## Ordering fractions and decimals - Lee : Grade Commentary

### Other Work Samples for:

Lee has demonstrated extensive knowledge and understanding of the relationships between fractions, decimals and percentages. Most of the number line plotting is accurate, with the exception of 0.05 which is too far along. The relationship between fractions, decimals and percentages has been explained numerically and in words. All three concepts have been linked well. There is excellent use of mathematical terminology in the reasoning and explanation. Lee has listed all possible numbers, but not necessarily in a logical order. This work sample demonstrates characteristics of work typically produced by a student performing at grade A standard at the end of Stage 2.

The student has an extensive knowledge and understanding of the content and can readily apply this knowledge. In addition, the student has achieved a very high level of competence in the processes and skills and can apply these skills to new situations.

## Foundation Statement strands

The following strands are covered in this activity:

• Working Mathematically
Students ask questions and use appropriate mental or written strategies, and technology, to solve problems. They use appropriate terminology to describe and link mathematical ideas, check statements for accuracy and explain reasoning.
• Number
Students count, order, read and record numbers up to 9999 and use mental and written strategies, including the formal written algorithm, to solve addition and subtraction problems involving numbers of up to four digits. They use mental strategies to recall multiplication facts up to 10 x 10 and related division facts and use informal written strategies for multiplication and division of two-digit numbers by one-digit numbers. Students model, compare and represent simple fractions and recognise percentages in everyday situations and they model, compare, represent, add and subtract decimals to two decimal places. Students perform simple calculations with money and conduct simple chance experiments.
