Keywords:
Specific Learning Outcomes:

Recall the number of tens and hundreds in 100s and 1000s.

Find out how many ones, tens, hundreds and thousands are in all of a whole number.

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….
