Developer: demografix pty ltd



Created by teachers for teachers…
Number Lines is the first app released as part of the demografix ‘iPads for Schools’ program. Teesdale Primary School, a school in Victoria Australia, submitted and crafted the ideas, features and functions of the app to suit them and the National Curriculum, while demografix developed and built the app in association with TouchScreenCraft. A percentage of the sales go back to the school as iPads for their classrooms.

Number Lines includes a variety of number lines from with multiple combinations (1-20, 20-50 as examples and multiple sequences) that can be used for supporting the teaching of addition and subtraction from Foundation to Year 4. In fact, any number line can be created and the number lines scroll horizontally to provide a true number line experience. Great for illustrating strategies in these functions and includes the ability to be able to “draw” on the screen so that students can track their counting. Used to illustrate strategies such as counting backwards and forwards in the nearest 10’s.


Create your own Number Lines…
As a demografix app it has the ability to create, save and share your own user created number lines, student profiles and includes settings that allow the teacher to hide any external links or to lock the app via a PIN. Lines can be created with a user defined number of minor marks allowing for decimals and large number lines. The app also allows for negative numbers and currency lines in four currencies. Teachers can integrate images (how many, what fraction or number recognition) and audio recordings for a rich learning environment. Teachers can enable a student to record an audio answer to outline the strategy being used. Completed lessons can be automatically emailed to the teacher and include the student audio recordings and all student tracings.

Comments from Kaye, a teacher at Teesdale Primary School…
“I’m really impressed with the app. I had time to really go through the Foundation levels today and it has turned into so much more than I ever envisioned. I’m particularly pleased with the audio features and the image counting. It works really well.”

“I used “Number Lines” in class again yesterday, the Decimal 0.1 line and used it for a money lesson to calculate change. (How much change from $6.00 if you spent $2.40) Worked really well.”


“Just been using Number Lines in Grade 1 and 2 and it is working really well. Students are working on subtraction worksheets. They have been working with numbers to two place values and trading between the 10’s and units columns, so they have only been using the 1s line up to 20. Really helped a lot to work independently.”
