# Place Value Houses

Thanks for visiting NZMaths.
We are preparing to close this site by the end of August 2024. Maths content is still being migrated onto Tāhūrangi, and we will be progressively making enhancements to Tāhūrangi to improve the findability and presentation of content.

Achievement Objectives
NA4-6: Know the relative size and place value structure of positive and negative integers and decimals to three places.
NA2-2: Know forward and backward counting sequences with whole numbers to at least 1000.
NA3-3: Know counting sequences for whole numbers.
Specific Learning Outcomes

Identify numbers in the range 0–1000.

Identify all of the numbers in the range 0–1 000 000.

Identify and order decimals to three places.

Say the number one–thousandth, one–hundredth, one–tenth, one, and ten, etc, before and after any given number.

Description of Mathematics

Number Framework Stages 5 to 7

Required Resource Materials
Activity

Explain to the students how each place-value house is broken into hundreds, tens, and ones.

Help the students to read the numbers in their house positions. In particular, assist the students to read numbers like 34 009 083 080, where the zeros must be noticed but are not read out loud.

Notice the first house needs no name. (It is called “The Trend Setter House” in Material Master 4–11 because it starts the pattern of column names within every house.)

Give the students a number and get them to add the place-value houses then read aloud the number. Once the students’ knowledge is secure ask them to read numbers like 34 908 345 002 without houses.

Extension Activity

Go on to reading numbers in the quadrillions and quintillions houses, and/or include the decimal place values tenths, hundredths, thousandths, ...
