Core concept: We can make connections between collections.
Learning Intention:
Students are learning that:
the number before is one less and the number after is one more than a given number
objects from a larger collection can be counted and compared.
Success Criteria:
Students can:
find a number that is one less and one more
keep track of the count to find which collection has more.
Daily number sense:Hunting hopscotch – 20 minutes
Build student understanding of the number before as one less and the number after as one more than a given number by playing hopscotch.
Activity:Quick quokkas – 30 minutes
Explain that quokkas are a small marsupial native to Australia and are herbivores that eat native grasses and leaves, especially leaves of wattle trees.
Consolidation and meaningful practice:Deadly dominoes – 15 minutes
Introduce ‘deadly dominoes’ by displaying Resource 7: Domino template.
Model how to play ‘deadly dominoes’ by facing the set of dominoes upwards and select a domino from a larger collection. Find the total of the domino dot pattern by subitising or counting with one-to-one correspondence. Find another domino that ‘is the same as’ or has the same total number of dots. Find another 2 dominoes, one less and one more than the given number (see Figure 3).
