Consolidation and practice
These resources are to support children in guided or independent work. Roll over the highlighted resource for a description.
Decimal number line
This interactive teaching program (ITP) is an ICT-based tool to support the exploration of place value within whole and decimal numbers. Decimal number line ITP allows the child or teacher to select an interval from a given number line and show that interval divided into ten equal parts but on a bigger scale, which can then be repeated.
Opportunities to use and apply
Possible contexts include:
- sequences, e.g. What amount comes next in this sequence? £1.37, £1.47, £1.57...
- calculation, e.g. How could partitioning help you calculate
4.3 m + 3.5 m?
- measurement, e.g. Which is longer, 5.05 m or 550 cm?
- reading scales, e.g. What is the length of the cricket bat?
Confirming learning
Ask probing questions such as:
- Which is greater, 239p or £2.93? Why?
- A CD costs between £5.50 and £5.65. How much could it cost?
- How would you enter £1.10 on a calculator?
- Write a number that is bigger than 7 but smaller than 8. Can you explain what makes it bigger than 7 and what makes it smaller than 8?
- I make a sequence starting at £1.10 and counting in steps of 20p. Give me three numbers above £2.00 that will be in my sequence.
- Explain what the 3 represents in each of these amounts:
£3.50, 36.5 m, £1.53, 263.5 cm, £0.35
