This presentation provides three days of teaching that cover the objective:
- Multiply and divide fractions
It includes starter activities, whole class teaching, group activities, practice sheets and mastery questions. It can be used on a variety of interactive whiteboards.
Day 1 Teaching
Sketch a garden divided into quarters on the board. Say that one quarter is for growing fruit. In that part, half of it is for strawberries. Show children how to find 1/2 of 1/4. Demonstrate that this is 1/8. Use other examples to derive a rule for multiplying fractions.
Day 2 Teaching
Show 3 pizzas. Two children choose a pizza, e.g. the pepperoni, with 3/4 of it left. Draw line to cut remaining pizza in half. What fraction will each child get? Record 3/4 ÷ 2. Repeat for the other pizzas. Repeat with 3 children sharing what is left, then 4.
Day 3 Teaching
Write 1/2 × 3/4 and ask the children to remind you how they can do this. We can multiply the numerators then multiply denominators. Demonstrate, finding 3/8 as the answer. Write 2/3 ÷ 3. Draw a cake divided into thirds. Shade 2/3 and then divide each of the shaded thirds into three parts. So, 2/3 ÷ 3 is the same as 1/3 × 2/3. Show that we get 2/9.
This teaching is part of Hamilton’s Year 6 Decimals and Fractions block. Each Hamilton maths block contains a complete set of planning and resources to teach a term’s worth of objectives for one of the National Curriculum for England’s maths areas.
