Remember: One whole is ten tenths. Each bead on the row is one tenth, and we write tenths after a point: 0.1, 0.2 and so on.
Read and answer
Read the story, then answer.
The chocolate barMia and Ben find a chocolate bar made of ten equal squares. The whole bar is one whole, and each square is one tenth. A row of ten beads is like the bar: the whole row is one whole and each bead is one tenth. Mia eats two squares, so two beads slide across. That is two tenths, and we write it 0.2. Ben eats four squares. Now six tenths are gone and four tenths are left.

Tenths of a bar
1two tenths The bar is ten equal squares, and each square is one tenth. Two out of ten is two tenths.
210 Ten equal squares, and each one is a tenth.
30.7 Zero point seven is no wholes and seven tenths.
4B Four beads across the row are four tenths: 0.4. The full row of ten is 1.0.
5True Five out of ten equal parts is half.
60.7 Three beads and four beads make seven tenths.
70.4 Nine beads take away five beads leave four tenths.
81-B, 2-A, 3-C, 4-D After the point comes the number of beads slid across. Ten tenths is one whole, 1.0.
92, 1, 3 More beads across means more.
10No Six beads is more than two beads, so six tenths is more.
11ten tenths, 1.0 Ten tenths fill the whole row, and we write it one point zero.
124 Four out of ten equal parts is four tenths.
