Here is one whole strip on the board, and it has been split into ten equal pieces. If we shared this one bar of chocolate fairly between ten people, how much would each person get? What could we call one of these ten equal pieces?
The interactive shows one whole flat split into ten equal rods, with some shaded. Watch how many rods are shaded and read it three ways: in words, as a fraction, and as a decimal. Notice where the decimal digit sits.
Now we shade tenths together. The top strip is split into ten equal parts. I call out an amount, one of you shades that many parts, and we all say it two ways: as a fraction and as a decimal. Then press Reset for the next one.
A decimal counts the shaded tenths: 0.8 means eight of the ten equal parts.
In your maths copy, draw a bar split into ten equal parts. Shade four of them. Then write the amount two ways underneath: 4/10 and 0.4.
Today we shade these amounts on the strip, in this order: 0.1, then 0.3, then 0.7, then 0.9. Each one adds a little more, and after each shade we check it together. Pupils take turns at the board and the class reads each amount as tenths, as a fraction, and as a decimal before we press Check.
