a group of objects and subitise by placing them in front of them while calling out the quantity. |
| 5 | Reflection and Wrap-Up | 5 min | Gather students and discuss what they learned about subitising. Ask guiding questions about their experiences during the activities. Encourage recounting their favourite part. |
| 6 | Homework Assignment Check | 0 min | Review homework without students presenting. Collect any practice sheets for feedback. |
"Good morning, everyone! Today, we are going to learn something really fun called subitising. Who knows what that might mean? (Pause for responses.)
Subitising is a clever way of looking at a group of things and knowing how many there are without actually counting them one by one. Let's take a look at these flashcards I have. (Show flashcard with one object.)
How many do you see here? (Encourage responses.) Yes, that's right! There’s one! Now, let’s try another. (Show flashcard with two objects.) How many are on this card? Right, there are two!
Let's go all the way up to six. (Show each flashcard from three to six, encouraging students to respond quickly.)
Fantastic! You all did great recognizing those numbers without counting them. That's the power of subitising!"
"Now, it's time to work with a partner! I want everyone to find a buddy. (Give them time to pair up.)
Each pair will get a set of flashcards. Take turns showing each other a card. When your partner shows you a card, see if you can shout out the number without counting! Ready? Go!
(As they work, walk around and listen to their answers. Offer encouragement and support where needed.)
Great job, everyone! I saw some excellent subitising happening!"
"Alright, let's take a little break to move our bodies! We’re going to play Jump and Count. Every time you jump, shout out a number. This is a fun way to keep our minds and bodies active!
Let’s start! Jump and call out numbers together. One, two, three… (Encourage students to jump and call out numbers for a minute or so.)
Wow, you are all such great jumpers and counters! Now that we’ve gotten our energy out, let's get back to some more fun activities!"
"Now, I have some counting manipulatives for each of you. These are blocks and counters that you can use.
I want you to pick a small group of objects—maybe three or four—and place them in front of you. Look at your group and try to subitise. Can you shout out how many you see without counting?
(Provide time for them to practice and assist as necessary.)
Excellent work, everyone! I can see you are really grasping the idea of subitising!"
"Let’s all gather back together and talk about what we learned today. What is subitising? (Encourage responses.) Yes, it’s recognizing how many there are without actually counting them!
What were some of your favourite parts of today’s lesson? (Listen to student responses and ask follow-up questions to encourage sharing.)
Fantastic! I'm so proud of the progress you all made today. Remember, practicing subitising will help you recognize numbers faster!"
"Now, before we end our session, I want to check your homework from last time. You were to find small groups of objects at home and practice subitising, right? I won’t ask you to share just yet, but I’ll collect your practice sheets later for feedback.
Great job today, everyone! Remember to keep practicing your subitising at home. I can’t wait to hear all about your discoveries in our next lesson!"

Here's a fun little poem to remember the exercises:
Move and Groove!
Jumping jacks, one, two, three,
Squats to sit, just like me!
Circle your arms, big and small,
Touch your toes and stand up tall.
High knees marching, nice and bright,
Lunging sideways, left and right.
Wall push-ups to build some power,
Marching in place, let’s not sour!
Twist your hips like a fun dance,
Reach up high, give it a chance!
Get your bodies moving now,
Let's stay active, take a bow!
