Building relationships - more than, less than, equivalent in value to
This resource was developed in partnership with the NSW Mathematics Strategy Professional Learning team, Curriculum Early Years and Primary Learners, and Literacy and Numeracy.
Using the resource
This resource is the third section of a 6-part resource supporting number knowledge. Use this resource in conjunction with the other resources in this series in order to support a connected network of critical mathematical concepts, skills and understanding.
Supporting tasks
Full instructions on how to use each of these tasks, including materials, related tasks and learning intentions are included in the resource, are available via the Universal Resources Hub.
Balancing numbers
When students are comparing 2 sides of a balance arm scale, they are physically exploring the relationship of equivalence.
Task 1: Balancing numbers
Students watch ‘Balancing Numbers 1’ and consider a series of questions.
Variation: Teachers could modify this task to explore equivalence in quantity by using different coloured blocks
Arranging quantities
The different ways we arrange quantities on structures such as ten-frames can help students to notice different parts as well as noticing relationships to other wholes. Provide students with multiple opportunities to explore and investigate different representations and arrangements of numbers, using various structures and tools.
Task 2: Number Busting (7 is...)
Students watch ‘Number Busting (7is..) and ‘Number Busting with Lego’ and organise, describe and reflect on findings.
Task 3: Go fish relationships
Students watch ‘Go fish relationships’ to learn how to play
Variation: Play continues until there are no cards left. The player with the most pairs is the winner.
Subitising
Frequent meaningful practice with different spatial patterns and structures, including standard and non-standard structures, helps build strong mental images and the capacity to visualise quantities. Strong mental images and visualisation supports students to use increasingly flexible problem-solving strategies.
Support students to develop rich and varied mathematical vocabularies, connecting words to meaningful experiences. Use a broad range of representations and use dialogic practices like revoicing.
Task 4: Subitising 6 – one less than
Students watch ‘Subitising 6 - one less than’ and consider ‘how many’ they see without having to count
Task 5: Subitising – more, less, the same
Students watch ‘Subitising - more, less, the same’ and work out what quantities are more, less or the same.
