Think firstA frog jumps 1/4 at a time, from 0
A frog starts at 0 and makes 5 jumps of 1/4. Where does it land?
Decide first, then press Next. Count the jumps, not the whole numbers.
A number line from 0 to 2 with a box saying each jump is 1/4. Then small marks at every quarter, labelled 1/4 to 8/4. Then five numbered hops from 0, landing on 5/4, which is ringed; the sentence 5 × 1/4 = 5/4 = 1 1/4. The last step shows jumps of 1/3 up to 3.

The big idea
On a number line, 5 × 1/4 is 5 jumps of 1/4 from 0, landing at 5/4.
Same as the stripsA jump on the line is the same as one strip piece: both are one unit fraction. 4 jumps of 1/4, like 4 quarter strips, make 1.
Key word
- number line
- a straight line with numbers marked in order at equal spaces
