# Summary of Unit of Work:

In order for students to progress in mathematics they need a strong foundation in Place Value. Using the inquiry process; tuning in, finding out, sorting out, going further, making connections and taking action, students expand their knowledge on decimals.

The unit begins with a tuning in, involving a pre-test with opportunities to learn through asking questions, videos, games, hands-on material, songs and explicit teacher instruction. At the end of the unit the students plan how to use their new knowledge on decimals and also complete a self-assessment rubric.

### Mathematics (Number and Algebra):

Level 2

• Recognise, model, represent and order numbers to at least 1000 (ACMNA027

Level 3

• Recognise, model, represent and order numbers to at least 10 000 (ACMNA052

Level 4

• Recognise that the place value system can be extended to tenths and hundredths. Make connections between fractions and decimal notation (ACMNA079

Level 5

• Recognise that the place value system can be extended beyond hundredths (ACMNA104

Level 6

• Add and subtract decimals, with and without digital technologies, and use estimation and rounding to check the reasonableness of answers (ACMNA128
• Multiply decimals by whole numbers and perform divisions by non-zero whole numbers where the results are terminating decimals, with and without digital technologies (ACMNA129
• Multiply and divide decimals by powers of 10 (ACMNA130
• Make connections between equivalent fractions, decimals and percentages (ACMNA131

# Unit Overview:
