Counting, Subitising, and Number Fun
Year 1 Mathematics Exploring numbers through play and discovery
What is Subitising?
Seeing 'how many' without counting one by one Using our eyes and brain to recognise numbers quickly Like magic - we just KNOW how many! Works best with small groups of objects
Quick Look Game
I'll show you some dots for just 2 seconds Shout out how many you see! No counting allowed - just look and know Ready for your number superpowers?
Counting Forwards and Backwards
We can start counting from ANY number Count forwards: 7, 8, 9, 10, 11... Count backwards: 15, 14, 13, 12, 11... Let's practice together!
Number Hop Challenge
Stand on our giant number line I'll call out a starting number Count forwards or backwards as we hop Listen carefully for my directions!
Combining and Separating Numbers
{"left":"Put groups together to make bigger numbers\nTake some away to make smaller numbers","right":"Use our 10-frames to organise our thinking\nTalk about what we notice"}
Let's Think Together
If you see 4 kumara and someone gives you 3 more, how many do you have altogether? Can you show me using your counters? What other ways could we make 7?
Today We Learned
We can see numbers quickly without counting - that's subitising! We can count forwards and backwards from any number We can combine and separate groups to explore numbers Talking about math helps us learn!
