How Many More?

The Ministry is migrating nzmaths content to Tāhurangi.           
Relevant and up-to-date teaching resources are being moved to Tāhūrangi (tahurangi.education.govt.nz). 
When all identified resources have been successfully moved, this website will close. We expect this to be in June 2024. 
e-ako maths, e-ako Pāngarau, and e-ako PLD 360 will continue to be available.

Purpose

The purpose of this activity is to help students learn groupings:

  • within 10, for example 3+7=10
  • with 5, for example 5+2=7
Achievement Objectives
NA1-3: Know groupings with five, within ten, and with ten.
AO elaboration and other teaching resources
Specific Learning Outcomes

recall groupings within 10. For example 3 and 7 make 10; 8 and 2 make 10.

Required Resource Materials
Slavonic Abacus
Activity

The abacus can be used effectively to help develop and reinforce student knowledge of groupings. These include:

  • Develop knowledge of groupings within 10 (for example, 2+8=10) by pushing across a small number of beads and asking
    How many more to make 10?
  • Develop knowledge of groupings with 5 (for example 5+2=7) by pushing across 5 beads and asking
    How many more to make 7?
  • Develop knowledge of groupings with 5 (for example 5+4=9) by pushing across a small number of beads, for example 9, and ask
    How many beads did I just push over?
    How do you know it’s 9 without counting the beads?     Encourage answers that focus on the groupings such as “I know 5 and 4 is 9” or “I know 9 is 1 less than 10.”

The groupings identified using the abacus can be reinforced using finger patterns.
