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.

Description of Mathematics
Number Framework Stages 5 and 6
Required Resource Materials
Play money (Material Master 4-9).
Activity
Preliminary Knowledge
The students need to know 10 hundreds make 1 thousand and vice versa, and 10 thousands make 1 ten thousand and vice versa.
Using Materials
Problem: The Bank of Mathematics has run out of $1000 notes. Alison wants to withdraw $2315 in $1, $10 and $100 dollar. How many $100 notes does she get?
Examples. Repeat for: $2601, $3190, $1555, $1209, $2001, $1222, $2081….
Using Imaging
Problem: Tickets to a concert cost $100 each. How many tickets could you buy if you have $3215?
Write $3215 on the board. Shield 3 one thousands, 2 one hundreds, 1 ten and 5 ones. Ask the students what you can see. Discuss how many hundred dollar notes you could get by exchanging the thousands. Discuss which notes are irrelevant (the ten and theones).
Shielding and Imaging only: Examples. Find the number of hundreds in: $1608, $2897, $2782, $3519, $3091, $4000….
Using the Number Properties
Examples. Find the number of hundreds in: 3459, 8012, 9090, 6088, 3280, 5823, 7721, 2083….
Challenging examples. Find the number of hundreds in: 13 409, 28 002, 78 370, 12 088, 45 290, 82 356, 21 344….
Find the number of tens in: 3709, 8002, 8579, 5208, 4829, 82 333, 12 897, 30 897, 89 000, 50 890
