Here is a number line that runs from 0 to 1, and someone has split it into ten equal steps. Look closely at the very first little step after 0.
What decimal do you think sits right there, on that first step? Hands up when you have a number in your head.
The interactive shows a marker on a number line split into ten equal tenth-steps. Look at where each marker is and count the steps along with us. Later the line runs to 2, so notice where we start counting from.
Now we work through these tenths together on the number line, in this order: 0.2, then 0.7, then 0.4, and finally 1.5. One of you comes up to move the marker each time. Everyone else counts the equal tenth-steps out loud with us, so we all find the answer together before we check where it lands.
In your maths copy, draw a number line from 0 to 1 and split it into ten equal steps. Then label these three tenths in their correct places:
Count the equal steps carefully from 0 each time before you write the label.
Now we place these tenths on the line, in order: 0.3, then 0.6, then 0.9, and finally 1.2. The last one is past the whole number 1, so we count the steps starting from 1.
One pupil comes up to move the marker and press Check each time. Everyone else predicts and counts the tenth-steps together first, then we all watch the check to see if we were right.
