A 60 minute lesson in which students will explore tenths as fractions and in decimal notation.
- Write the sentence, ‘A decimal is…’ on the board. Ask the students to suggest possible endings to this sentence. Record these on the board to be referred to later in the lesson. Do not be concerned if the students have very few suggestions at this stage.
- Display and discuss slide 5-7 of the Introducing Decimal Numbers PowerPoint. Encourage the students to suggest other examples of decimal numbers being used in everyday life, as well as some other examples of situations where decimal numbers are needed in order to be precise.
- Explain decimal place value to the students, as outlined on slides 8-10. Write some additional examples of decimal numbers on the board and ask the students to identify which digit holds each place e.g. Which digit is in the tenths column?
- Demonstrate how tenths may be written as a fraction and in decimal notation, as outlined on slides 11-13.
- Display the review questions on slide 14. Monitor and support the students as they individually complete the questions on the slide.
- Display and discuss the answers to the review questions on slide 15. As students correct their answers, encourage them to raise any queries or concerns.
- Revisit the tuning in activity. Ask the students to suggest any additional sentence endings and add these to the collection on the board.
- Allow students who are finding the review questions challenging to work in a small group with a teacher or teacher aide.
