A ready-to-run fraction substitute lesson
A 45-minute Grade 4 review of equivalent fractions: a board-ready teaching sequence, eight student questions, one worked example, answers and a handover note.
Anonymous group code: __________ Date: __________
Warm-up
Sketch the whole and label the fraction. Use equal-sized wholes when comparing.
c2. Compare 1/2 and 2/4. Choose <, =, or >. The wholes are the same size.
Worked example · Same amount, new name
example. Show why 1/2 = 2/4 using two same-sized rectangles.
- Draw two rectangles of the same length and width.
- Divide each into two equal parts and shade one half.
- Divide both halves of the second rectangle in half again.
- It now has four equal parts and two are shaded. The shaded amount has not changed.
Worked example: 1/2 = 2/4. The whole and shaded amount stayed the same; only the number and size of the parts changed.
Partner practice
Draw, compare and explain. Take turns checking the same whole and equal parts.
c3. Compare 2/3 and 4/6. Choose <, =, or >. The wholes are the same size.
c6. Compare 2/5 and 4/10. Choose <, =, or >. The wholes are the same size.
Independent practice
Use a drawing or a calculation to support each answer.
c7. Write the value shown by eight of twelve parts. Strip model: 1 same-sized whole, each divided into 12 equal parts; 8 parts are shaded altogether.
h2. A partner says 2/3 = 3/4 because both numbers increased by one. Give a counterexample.
Exit ticket
Complete both without help. Explain the equal amount, not just a rule.
