A 12-minute number-line rescue
Count equal intervals instead of tick marks. Ask three short questions, model one example, practise three times, then check a new situation.
Anonymous group code: __________ Date: __________
0–3 minutes · Quick diagnosis
Try all three. Explain with words, a sketch, or objects.
d2. Starting at 0 on a line divided into sixths, a student counts the zero mark as “one” and labels the next mark 2/6. Repair the label.
d3. A line from 0 to 1 has three gaps of different lengths. Can its marks be labeled 0, 1/3, 2/3, 1 in order? Explain.
3–6 minutes · One worked example
Trace each equal gap as you count.
w1. Draw a line from 0 to 1 and locate 3/4.
- Mark and label 0 and 1 first.
- Partition their distance into four equal intervals; this needs five marks including both ends.
- Count three intervals from 0.
- Label the endpoint of the third interval 3/4.
Worked example: 3/4 is the endpoint after three fourth-length steps from zero.
6–10 minutes · Three practice tasks
Draw or explain your thinking.
p1. Draw a unit line with 3 equal intervals. How many marks are needed when both 0 and 1 are included?
p2. On a unit line split into eighths, what fraction is reached after five equal steps from 0?
p3. A line has labels 0, A, B, C, 1, all equally spaced. Name B.
10–12 minutes · Independent transfer
