Order decimal tenths between 0-1 on a number line

0-100, 0-10, 0-1

Time frame: 10-15 minutes

Audience: Whole class, small group, individual

Materials: Prepare 3 sets of number cards: 0, 10, 20, 30 , 40, 50, 60 ,70, 80, 90, 100 & 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 & 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1 and string, masking tape or chalk to create a number line.

Summary: Start with the increments of 10 and place the 0 and 100 at either ends of the number line. Then continue to place the rest of the numbers with the emphasis on equal spacing. Don�t take these cards down.�

Guiding questions: When placing cards 0-100, ask the students which of the remaining numbers will be the easiest to place. Hopefully most students will say 50 and ask them to explain why. Repeat this process with cards 0-10 and ask which is easiest to place and why. What is the connection between 100 and 10? Between 10 and 1? What is the connection between 50 and 5? What is the connection between 5 and 0.5?

Math Antics - The Number Line

Timeframe: 10:12 mins

Audience: Whole class, small group, individual

Materials: device to watch

Summary: The video shows how numbers are placed on a number line. It is scaffolded and starts with whole numbers before making the connection to tenths.
Guiding questions: Pause when each number line is almost full and ask students to identify the patterns that they notice. Then have them turn and talk to predict what number will be next.

Count by Tenths 

Timeframe: 30 minutes

Audience: Individual 

Materials: Number Line with 0 - 1 on this

Summary: STORY - In q small village called Numberville, all the numbers lived peacefully on their number lines. The whole numbers had their own spaces, but in between them, there were mysterious places that the whole numbers couldn’t reach. These were the homes of the Decimal Detectives—small, brave numbers that lived between the whole numbers. One day, Detective Decimal, who lived between 0 and 1, noticed something strange. The Decimal Detective Squad, made up of numbers like 0.1, 0.2, and 0.3, realised they had an important mission: to help the other numbers understand how they fit on the number line. Detective Decimal decided to take the squad on an adventure. They started at the number 0 and moved towards 1, each one stepping forward one section at a time. As they moved, they counted their places out loud: Zero, one tenth, two tenths and so on until they reached "ten tenths," which they know is equal to 1 whole. Students label their number line with correct tenths. Decimal Number Line Setup:
Provide each student with a blank number line marked with 0 on one end and 1 on the other.
The number line should be divided into 10 equal sections, but without the decimal numbers marked.

Guiding Questions: Could we extend this? YES - Students continue their number lines going up to 2, then 3.
Following on from this they could label hundredths.
